ABSTRACT
Products that are made from recycled materials or are sustainably produced are becoming more common and popular globally as people become more environmentally aware. However, these products are often expensive or not widely available. In developing countries, additional obstacles to adoption of such products are lack of awareness and affordability. In this study, I investigated public perceptions of, and willingness to buy, products made from recycled materials in Yola-Jimeta, northeastern Nigeria. Using a structured questionnaire, I interviewed 175 adult shoppers. Using cross-tabulations and logistic regression modeling, I evaluated the influence of demographic factors and level of environmental concern on how willing shoppers were to buy and pay more for three products (bag, basket, and mat) made from plastic bag waste. I also evaluated the role of an educational flyer in affecting public willingness to buy or pay more for these products. Household income was the only significant predictor of customers’ willingness to buy. People from wealthier households were more likely to buy environmentally friendly products even if they cost more. The flyer had a positive impact on
vii
respondents’ willingness to buy. This outcome supported my hypothesis that increased environmental awareness increases shoppers’ willingness to buy environmentally friendly products. However, only 49% of respondents in this study were willing to pay more; therefore, such increased awareness may not be enough to overcome financial obstacles. I recommend the sellers of the products carefully consider price and the socioeconomics of the region where the products are sold, as well as incorporate educational materials or programs into their marketing schemes.

CHAPTER 1
INTRODUCTION
Waste production has been an inevitable problem in the history of mankind. As human populations continue to grow, so does the production of waste. Waste production increases faster than the rate of urbanization. Every year, 1.3 billion tons of solid waste is produced globally (Hoornweg & Bhada-Tata, 2012). Waste production is predicted to increase to 2.2 billion tons by 2025 and more than double in low-income countries in the next 20 years (Hoornweg & Bhada-Tata, 2012). In the United States alone, about 250 million tons of trash is produced every year (United States Environmental Protection Agency, 2010).
Waste production increases with a rise in a country’s standard of living. As the economic wealth of a country increases, the country’s consumption also increases, which results in the potential increase in the amount of waste produced (Achankeng, 2003). For example, a research conducted in India showed an increase of 49% in the country’s population resulted in an increase of 67% waste production (UNEP, 2001). There are substantial variations in the amount of waste generated between and within countries. More waste is produced in North America, particularly in the United States than in any other region (Figure 1). Waste generation is lower in rural areas than urban areas (Hoornweg & Bhada-Tata, 2012). This may be due to lower densities of people living in rural areas. More than half of the world’s population today live in cities, where waste generation is high.
2
By 2050, the population of people living in the cities will be as large as the entire human population in 2000. This population will eventually produce a large amount of waste. (Hoornweg & Bhada-Tata, 2012).
Waste Management Practices and Health Implications
The increase in the amount of waste produced will result in the need for a proper waste management technique. In the past, there were no standard waste management practices until the occurrence of some serious pollution incidents due to of improper waste management. As a result governments had to enforce regulatory frameworks that deal with the management of waste. The main waste disposal technique for some countries are landfilling and incineration (Giusti, 2009).

Landfilling involves the burying of waste in landfills, while incineration deals with burning of waste materials. Other waste management practices are composting of waste, reusing and recycling (Figure 2). As of 2014, about 136 million tons of the total 258 million tons of waste produced in the United States are landfilled. Some 89 million tons are recycled and composted while the remaining 33 million tons are incinerated (United States Environmental Protection Agency, 2014).
With the advent of science and technology, management of waste became more organized and focused (Giusti, 2009). Nevertheless, poor waste management led to serious environmental and health issues. Specifically, mismanagement of waste leads to water, air and land contamination, which eventually affect public health (Giusti, 2009). Environmental problems include water and air pollution. Water is
4
contaminated by leachate, which comes as a result of water percolation through the waste deposit. Air is contaminated through burning of waste particles. Also, solid waste particles that are not properly disposed of serve as breeding sites for insects, promoting air and water-borne diseases (Alam, Chowdhury, Hasan, Karanjit, & Shrestha, 2008).
Diseases such as cholera are contracted as a result of contamination of water by some pathogens (Giusti, 2009). Pathogens are disease-causing agents. Health issues are connected to the practices of handling and disposal of waste. This involves recycling activities and exposure to emissions caused by incineration and the odor from landfills. Exposure to emissions from incinerators is mostly due to inhalation and in case of water, it occurs as a result of consumption of water that is contaminated by leachate (Giusti, 2009). In developing countries, waste is mostly dumped in lowland areas, and there are no imposed regulations for waste disposal. Solid waste may not be separated from infectious and toxic wastes that are harmful to waste scavengers and the environment (Alam et al., 2008).
