The Gasplasma® process pushes the boundaries of waste to energy technology. It outperforms other solutions, both in environmental terms and on electrical efficiency. The innovative combination of established gasification and plasma conversion technologies allows for the highly efficient production of a very clean syngas, the essential component for efficient energy generation through gas engines or turbines and for other downstream applications.
APP’s Gasplasma® technology offers numerous unique benefits over conventional thermal treatment technologies.
Converting waste to a gas to generate electricity directly in gas engines, gas turbines or fuel cells dramatically improves energy conversion efficiency and maximises electrical output. The gas is also capable of being converted to liquid fuels, hydrogen or to substitute natural gas for distribution to homes and businesses in existing gas grids.
The Gasplasma® process enables almost complete landfill diversion and is complementary to recycling. It can be used in conjunction with existing recycling schemes and, after the removal of recyclates, takes waste that cannot be recycled and uses it to produce energy. The process produces a high value construction material called Plasmarok® that is recognised as a product not a waste. This removes any environmental, regulatory and commercial risks which are associated with concerns over the potential eco-toxicity of bottom ash produced by incinerators and other thermal processes.
A Gasplasma® plant processing 100,000 tonnes per annum of RDF is around 15 metres high, meaning that it can fit into a standard warehouse similar to the kind seen in edge of town business parks. Emissions from the plant are very low allowing for a stack of only some 10 metres above the height of the building. When producing fuels local emissions are negligible and no stack is required.
The low environmental impact means that a plant can be located, unobtrusively on the edge of a town, taking waste from that town and supplying power and heat in return – a local community solution to local waste management challenges and sustainable energy requirements. Situating a plant close to population centres has additional benefits such as reducing the carbon footprint of waste by cutting the distance over which it is transported. Moreover, locating plants close to heat users, whether industrial or domestic, further improves energy efficiency.
As most of the equipment is manufactured off-site and is modular, a plant can be built and installed in 18 months compared to 24-30 months for alternative technologies, which usually require a substantial amount of on-site fabrication work.
