They are more keen on what they consume and since the store menu has a lot of wheat, it needs to consider an addition of healthy menu such as salad in their menu. 

The store is facing a challenge of new entrant. There is less hindrance for new entrant in food service industry, therefore, the store loose the market share in the niche categories. Domino’s Pizza Davies Corner needs to develop an internal feedback system that will be used by sales team in the field in order to respond to this challenge. 

The store employees low skilled employees who are likely not satisfied with the store work especially when the working environment is more demanding. Their only solution to this is to quit and look for a job. This has been for challenging to the store since the rate of employees turnover is high. Its rivals employees professional and high skilled staff who are satisfied with their work and as result their production is high. 

Sometimes, customers feels like enjoying their meal out door but the store has a small eating joint that is so squized and can only fit a few number of their customers. The reason why the eating joint is squized is because their main focus is on take awares. This is a threat since customers will look for a store that has a comfortable eating joint.

The store has an opportunity to invest on Big Data Analytic which will help them to capture their customers’ details. They will be able to understand their customers better 


Change in consumers eating behavior creates a threat to Domino’s Pizza Davies Corner store. The government and the Non Governmental Organization (NGO) are mainly focusing on health awareness. People are able to access information on what is health and what is not. Therefore, this affects their decision on what to consume which has affected the store negatively. 

Their is an increase in the cost of store raw materials which has forced it to spend more. This has impacted negatively on the cash flow of the store. Competition has also made the store to spend more in order to remain competitive and retain the market share. 

The store faces competition both directly and indirectly. It faces local and national competition from Domino’s Pizza Hamilton, Domino’s Pizza Hillcrest. KFC and McDonald have indirect competition where customers prefer to consume burgers instead of pizzas. 

PESTLE analysis 

PESTLE stands for Political, Economic, Social-Culture, Technology, Legal and Environmental factors. PESTLE analysis presents information on the business operation challenges that are faced by Domino’s Pizza Davies Corner store in the extensive macro environment apart from competitive forces. 

Adjustment in the macro environment factors can impact Domino’s Pizza Davies Corner store directly or its rivals. It can also boost the store competitive advantage and the overall profit. 

Political factors

This aspect of PESTLE analysis deals with how government and its policies have effects on remote and macro-environment of Domino’s Pizza Davies Corner store. 

The government has ordered the citizens to avoid going to public places and stay home. This order was as a result of Corona Virus outbreak. This will reduce the number of customers who consumes the store product. It will later lead to close of the store. 

There is also a restriction order of closing the country boarders to foreigners. Other countries are not giving visas. This has reduced the number of tourist who is the potential customers for the store which is a threat. 

Evolving public health policies is a threat and an opportunity to Domino’s Pizza Davies Corner store. The government requires foodservice providers to produce products that are less unhealthy. The store will need to use more resources than usual. However, the store has an opportunity to adjust their production of healthy food. It can do away with artificial preservatives, colors and flavors 100 per cent in all of their products and still remain the same taste. 

There is an increase in the minimum wage of employees that is required by the government. The store has to spend more to pay the employees, thus the store returns and profit will be affected. 

Economical factors

This facet of the PESTLE analysis analyzes how economic conditions and trends on the remote or macro-environment affects business operation of Domino’s Pizza Davies Corner store. Change in economy has direct or indirect influence on business performance.

Currently the country and global economy has been affected by corona virus pandemic. The country economy is in recession stage and it will continue to be worse until the virus is succumbed. This has affected customers’ purchasing power which has led to decrease in sales. 

Consumer purchasing power has also been affected by the current outbreak of the virus. People are purchasing most basic and more important products rather than purchasing pizza from the store. This reduces the store sales and can also lead to increase in food waste. 

Social-Culture factors 

This PESTLE analysis helps to identify the social conditions that aid or confine Domino’s Pizza Davies Corner store operation. The social trends have an impact on consumer behavior. It also affects the remote and macro-environment of the restaurant in terms of revenue.

Changes in lifestyle trend where the customers want a healthy lifestyle. Social factors create a great opportunity for the store business development. It has an opportunity to change its products so that they can satisfy their customers’ preferences. It also has an opportunity of producing healthy products such as salads. This also imposes a threat to the store since they can lose customers to their competitors depending on the product they sell. 

Technological factors 

This analyzes how technologies and related trends have impacts on Domino’s Pizza Davies Corner store remotely and macro-environment. The restaurant needs to adapt to the new technology for its own survival in the competitive environment. 