Specifically, landfills affect human health by causing congenital malformations. Incineration on the other hand increases the risk of developing a group of blood cancer that evolved from lymphocytes known as non-Hodgkin’s lymphomas and sarcomas. It also leads to poor air quality and can cause acid rainfall. Composting of waste as a waste management practice exposed workers to respiratory diseases (Giusti, 2009). None of these methods, though, helped reduce the amount of waste humans keep producing. This led people to think about how to manage waste and if
5
there was any other way to treat or use waste. This is how the recycling and reuse of waste started (Skinner, 1993).
There are several factors that affect waste management practice. According to (Guerrero, Maas, & Hogland, 2013), there are several factors that affect waste production, separation and management in developing countries. Some of these factors include; lack of knowledge on technologies to use for waste management, lack of equipment, and absence of decision makers. Also, public awareness influences individual behavior towards waste management practices. Knowing the consequences of waste mismanagement to the environment and individual health influence people’s practice of proper waste management (Guerrero et al., 2013). The more environmentally aware an individual is, the more likely he is to properly dispose of household waste, separate toxic from solid waste, avoid littering, and pay for waste management services (Imam, Mohammed, Wilson, & Cheeseman, 2008). Educating people about the importance and significance of waste management increases their level of participation in waste management programs (Nnorom, Ohakwe, & Osibanjo, 2009).
Generally, the condition of waste management practice in developing countries is very critical because it is not considered a priority. Water quality, lack of food, poor education, widespread of diseases are major problems in developing countries that make waste management not a major priority (Giusti, 2009). In contrast, several U.S. cities have already banned the use of packaging materials, particularly plastic bags, as have some countries in Africa, such as Kenya recently in 2017, Morocco in 2016, and Rwanda in 2008. Kenya has severe penalties for violators (BBC, 2017). This is
6
done in order to reduce the amount of waste generated. Plastic bags are believed to contribute heavily to waste production (Skinner, 1993).
The problem with some of the waste management techniques is not just limited to public health consequences but other financial constraints. Landfilling as a technique needs to be operated on a large scale. This requires financial input mostly from the government. Also, the cost of completely cleaning up a dumpsite is a burden on a nation’s economy. Even though cleaning of dumpsite provides business opportunities between countries, there is a need to identify the environmental consequences and costs of waste management system. The more productive technique to consider for waste management is recycling (Skinner, 1993). It is more reliable than the aforementioned techniques because it involves converting what is considered useless into useful and valuable items (Cooper, 2008).
Recycling
Recycling is the environmental reprocessing of disposed waste. Recycling is more than just a way to transform waste to raw materials, but also a way of reusing old materials into new forms through maintenance and repair. Recycling is not just limited to plastic bags and plastic containers. Paper, metals and glass can also be recycled. Recycling is done as a means of reusing items through extending their lives in another useful form. It is considered an easy way to maintain already existing things (Werrett, 2013). Globally, recycling is not done on a large scale. From the 250 million tons of trash that is produced in the United States, only 65 million tons is recycled (United States Environmental Protection Agency, 2010).
7
In developed countries, recycling involves industrialized activities and is considered as part of the daily life of each citizen. Thus, in these types of countries, research on recycling considers technical applications of models and tools. Socio-economic factors that affect recycling in the developed world include education, income, consumption patterns, gender, and age (Troschinetz & Mihelcic, 2009).
In contrast, developing countries have only few researches that focus on recycling. Most of these few researches were done in China and Mexico. These researches considered belief as one of the factors that influence recycling and other environmental behaviors. This entails the belief and understanding of reasons to recycle. Both Mexico and China are on the transition state to become developed countries. Other factors that influences recycling in developing countries are government policy, a country’s finance, knowledge of solid waste management and land availability (Troschinetz & Mihelcic, 2009). In a similar study that was conducted in 2012 on 22 developing countries from 4 different continents, findings showed that citizens that get information on the benefits of recycling are more likely to recycle waste materials (Guerrero et al., 2013).
Recycling has an advantage to the environment over other waste management techniques. Proponents of recycling opined that using products that are made from recycled materials has a benefit of reducing environmental pollution caused by litter. Another advantage is that recycling preserves biodiversity; by recycling and not using landfills, the land can be used for more productive means rather than just filling it with waste (Black, 1995) .

Consumer preferences toward green products
Today, most people are concerned about what they use in the environment because they care about the quality of life of future generation (Khan & Mohsin, 2017). This is unlike the way the ancestors have lived (Khan & Mohsin, 2017). For consumers who are concerned with the negative impacts of products on the environment, they consider it a good idea to use “green” or environmentally friendly, products (Bhatia & Jain, 2013). Green products are those that are presumed to be environmentally safe. Most examples of green products are domestic materials that were made from discarded papers or plastics, recyclable packaging materials, cleansers made from biodegradable materials, pollution-free agents and energy-efficient light bulbs (Mainieri, Barnett, Valdero, Unipan, & Oskamp, 1997).
