Companies were driven into recycling due to three main reasons: environmental, economic and social. All companies responded that the motivation for their involvement in solid waste recycling activities was based on environmental reasons, which came out to be 100%, economic reasons came out to be 86.6%; and only 20% of the companies reported social reasons. Therefore environmental and economic stood out as the main motives for recycling by companies.
Discussions with most participants, 100% of companies considered recycling to be environmentally driven. However, 100% of the companies who were physically recycling indicated that they were doing this for economic reasons. 4.2.
4 Extent of Involvement in Recycling Industry The extent of involvement of companies varied depending on their core activities in the recycling loop. According to EPA (2016), the recycling loop involves the following three major activities:• step 1-collection and processing,• step 2 manufacturing;• step 3 purchasing/selling of new products made from the recycled materials The loop is not considered complete without purchasing. These steps are repeated over and over again as the products are repeatedly recycled, thus companies aligned themselves with all or some of these activities. 4.2.4.
1 Extent of Involvement with regards to processesThe study was based on the assumption that companies are involved in the three steps mentioned above, but these activities could be further broken down into smaller activities as illustrated later on in this section.To establish the extent of involvement with regards to the processes, the following question was posed “What is the extent of your involvement in the industry in terms of collection, processing, manufacturing and purchasing and selling of new products?” Responses were as shown in the table 4.5.Table 4.5: Extent of Involvement with regards to the recycling processCompany Collection and Processing Manufacturing Purchasing/ selling Others/Promoting Total Activities Per Company Recovery and Collection Pre-processing Processing A ? ? ? 3B ? ? ? 3C ? ? 2D ? ? ? 2E ? ? 2F ? ? 2G ? ? 2H ? ? ? ? 4I ? 1J ? ? 2K ? ? 2L ? ? 2M ? 1N ? ? 2O ? 1Total Companies (%) 9 8 1 3 3 7 64 57 7 21 21 50 Source: Research DataThe extent of involvement of companies emerged into five categories: collection, pre-processing, processing, manufacturing, purchasing as summarized in Table 4.
5.The responses illustrate that all companies were involved though one of the participants had indicated during the interview that “There is no recycling here. We just collect and send the materials to South Africa.
” Majority of companies, 64% were involved with collection and pre-processing activities, the first step of the recycling loop; 21% of the companies were into manufacturing and selling of products respectively, while 50% were involved in other activities and 7% in processing of collected materials (7%).126.96.36.199 Extent of Involvement with regards to type of product materialsNot all solid waste materials were recyclable. Recycling of solid waste involves handling plastic, paper, glass, e-waste or scrap metal.
The residue after sorting recyclables was thrown to the landfills. To find out more, the researcher had to establish types and nature of recyclables that companies handled. In order to establish this, the following question was posed “Which type of recyclable raw materials do you deal with?” It came out that seven products material were being recycled as in Table 4.6Table 4.6 Product material handling per Company Company Plastic Paper Glass Cans Tires Scrap Metals e-waste Total ProductsA ? ? ? ? ? ? 6B ? 1C ? 1D ? 1E ? 1F ? ? ? 3G ? ? 2H ? ? ? ? 4I 0J ? 1K ? 1L ? ? 2M 0N O 0Total 8 2 4 4 3 1 Source: Research DataA total of eight (8) companies handled plastics, two (2) handled papers, one (1) company was involved in e-waste recycling and three (3) companies were recycling scrap metal.
Three (3) companies were not involved with any product material. These companies were not involved in physical recycling of materials but their roles were more of policy, regulation and supportive in nature. Only three (3) companies were handling more than 3 product material with 1 company handing almost all the products except e-waste. Respondents categorized these materials further as shown in Table 4.7.

Plastic was divided into two major categories of soft and hard plastic and the variety of types identified. Some of the respondents (Company A & D) further categorized their plastics into recycling symbols or codes as shown in Table 4.8.4.
2.4.3 Extent of involvement with regards to modes of collectionDifferent modes of collection were used and materials collected from different sources as well. The researcher also established how companies were able to source materials for recycling. The following question was posed; “Where do you get the recyclable materials and how?” a) Source of materialRecyclable materials were collected from different sources.
Table 4.9 shows sources of raw materials. Table 4.9: Sources of raw materials by company Sources of Products Company Household Institutions Commercial Industries Others Total SourcesA ? ? ? ? ? 5B ? 1C ? 1D ? ? 2E ? ? ? 3F ? 1G ? ? 2H ? ? ? ? 4I J ? ? ? ? 4K ? ? ? ? 4L ? 1M N ? ? ? ? ? 5Total 4 6 6 7 10 Source: Research DataFive (5) areas for material recovery were identified. Companies A and N Two collected their raw materials from all 5 sources, while five (5) companies indicated less than 2 sources. Ten (10) companies had other sources of material from farms, mines, construction site, ship wreck site, fisheries, resorts.Table 4.
9 also shows that companies were competing for the recyclable raw materials, with 7 companies collecting from industries, while only 4 companies were collecting from household. The fact that more companies are collecting from industries than residential areas may suggest that there are incentives given by industries than residential.b) Collection modesRecyclable raw materials were collected through different modes as shown in Table 4.10. Table 4.10: Collection Modes Collection Modes Source of CollectionKerb-side Door to doorDrop -Off or clear bag Systems Shopping centers, residential, open spaces etc.On- Site Landfill, industries, mines, schools, institutionsSource: Research DataTable 4.9 shows that three modes of collection were identified: Kerb-side (door to door), drop off centers (shopping centers; open spaces) and on site (landfill, industries, mines, farms, schools and institutions).