The rate of technology diffusion can either be a threat or an opportunity to the store. Slow speed diffusion of technology gives the store time to adapt to the new technology while fast speed technology al diffusion gives limited time for the store to adopt, cope and be profitable. 

The large number of the population has access to Smartphone and Internet therefore, they are able to order online and track their delivery. This is an opportunity for the store since the number of potential customers is increasing almost every day. 

Use of technology can help the store to reduce food waste by tracking where the food waste is being generated and calculating the cost that the store incurs when food is wasted. 

Environmental factors 

This factor explores how Domino’s Pizza Davies Corner store has been affected by trends in natural environment and effects on the business remote and macro-environment. 

Climate change is a threat to the store since it determines the availability and supply of the store agricultural materials. It also affects the supply chain of the store. This creates a threat to the store since it will spend more to purchase their raw materials for their product. 

Environmental sustainability is a major concern globally. Domino’s Pizza Davies Corner store needs to research and invest on how they can reduce, reuse and recycle food waste. 

Legal factors 

This facet of PESTLE analyzes the impact of laws and regulation on Domino’s Pizza Davies Corner store. Amendments in legal systems and new laws impose new requirements by the restaurant. 

Increase in legal minimum wages impose a threat to the store since they will spend more to pay their employees thus, it reduce the store profit. 

Competition laws are a threat and an opportunity for the store. The store has an opportunity to develop competing strategies and on the other hand its competitors impose a threat of winning their customers. 

Health and safety law requires the store to sell healthy products that are safe for human consumption. The store also need to label their products such details include expiry date, product ingredients.

There is a continuous increase of food wastage globally from all areas of food supply chain. In developing countries, food wastage mostly occurs on the end of food supply chain while in developed countries, food wastage is a problem in consumer plate waste. Food wastage is categorized into three. Avoidable food waste for food that was edible at some point, potentially avoidable food waste and unavoidable food (Leo, Nina & Matthew 2017)

Almost a third of food produced globally for human consumption go to waste which is almost 1.3 billion tonnes yearly. The food production resource is demanding. The food waste has an indirect associated by a wide range of environmental effects such like water and air pollution, soil erosion, and greenhouse gas emissions (Gustavsson et al., 2011). Food waste occurs in food production, storage, transportation and management of food waste (Mourad, 2016).

Food waste is an urgent issue that need to be focused since it has a negative impact on the environment and social economy. The restaurant needs to educate their staffs on ways to prevent this issues. Measures needs to be developed in order to curb food waste. 

Research problem

Food wastage is an environmental, economical and social problem. Management of food wastage has been a global issue for many years which has affected both developed and undeveloped countries. In the past few years, there were various measures that were proposed and implemented addressing food wastage issues. There is need for more research that ir required to be performed in order to identify potential measure that can be put in place in order to solve food waste issues as suggested by recent researchers. The available resources on food waste measure are not enough based on the environmental and social-economy performance (Goossens et al. 2019).

Food wastage is a cross cutting issue that involves various stakeholders in the food chain. Various literature reviews put their focus on how individuals can change their attitude and behavior.

Food wastage problem cannot be entirely being solved but it can be reduced (Webder & Khademian 2008). This issue requires engagement of various players in different activities and at a different level. 

Food waste management

Food wastage shows that the food production and consumption system is not suitable. Various researchers have not found a consistent definition for food wastage. This research study defines food wastage as stated by Food and Agriculture Organization of the United Nations (FAO) being the quantity of food wasted within the food supply chain. Food is defined as a product  that is consumable by human being (Gustavsson et al, 2011).

There are several ways which can results to food wastage such as Poor supply chain management, contamination of stored food by pests, inappropriate cooking methods, Presence of contaminants such as dirt or mould, malfunctioning appliances (such as refrigerators) and Consumer behavior.

Storing food in uncontaminated environment such as free from sunlight, water chemicals will help to manage food waste.  

Food waste generation

There are several ways where food can be lost or wasted in food value chains, such as during purchase and storage, when preparing food, when and after serving which is known as plate waste (Betz et al., 2015). Many researchers have not agreed on various categories of food wastage. (Silvennoinen et al. 2015) classify food waste as initially edible or initially inedible such as peeling of vegetables bones and coffee grounds. (Beretta et al. 2013), categorize food wastage as avoidable, partially avoidable and unavoidable. Eriksson et al. (2017) differentiate source decline during production and administration or management of unwanted food waste.  Food wastage occurs at every stage of the global food value chain, from agricultural production to final consumption). 