The major concern with the environmental consequences of not using green products is mostly due to climatic factors, environmental degradation, which give rise to global warming and the stratospheric ozone layer depletion. This eventually results to increasing air, land, and water pollution and subsequently the destruction of natural habitats (Khan & Mohsin, 2017). Therefore, using green products has an advantage of making the environment less polluted (Bhatia & Jain, 2013).
Since consumers are becoming more concerned about the consequences of what they consume and use to their health and the environment as well, they are beginning to change their attitudes and behavior towards their food and things they use (Biswas & Roy, 2015; Laroche, Bergeron, & Barbaro-Forleo, 2001). These concerns have increased the demand for products made by environmentally conscious firms. The goal of all sustainable production is to meet the needs of today without affecting the
9
environment’s ability to meet the needs for future generations (Forbes, Cohen, Cullen, Wratten, & Fountain, 2009). Companies are considering sustainable production as a competitive advantage (Bhaskaran, Polonsky, Cary, & Fernandez, 2006; Forbes et al., 2009; Mollá-Bauzá, Martinez-Carrasco, Martínez-Poveda, & Pérez, 2005).
In a study in New Zealand, environmentally sustainable wine was preferred by 75% of the respondents, whereas 5% of respondents had no preference for sustainably produced wine. According to the results, factors that influence consumer preferences to buying sustainable wine include proper labeling indicating that the wine is produced using environmentally sustainable techniques. Another significant factor are the environmental and health consequences of using the wine. Therefore, production of environmentally sustainable wines may yield a significant benefit in the market (Forbes et al., 2009).
Another study that was carried on women with children who shop regularly in supermarkets in London concluded that 80% of the women are likely to choose products they knew were produced by companies that use environmentally friendly practices. None of the women strongly disagreed when asked if they would choose sustainable products. The results of this study mentioned factors that affected consumer preferences to include trust in products, including exposure and product-marketing communication. Most female respondents in the study trust only well-known brands. Lack of exposure to green products and informing consumers about new and improved products that are environmentally friendly also affect consumer preferences (Pickett‐Baker & Ozaki, 2008).

Environmental attitudes and behaviors
Consumer attitudes, beliefs and values need to be considered when identifying factors that influence consumer’s purchase decision. Attitudes generally are the beliefs people have for a particular thing that incline people to behave in a particular way toward that thing (Weigel,1983, as cited in Mainieri et al., 1997). Consequently, people with positive attitudes toward environmental protection are more likely to support the use of environment-friendly materials. An important finding in the study of Laroche et al. (2001) confirms the relationship between attitudes and willingness to pay for green products. Customers that were willing to buy green products did not professed it as inconvenient to behave in an environmentally favorable manner while the reverse was true for customers that were not willing to buy green products (Laroche et al., 2001).
Demographic factors, such as age, gender, ethnicity, and educational status, may contribute to environmental attitudes and behavior. Traditionally, people that are young, well-educated, wealthy and based in cities were considered as the group that are more concerned about environment-related issues (Arbuthnot, 1977). This is not the case today. Today, women are more likely to be environmental advocates than men (Mainieri et al., 1997). This is because women are more likely to do most of the shopping for a household, which may make them more aware of environmentally friendly products. Women also recycle and participate in environmental issues more than men (Mainieri et al., 1997). Education and income may also be positively or negatively correlated with environmental attitudes. Therefore, depending on the society, demographics may not be great predictors of environmental concern and behavior (Mainieri et al., 1997).
11
In developing countries, environmental attitudes are considered a major factor to determine consumer perception on sustainable products and attitudes toward a green lifestyle. For example, in Nigeria, research concluded that willingness to participate in e-waste recycling was dependent on environmental awareness, individual concern about the environment, and willingness to support efforts to control environmental deterioration (Nnorom et al., 2009). Thus, for developing countries where environmental awareness may be low, the willingness of people to pay for waste management and green products is considered low compared to their willingness to pay for electricity and water bills (Nnorom et al., 2009).
