Smart Bin Electric Generator is a zero-waste solution offering the most efficient waste-management in domestic homes, institutions, hospitals, and factories by turning waste to energy.

 

As with most municipalities, garbage is a menace that without an effective waste management system in place, can cause a diverse range of problems: pollution, spread of water and airborne diseases, and an environmental 'eyesore.'

The two major cities used as case study is Nairobi and Mombasa in Kenya. In Nairobi, with a total population of over 4 million people, total waste generated in a day is about 2000 tonnes of solid waste. Only 80% of the daily generated waste is collected with almost 500 tonnes uncollected according to a report by the National Environmental Committee. On the other hand in Mombasa, a city with a total population of over 1 million people, the total waste collocation in a day is about 2500 tonnes with only 65% collected everyday. About 850 tonnes of waste goes uncollected.

It is clear that a majority of the waste collected everyday in both cities, on average 60% make up organic waste. Based on waste composition by residential typology (Joshua Palfreman, 2015), it is clear that the hospitality sector produces 77%, Mid-income areas 72%, Low-income areas 72%, and commercial sector 68% organic of the their total waste.

The collected waste end up in dump sites like Dandora in Nairobi and Mwakirunge in Mombasa. This waste is burnt hence polluting the environment and a majority of the unburnt piles up to further increase the pollution and spread of diseases. Scavengers are always at risk of contracting these diseases as well as the people living in the cities (water and airborne diseases) and the marine marine biomass when chemical compounds leech into oceans.

It is in an effort to address this problem when I came up with the zero-waste solution - The SMART BIN ELECTRIC GENERATOR - that is a technological innovation capable of capturing waste from the point of generation. This innovation sorts and separates garbage into recyclables, inorganics, and organics. Organic matter is converted to a fuel gas for electricity generation. The inorganic matter is turned to slug which can be sold as construction material(s). The competitive advantage of this innovation is that nothing goes to waste (zero-waste) - everything is processed to valuable products - and is the cleanest technology compared to the alternatives in the sector (those using thermochemical processes). It handles all the types of waste and is very scalable.