Food wastage is perceived as a preventable challenge which drove the United Nations to come up with a goal number 12.3 that is included in the 17 Sustainable Development Goals which are to be achieved by 2030. The reason for this goal is to reduce food waste that is produced by retailers and consumers and also reduce food waste in the food supply chain.   

at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses” (UN, 2017).  These goals are achievable since there have been some feasible evidences (Beretta et al. 2013).

Food waste management initiatives

Food waste avoidance will be firmly interlinked with the management and consumption practices. The researchers have only explire the importance of food waste measurement in the food supply chain. This will help to capture the exact dimension of the food wastage problem, determine various sources of food waste and to define an effective measure to monitor reduction over time (Beretta et al., 2013; Betz et al., 2015; Papargyropoulou et al., 2016; Silvennoinen et al., 2015). Further research needs to be conducted in order to identify an effective  managerial resolutions for food waste alleviation in food service sector . 

Provide customers with plastic containers so that they can take their food home. Even though the portion size is reduced it is not the genuine solution because people will always leave food on their plate regardless the portion size (Pers. Com., Monzón, 2017).

Preventive measures 

Whatsoever the cause or the source of food wastes has been given great attention by cafes and restaurants. The main goal is to prevent it from happening (Tuppen, 2014). Some strategic and actions has already been set up to reduce food waste. Such actions include increasing employees awareness, more focus has been put by restaurants and café on the amount of food waste and the source of that wastage.

Inventory preventive measures

Evaluation of supply chain by the restaurant on the product quality, timely delivery, the ability to support required volume, consistency of the products and price can help to prevent food waste (Tan et al., 2002).

Restaurants can reduce untracked items in inventory by employing activity-based costing methods that will enable them to track the amount of inputs each dish requires (Vaughn et al., 2010).

The use of technology can help to improve inventory control in restaurants and cafes for every food inventory product. They need to incorporate handling and temperature control requirements, shelf life and expiry dates. Inventory control helps to reduce over-ordering thus minimize food waste (Charlebois, 2015).

Operation preventive measures

Other strategies include menu engineering, tracking of food wastage, activity-based costing, plate size reduction, customer fining, leftovers donation, delivery examination to make sure that the product is not contaminated, damaged packaging and avoid over trimming during preparation (Pirani & Arafat, 2014)

Betz et al. (2015) identified some measures that can be implemented to reduce food wastage. The researcher categorized them according to stages that they were generated. This includes storage and purchase, preparation and cooking, serving or delivery and consumers. Prevention and food waste reduction measure n storage and purchase include storage management optimization like periodic control of expiry date. On preparation and cooking, over production should be avoided, reuse leftovers, control preparation losses and train employees on how they can reduce food waste and fast cool down the food in order to prevent micro organisms growth.

Legislation plays a major role in the achieving a successful food waste management. Practices obtained from laws and regulation such as introduction of requirements like reporting on food waste and standardization for food waste calculation, indicating the expiry on packaged food (Pirani & Arafat, 2014).

cause of food wastagePossible measures
GeneralThere is lack of top management or employee awareness on food waste measures, no support or training.Enhance support by increasing resources, train employees and create awareness.
There is minimum  measuring and food wastage monitoringPerform regular food waste audits for better understating of quantity and source of avoidable food waste. Inform the employees the result and the progress.
There is minimal perception of financial benefit. Many restaurants are focusing on  food wastage instead of prevention Record the cost of food wastage in the kitchen daily. The management should understand the full cost of avoidance food waste through preventative percipient. The management can use audit data to calculate full cost of avoidance food waste, disposal costs and use that information to estimate the proportion of wasted food.
Pre-consumptionfood waste preparation through inexperience and failure to reuseDetermine areas where kitchen waste can be reduced internally.
lack of measuring the required quantity when cookingUnderstand legal requirements regarding external distribution or food waste donation to people or animals.
poor forecasting or planningImplement forecasting and planning procedure.
Limited technical use such as poor refrigeration.Perform regular maintenance check on equipments such as cleaning, changing coil on refrigerator and ensure that they are properly sealed.
Post-consumptionExcess portion sizesEnsure that the portion sizes are suitable. This can be achieved by inspecting the customer plate waste or talking to them. Provide different range of portion size.
customers’ cultureInform and educate customers to take what they can finish and how food wastage has a negative impact on ecosystem and society. Charge customers who with plate waste. 
lack of customer awareness
Customer ordering too much.
There is minimal perception of financial incentive by customers.