Factors that affect purchase decision
Most studies have shown support for environmental protection, but it is yet to be concluded how much the public are willing to pay for the improvement of the environment. Consumers may be price-sensitive when it comes to buying more-expensive green products, despite their environmental concern (Mainieri et al., 1997). One of such studies concluded that among the 74% of the consumers that preferred environmental protection to economic growth, only few of them participated in environmental protection behaviors such as the recycling of bottles, cans, and newspapers. About 75% of the consumers claimed to pay more for green products, but only 14% of them bought products made from recycled materials. Despite their pro-environment concern, again only 16% of the consumers avoided companies that are considered anti-environment (Mainieri et al., 1997). Though many people claim to be environmentally concerned, their actions toward the environment may not support their convictions.
12
The major concern is that what most people say they are willing to pay for to buy recycled products will not be the same with what they end up paying for. Therefore, there is a need to better understand other factors that influence consumer buying behavior (Hamzaoui Essoussi & Linton, 2010).
According to the study conducted by Laroche et al. (2001) in a large North-American city, several factors contributed to the resident’s willingness to buy and pay more for sustainable products. The factors include demographics, environmental literacy, values, behaviors, and attitudes toward environmental issues. In this study, the most influential factors were demographics; specifically gender, marital status, and number of children. Married women with at least one child were more likely to pay more for sustainable products. This result may be attributed to the fact that women are more environmentally conscious than men. Their marital status also contributed because of their thought of how a ruined environment will affect their partners and children (Laroche et al., 2001).
Another important factor that influences purchase decision of green products is environmental awareness. Environmental awareness is important to consumer’s determination of what product to buy. This can be seen in the result of a study where absence of information about a remanufactured camera made participants value it less than its substitutes. The introduction of the environmental information about the remanufacturing process and environmental characteristics of the remanufactured camera as opposed to a conventional one, made the participants boycott the conventional camera and accept the remanufactured one. Even with the debriefing about the products, people were concerned about its quality as a remanufactured
13
product. Therefore, quality and price are two other main factors that affect consumer’s purchase decision. The challenge is for companies that make green products to consider high quality standards for their products. Accordingly, there should be proper labelling to enable consumers to know what product they are buying (Michaud & Llerena, 2010).
Consumers & green products in developing countries and Nigeria
There is a global concern in the population growth rate. This is because a growing population is always followed by growing needs. In developing countries, population growth rate has increased significantly. As the population continues to increase, there is a need to create new and big markets for products. Unlike in developed countries, people in developing countries are not aware of environmental problems and do not show concern for it (Yadav & Pathak, 2014).
In India, a study was conducted in 2013 on consumer perception toward green products. The result showed that consumers have a positive attitude towards green products but they are more concerned about the price and availability of such products. It was found that only a small percentage of people buy green products. It was then concluded that if marketers make consumers aware of the benefits of green products, consumers will be willing to pay more for green products than other traditional products (Bhatia & Jain, 2013).
Nigeria has the largest human population of any African country; thus, it represents a large and growing market for consumer goods. The country also suffers from widespread pollution and environmental degradation. The Nigerian government has
14
adopted sustainable development as part of the United Nations’ Sustainable Development Goals, which were launched at an international summit in 2015. Within Nigeria, businesses and organizations may promote sustainability in their own ways.
For example, in northeastern Nigeria, the American University of Nigeria (AUN), a private university, is involved in several projects promoting sustainability as part of its mission as Africa’s development university. In 2012, AUN became the first member from sub-Saharan Africa of the Association for the Advancement of Sustainability in Higher Education (AASHE). That same year the AUN Sustainability Office was established. The Office of Sustainability built nature trails, developed bottle-brick construction projects, planted trees, taught sustainable farming to poor rural farmers, and runs two programs that turn waste materials into consumer products while simultaneously supporting local women in the community.
Established in 2013, the first of these programs, called Waste-to-Wealth, helps women learn how to clean and sew products, such as handbags and floor mats, from used plastic bags, thus helping clean the environment while giving local women a source of income (AUN Office of Sustainability, 2013). In 2015, the second program, Creating-with-Threads, was established. In this program women use discarded materials from tailors to make products such as floor rugs, computer bags, and makeup cases (AUN Office of Sustainability, 2015).
Products made through these programs have been sold at exhibitions in Nigeria’s Federal Capital Territory, Abuja. The Sustainability Office also regularly organizes sales exhibitions at AUN to draw the attention of customers. However, the AUN
15
Sustainability Office is challenged to market these products to the wider Nigerian public, to help create more income for local women manufacturers and bring more women into the program.
Therefore, I investigated the Nigerian public’s perception of and willingness to buy products made from the Waste to Wealth program. I focused on the city region of Yola-Jimeta, Adamawa State, in northeastern Nigeria, where AUN is located. My aim was to identify factors, such as demographics, that may influence people’s interest in and willingness to buy these locally made green products. I also aimed to identify whether increased environmental awareness influences the public’s perceptions and willingness to buy the products.
