Solid and E-Waste Management
SectorMost major industry classification systems use sources of revenue as their basis for classifying companies into specific sectors, subsectors and industries. In order to group like companies based on their sustainability-related risks and opportunities, SASB created the Sustainable Industry Classification System® (SICS®) and the classification of sectors, subsectors and industries in the SDG Investor Platform is based on SICS.
Waste Management
Business Model Description

Develop and operate commercial dumpsites for the collection, storage and utilization of solid and e-waste from residential, commercial and industrial sources utilizing modern equipment, such as self-loading trucks, mixers and sorters, through a public-private partnership model. Recycling activities accompany waste disposal processes with possibility of biogas or energy production. The public actor invests in infrastructure, such as land, systems and logistics for collection, as well as sorting and recycling the waste. The private actor builds, operates and manages recycling plants and systems for reuse, making a profit from the provision of service and sale of recycled and reused material.

Expected Impact

Minimize health hazards associated with uncollected waste and move towards a circular economy with efficient and sustainable resource use.

Case Study: Chanzi reduces organic waste and provides an affordable source of animal protein
Chanzi, a GSIV Tanzania finalist, aims to drastically reduce Tanzania's organic waste while providing an affordable source of animal protein to livestock. By doing so, the company contributes to reducing the animal feed industries’ over-dependence on fish and soyabean as protein source for animal feed. Chanzi collects organic waste from households, farmers and industries and feeds the waste to larvae of Black Soldier Flies (BSF), an insect native to Tanzania. BSF are used as raw material to produce nutritious protein animal feed whereas its frass along with the remainder of organic waste is processed into nutrients and mineral-dense fertilizer.
