Viable WtE technologies for Sub-Saharan Africa.
We partner with firms that have developed commercially robust WtE technologies.
The technology platforms deployed in our projects are matched to the type and availability of feedstock, budget, subsidies, risk appetite, environmental and social regulation, policy objectives and financing availability.
Gasification.
Using a controlled amount of oxygen and/or steam, gasification is a combustion-less process that converts organic and inorganic feedstock into carbon monoxide, hydrogen and carbon dioxide using temperatures over 800°C. The hydrogen can be captured and burnt or used for electrolysis through a fuel cell.
Anaerobic Digestion.
The vast majority of organic waste ends up in some form of a landfill. Anaerobic digestion plants convert the biogenic portion of organic waste into renewable natural gas. This can then be burnt to produce heat, electricity and fertiliser. The high moisture content of organic waste also enables clean water to be extracted.
Incineration.
Using a combustion process, incineration takes varied waste streams, often municipal waste, and converts it into hot gas and ash, reducing its volume by up to 90% and its weight by around 30%.
Pyrolysis.
Undertaken in the absence of air and oxygen, pyrolysis uses an indirect source of heat to change the chemical composition of both organic and inorganic feedstocks, separating the feedstock into different molecules.
Depolymerisation.
Mimicking the natural geological processes used in the production of fossil fuels, hydrolysis pyrolysis converts complex organic materials into light crude oil.