The total cost of pre and post-consumption food waste on cafe or restaurant produces might be as a result of top management and employee attitudes towards sustainability and food waste prevention. Most restaurants food waste management fails due to unrecognized full cost pricing when it comes to the total costs of food waste to their business. The prevention of food wastage requires top management and employees to be committed and work together to prevent food wastage. 

Food wastage Measuring and monitoring plays a vital role towards food waste prevention (European Commission, 2011b; Gunders, 2012; LeanPath, undated; Nordic Council of Ministers, 2012). Separation and measurement of food waste can impact employees or customers positively by being aware of the quality of food waste that they generate and aggregate their effort to reduce food waste (European Commission, 2011b).  

When the source of food waste is identified, helps cafe and restaurant to determine the action points which they can implement to reduce both pre- and post-consumer waste such as making the guests aware about the amount of food waste produced each day and involving staff in reduction measures (Pre-waste, 2012). 

Innovation and technology in food management


Advancement in technology and innovations has improved and reduced the cost of food waste management. It is a gradual improvement concerning the current mechanism and distinguished act that are linked with waste minimization (Beise & Rennings, 2005). 

Use of technology and innovations helps to focus on reduction of food wastage by either developing new processes and operational improvements or advancement in current technology. For example, Wang et al. (2013) development of green  restaurant  management  standards which includes green  foods,  green  environment  and equipment and green management and social responsibility. These initiatives vary in the degree of newness to the adopting firm and, for the most part, require a low degree of new knowledge (Dewar and Dutton, 1986). Some researchers found that application of the Internet of Things (IOT) and network technology helps to improve food waste management in terms of collection, transportation or delivery. These require sophisticated management systems and which involves high level technical skills (Wen et al., 2017).

The use of technology along the whole food value chain from farming to placing food on the plate has an extensive probability of reducing the food wastage. Artificial intelligence (AI) technologies like computer vision, machine learning and data analysis have the key to enhance the food value chain from the farm to trucks to stores and restaurants in an attempt of reducing food waste.

Some restaurants are using Smart Scale to Reduce Food Waste. It helps them to accurately measure the certain amount they product they will require. This technology helps to enhance food traceability process, helps to decrease amount of food that go to waste, and efficiency in transportation and management of food product is raised. This has a direct impact on economic and environmental sustainability issues. 


Increamental innovation helps to utilize the current business processes and technology.  Thus, it is relatively less complex than profound innovation.  Radical innovations helps to identify various techniques that can be used in food waste management. They display a clear departures from current practices (Carrillo et al., 2010). Basic innovations in food management needs a better understanding and commitment , takes more time, and requires a lot of resources. It also associated with greater risks for market  uptake and on the other hand  they  can  lead to  great  significant  contributions  to  environmental sustainability. Nevertheless , there are scarce radical innovations that can be endorsed unless  a business has an internal know how resources about the complex and expert in innovation, how to interpret and absorb them (Souto, 2015).   

In the past, food waste was not part of managers’ practices until now where they are involved. The management of food waste needs to be creative, all parties should be aware and invent new mechanisms (Chou et al., 2012). 

Winnow builds artificial intelligence tools that assist kitchen employees to run more profitable and sustainable kitchens.  The AI has recently launched a tool known as Winnow Vision that is designed to automatically track food waste in the kitchens. This technology uses computer vision which is in form of artificial intelligence that helps kitchen employees to identify waste, cut costs and save time.

Camera installation with a set of smart scales plus machine learning technology like the one in autonomous vehicles, Winnow Vision helps to recognize different foods that are being thrown away compute the financial and environmental cost of wasted food in restaurant kitchens (Williams, 2019).

Investing in technology helps restaurant to prevent kitchen food waste and prevent from happening. It is also helps to accurately forecast the future demand and get prepared. Tenzo application is one of the technologies that are used in forecasting. 

Tenzo mobile application aids restaurant managers or the owner to forecast demand like how many people to staff and when or the amount of food to be ordered. It also helps them to identify those staffs that are performing better, in regard with up-selling or resulting to positive social media mentions, or to identify areas that are performing best or what menu item needs to be de-listed (Steve, 2017).

Through machine learning, Tanzo helps to predict future sale of a restaurant, therefore, it helps to reduce food waste. 

