CW2WRAD is adopting the use of advanced gasification in the conversion of MSW.
Microwave plasma torches, either 2.45GHz or 9.15GHz, produce microwaves which are shaped within a waveguide to produce an electromagnetic field through which a gas flows, charging the gas and producing plasma. A swirl gas (often air) is used to insulate the gas outlet from high temperatures and to help form the plasma jet. Input power ranges from 25kW to 300kW. Gas flow rate affects only plasma volume, plasma temperature is consistent at 4,500K which allows a microwave plasma torch to operate within a range of feedstock flow rates while maintaining a consistent reaction temperature.
Waste is introduced into the top of the reactor via a continuous process system which removes most of the oxygen. Preprocessing of the waste to increase surface area, generally to 5cm diameter particle size, is necessary; moisture content should be no more than 20%.
CW2WRAD engages in the production of slag from MSW. The process produces slag from inorganic material. One ton of average municipal solid waste will produce 440 pounds of slag; 20% of the waste’s original weight and 5% of the volume. Slag is a glassy, metal-rich material which is vitrified and non-leaching, meaning it is inert and does not absorb or release hazardous materials. Hazardous materials such as asbestos or coal fly ash can be converted into slag.
Slag exits the waste refinery in a molten form which can be directly processed using several methods:
Products from slag:
Production and Applications
One ton of waste is worth approximately $127 in revenue. If 100% of Nigeria’s daily waste if processed would produce $1 million in daily revenue. Shanghai produces the equivalent of almost $1 billion a year in MSW, which today is deposited in Shanghai’s single official Laogang landfill or one of the more than 1,000 unofficial landfills surrounding the city. Revenue could be higher if the slag is used to produce higher value items such as foam insulation, a method adopted by one such project in China.

CW2WRAD elucidates about the use of plastic in civil construction. The components used by CW2WRAD include everything from plastic screws and hangers to bigger plastic parts that are used in decoration, electric wiring, flooring, wall covering and waterproofing. Plastic use in road construction that have shown same hope in terms of using plastic waste in road construction. i.e. plastic roads. Plastic roads mainly use plastic carry bags, disposable cups and PET bottles that are collected from garbage dumps as important ingredients of the construction materials. By using plastic waste as a modifier, we can reduce the quantity of cement and sand by their weight, hence decreasing the overall cost of construction.
Recycling and Upcycling
In a world already drowning in plastics, CW2WRAD is eliminating waste plastics and recycling single-use hangers. At our lab, we transfer knowledge to participants enabling them to manufacture a hanger composed of 80 percent plastic litter harvested from rivers and land.
