ASSESSMENT OF THE POTENTIALS OF WASTE TO WEALTH

ASSESSMENT OF THE POTENTIALS OF WASTE COLLECTION TO WEALTH

Abstract

Municipal solid waste collection, re-use, and recycling have multiple socio-economic and environmental benefits that have not been adequately examined in Zaria, Kaduna State, Nigeria. The objectives of this research are to: examine the socio-economic and demographic characteristics of waste management entrepreneurs; identify the sources and destinations of recyclable municipal solid waste; analyze the number of waste materials (metal scraps, plastics, and cans) recovered, reused and transported for recycling; identify the type of uses recyclable materials are put into in the study area and examine the socioeconomic benefit of waste re-use and recycling.

A total of 252 scrap metal/plastic collectors, scavengers, and artisanal recyclers were studied using purposive and snowball sampling techniques. Tables, percentages, charts and multiple linear regression techniques were used for the analysis. The results showed that the majority of the waste collectors within the twelve localities of Zaria were less than 20 years old. Generally, the low educational level of the respondents indicates that formal educational qualification is not a major determinant of being an actor in this type of business… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

waste collection

INTRODUCTION

Background of the Study

The term waste has a different meaning for different people. In general, waste is unwanted for the person who discards it; a product or material that does not have a value anymore for the first user and is therefore thrown away. But unwanted is subjective and the waste could have value for another person in a different circumstance, or even in a different culture (Van de Klundert and Justine, 2001).

There are many large industries that operate primarily or exclusively using waste materials such as paper and metals as their industrial raw materials. In the context of Integrated Solid Waste Management (ISWM), waste is regarded both as valueless and as a useful material providing a potential source of income. This real value of waste in many low-and middle-income countries (developing countries) is confirmed by the huge informal sector that lives on waste collection and recovery (Van de Klundert and Justine, 2001)… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

Statement of the Research Problem

In the pursuit of sustainable waste management, the prevention of waste generation is the first priority, followed by waste recovery and safe disposal of waste on the hierarchy of principles for waste management (Figure 1.1). These principles need to be put in practice through joint waste prevention and management measures if growing environmental degradation is to be avoided.

For example, the use of valuable land for waste disposal, the release of harmful substances from landfills and waste transports into air, soil and water… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

LITERATURE REVIEW

Conceptual Issues

  • Scavenging

A waste picker is a person who collects reusable or recyclable materials discarded by others to sell or for personal utilization. Many terms are used to refer to people who salvage recyclables from the waste stream for sale or personal utilization.

These terms include informal resource recoverer, salvager, reclaimer, waste picker, recycler, and scavenger. Although the term scavenger is also commonly used, but many waste pickers find it demeaning due to the implied comparison  with  animals  (Samson,  2008)… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

  • Re-use

Re-use is a process by which discarded materials like plastic bottles, sachet water bags, glass, paper, woody furniture, scrap metals, etc. in their original form are utilized or sold to other users who need them. In other words, re-use is simply using materials for something other than the purpose for which they were originally designed (Bill, 2009). Re-use can be a creative process for using an item rather than throwing it away… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

Conceptual Framework

There is no over-arching approach or single solution identified that has completely answered the question of what to do with solid waste both in developed and developing countries. The attitudes of people in different countries vary regarding waste management practice.

The diversity of communities and their waste is one reason why no single approach to waste management has been accepted as “the best” method. Since there is no preferred method, every community must create its own “best approach” in dealing with its waste. However, all communities have the same alternatives (Palczynski and Scotia, 2002)… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

RESULTS FINDINGS AND DISCUSSIONS

  • Socio-Economic and Demographic Characteristics of Respondents

A total number of 252 solid waste collectors were involved in the study. Their socio-economic characteristics have inference on solid waste collection and were discussed under age, gender, educational and marital categories and religion. Other issues are income and ethnic composition.

  • Age of respondents

The study established that the majority of the waste collectors (engaged inn waste collection), about 46.4% within the twelve localities of Zaria, were less than 20 years old. Those between 21-30 years account for 34.5% while the least is 1.2% which covers 60 years and above. About 10.3%, 5.6%, 2.0%, are between 31-40 years, 41-50 years, and 51 – 60 year respectively. While all age groups are represented, the majority are youths, accounting for nearly half of the sampled population (Table 4.1).

  • Sex of respondents

The survey shows that 82.9% of the respondents who were males mostly involved in all waste activities (scrap metal and plastic bottle collection, scavenging and artisanal recycling). Furthermore, about 17.1% of the respondents were females that engaged in plastic bottle collection and cans collection. None of the women was involved in scrap metal collection and artisanal recycling… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

WASTE COLLECTION, REUSE AND RECYCLING

  • Sources of waste

Table 4.3 shows that 71.8% of waste collectors (engaged in waste collection) collect from multiple sources comprising households, institutions, landfill/dumpsites, restaurants etc compared to single sourcing of usable materials. Among the single sources, however, 15.1%, 10.7% and 2.4% respectively source from institutions, restaurants and households.

Using multiple sources by the scavengers, artisanal recyclers, plastic bottle and scrap metal collectors provide a variety and large quantity of recyclable materials which improve their income. It is important to note that, especially in institutions or households, scavengers purchase valuable waste from the owners; this is however based on weighing the recyclables to know the exact quantity (see Plate I and II).

But in the words  of  some  of  the  respondents  ― negotiation  at  times  does  exist  depending  on  the  quantity seen with the eye and not on measurement using weighing balance‖. The waste generated can be ascribed to the urban standard of living in the 12 localities sampled. Generally, manufactured products in iron, aluminum and plastic packaging are affordable and consumed by residents in the areas leading to waste materials.

CHALLENGES IN WASTE MANAGEMENT ACTIVITIES

All the respondents claimed that the government has not in any way come to their aid in terms of provision of a functional recycling plant in Zaria; trucks that will convey the valuable materials to the required destination at a subsidized rate; protectors especially to scavengers or even pay every individual involved in waste management for keeping the environment clean… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

CONCLUSION AND RECOMMENDATIONS

Conclusion

By adopting the wealth aspect from waste collection or treating solid wastes as resources, in terms of waste management strategy has effectively become not only a service but an instrument for alleviating poverty. The government should not only conceive waste management as a means of service delivery but a war against poverty and a poor living environment.

The future prospect of scrap metal/plastic collection, scavenging, and artisanal recycling is envisaged to be prosperous and can offer livelihood opportunities for poor people if the process of the collection remains unaltered… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