Reuse, recycle and food wastage reduction

Food waste recycle

Restaurants can implement the popular program of Reduce, Reuse, Recycle for waste management this includes the management of food waste, plastics, glass, and paper/ paper Boards (National Institute of Environmental Health Services, 2013). Waste reduction at the source is the main part of reduce, reuse and recycle. Reduction should always start fro, procurement department by purchasing what is required. Procurement is a very important factor to restaurant environmental sustainability.

Recycling of food wastage is efficient and effective than disposal. This process helps to divert waste from the landfill or elsewhere in the solid waste stream and ensure ongoing value when the item is converted into something useful, such as a soil amendment with composting.

Food waste can be used to generate energy for example it is used to generate biogas that is used as a fuel in some cars (Patterson et al. 2011) 

Recycling is a program that has a positive impact on food waste management (Wilson, Velis & Cheeseman, 2006) recycling in a restaurant is divided into two categories, a program with a full time recycling manager who oversees the recycling operation and the one that adds responsibilities of recycling to the employees (Lounsbury, 2011).

Snarr & Pezza (2000) Restaurants can avoid food waste by creating reduction consumption by reusing and recycling by donating food. Food waste can be recycled as animal feeds or used to make compost or renewable energy.

There are Ecological benefits of separating food waste collection. Separated collection of food waste is the best option for the environment, since waste should be recognized as a new resource within our world of resource scarcity (Stahel, 2016). Additionally, the processing of food waste results in lower CO2 emissions (Andersen et al., 2011). Sadly, there are few restaurants that choose ecology over economy (OVAM, 2011).

Reduction and Recycling measures

Separate food waste collection in restaurant helps to save time and money. The cost of disposal is relatively high than recycling (Hogg et al., 2016)

Correct food waste collection and recycling has a range of potential benefits (Mills & Andrew, 2014). It helps to divert biodegradable waste from landfill, reduce waste disposal costs since the landfill costs is high, reduce environmental impacts which is accompanied by landfill (toxicity in leachate, landfill gas emissions, etc.), Decrease greenhouse  gas  emissions  by  removing  the  putrescent  content from landfill sites, helps to Improve recycling rates. 

The most effective way in management of food waste is to reduce the source of food waste. The system needs to be designed that can help to inhibit, reduce and avoid food waste in the first place. 

This creates an opportunity for the business to save food, increase profit and the same time impact positively towards the environment. 

Through reuse, restaurants find a secondary ways to create a value from an item that was considered as a wasted. There are possible ways the restaurant can reuse waste food such as reallocating the leftovers elsewhere on the menu. Restaurants need to be careful and should comply strictly with food safety guidelines. They can also donate waste food to program that will distribute to the needy.  

Food and Safety

Impact of contaminated food

Food safety is vital in public health matters to avert or curb food-borne illnesses. In response to the increase in the number of food-borne illnesses, most of government across the globe is intensifying their efforts to improve food safety. According to the World Health Organization (WHO) contaminated food results to 1.5 billion cases of diarrhea in children annually which increase premature deaths. This affects both developed and developing countries. 

Poor nutrition and decline in food consumption is as a result of age-related decline in immune system functioning which gets weak in toddlers and old age which reduce the ability to fight food borne pathogens, resulting in food borne illnesses (Buzby 2002). 

Contaminated foods are not safe for human consumption and when consumed it develops symptoms of illness, which usually do not appear for at least one day after ingestion of the contaminated food, usually include diarrhea but vary according to the type of organism ingested (Nester et al. 1998; Jones 1992; de Vries 1997). 

Legal requirements

In order to enhance food safety in food service industry, it is important for restaurants to comply with the modernization act of food safety in which the main elements include preventive controls and hygienic design of equipment (Piotter, 2018). The hygienic design of equipment is crucial for the success of this program and in processing the different food items in a safe manner. 

The packaging of restaurants products should not contaminate the food. The basics in this regard are inspect able, cleanable, chemical cleaning as well as sanitizing solutions, corrosion-resistant, non-toxic and nonporous.

Food waste

Food is one of the basic needs to human while food waste is one of the major issues that are currently faced by humanity globally.  Food waste is also an economic and environmental problem (Purabi et al. 2016). Hence, it is an environmental, socio-economic issue. 

Every year, about 1.3 billion tons of food are termed as lost or wasted globally (FAO, 2013), this represent a considerable share of the overall food produced (Lundqvist et al. 2008; Parfitt et al. 2010). 

Food insecurity

The rate of food wastage is considered to be high in developed countries Buzby & Hyman (2012),  on  the contrary ,  842 million people  in poor countries has been estimated to experience chronic hunger (FAO, 2013). This develop a question whether food wastage need to be decreased along food supply chains (Curtis et al. 2016; Martinez-Sanchez et al. 2016; Muriana, 2017; Wilewska-Bien et al. 2016). 

Customers eating behavior and requirements have transformed. Increase in working hours and days, change in demographic and economic change has resulted to growth in catering services. This increases the rate of food wastage either by the providers or consumers Joanna et al. (2020).  Sustainable Development Goals number 12 which was agreed by United Nations General Assembly, pertain sustainability consumption and production patterns. The goal is to decrease global food waste by retailers and consumers per capita and reduce food waste that is generated in supply chain.

Impacts of food waste

In New Zealand, food wastage is one of the main environmental issues that are currently being addressed by individual, industry and government. About 24,372 tonnes of food get to waste yearly in New Zealand cafes and restaurants. 61 percent of this food waste is avoidable but the rest is unavoidable (Chisnall 2018). 60 per cent of waste food is a preparation waste such wastes are created when cooking such as vegetable peelings, food cooked in correctly, poor storage and unsold food and 33 per cent is plate waste which customers did not consume and finally, 7 per cent is food spoilage that goes bad before consumption Jones (2018).

Food waste and losses in the supply chain has a negative impact on the resources usage such as freshwater and cropland and where an additional billion people could be fed if crop losses were halved (Kummu et al., 2012). 


This involved the methods that was used to collect data from the respondents. The primary data was obtained from the manager and an employee at Dominion. A manager and an employee were chosen as sample participants for this research since they are well informed about the store operation and the measures and action they take to reduce food waste. This helps the researcher to gather relevant and correct data required. Therefore, a qualitative method was used for this research. The manager was chosen because he is well informed about the internal and external operation. The employee was chosen since they have knowledge on the amount of waste food per day and the cause. 

Data collection method and design

Interviews was the data collection techniques that was used. 

Interviews as a method of collecting data will also be used. This method will specifically be used for collecting information on the suitable practice of food wastage management in Dominions.

However, the researcher assured them that the information is for academic purpose only and there is no victimization. Therefore, they will be persuaded to participate in the study.


The participants participated in this research willingly, they were not forced to be interviewed or fill in the questionnaire. They were not forced to answer questions; they did not want to answer a particular question the researcher asked them the next question.

Research result

Total cost of avoidable and unavoidable food waste

After the interview and collection of the questioners, the researcher found out that Domino’s Pizza Davies Corner store avoidable food waste cost is relatively high and the avoidable food waste is relatively low. The manager stated that the employees are not aware or trained on how they can reduce avoidable food waste and the measures that are required have not yet been introduced in the store. 

The manager stated that most of avoidable food waste is caused when preparing food. Employees do not measure the required amount. The employees also indicated that they have not been provided with equipment that would help them to measure the exact amount required. 

The estimated cost for avoidable waste food is about AUD 9,000 per week while that for unavoidable waste food is about 2,000 per week. This has affected the store revenue or profit. 

The store manager indicated that food waste was being measured, but further analyses or attempts to understand the implications were not made. The manager and the employees do not have knowledge on how measure food waste, which illustrates just how prevalent and problematic the knowledge gaps exist between the food business services and the policy makers.

Furthermore, the methods for measuring food waste were solely visual and highly inaccurate. Visual measuring should not be considered an efficient method because accurate information and cannot be gathered, especially from trash bags that are not transparent.

This practice may allow restaurateurs to claim that only small amounts of food waste are being produced.

Food waste and its impact 

According to the participants’ point of view, they stated that food waste has a negative impact towards the environment, economy and society.

The employees stated that they lack knowledge on how they can help to reduce food waste in the store. They indicated that they need training and resources in order to reduce the amount of food that go to waste. 

The manager and the employees indicated that they are not aware of the other disposable options for their food waste. The government should provide information to businesses on different ways to expose their food waste and reduce restrictions and requirements for donating food. 

Use of technology to reduce food waste 

The participants indicated that they do not have a technology that helps them to track the food waste or assist them to reduce the food waste. They said that is the store could invest in technology it will make it easier for them to reduce food wastage. 

They also indicated that the store does not use reduce, reuse and recycle food waste.

The campaign targets to involve all the actors along the food supply chain, such as policy-makers, to reduce food losses and waste globally (UNFAO website, 2013). This will help the store to gain more knowledge on how to reduce food waste
