OUR WASTE-TO-ENERGY TECHNOLOGY
Converting waste to energy requires simpler technology than you might think. The process is based on the technique used to manufacture charcoal – namely the application of heat and the absence of oxygen – updated, adapted and refined for this thoroughly modern purpose.
Our technology is designed to utilise the waste being collected at the plant to create the heat required for the pyrolysis plant. This ability to use waste feedstock for our principle energy requirement means that the energy products we produce from the recycled waste are considered 100% renewable. Moreover, because we are not using energy sources such as gas or electricity for the heating process we can substantially cut our costs of operation and increase the amount of waste we are able to process overall – further increasing the revenue we collect from ‘gate fees’.
Pyrolysis is the high-temperature treatment of carbon-based materials in the absence of oxygen. No oxygen means no combustion, leading to the waste being broken down into it's chemical components. The residues can be in the form of gas and bio-coal.
Torrefaction is a type of pyrolysis, carried out at the lower end of the temperature range. Torrefaction converts biomass (waste wood) to bio-coal, a solid, dry, energy-dense material that is easy to store and transport.
- SMART DESIGN
- LOW ENVIRONMENTAL IMPACT
- FLEXIBLE USAGE
- Simple design with no unnecessary hardware or parts, constructed using a variety of known techniques
- Operating at a zero-pressure level, utilising many tried-and-tested safety features
- Low lifetime maintenance costs and maximum operational hours
LOW ENVIRONMENTAL IMPACT:
- Low profile and small footprint make it easy and inexpensive to locate plants around existing infrastructure and in areas with increased planning regulation
- The site is close to being 100% energy self-sufficient, powered by the system’s own feedstock
- Quiet, odourless operation
- Emissions that are cleaner than those from burning natural gas
- No by-products requiring disposal, qualifying for end-of-waste certification
- Our unique technology (under patent application) incorporates advanced features for the control of temperature
- Flexibility to use a variety of waste feedstocks, including hazardous and toxic materials
- Ability to deliver a range of products tailored to customer specifications
- Output capabilities include solid recovered fuel, bio-coal, liquid gas and syngas
SOLID RECOVERED FUEL (SRF)
SRFs are produced through a thermal drying process and are chiefly composed of non-hazardous waste, including paper, cardboard, wood and plastics, resulting from household and general industrial waste residues, making them a versatile energy source. They are used to power various heat treatment plants, including cement factories, kilns, heating plants and industrial furnaces, due to their high calorific value.
Bio-coal is made from biomass, wood waste produced by the timber and construction industries, which we then process through torrefaction. It has similar qualities to coal, while being significantly more environmentally friendly, with carbon savings of more than 80% and unlike coal and oil, it does not contain any sulphur, which is extremely harmful to the environment. It consequently enjoys high demand from the power industry.
SYNTHETIC GAS (SYNGAS)
REWS’ plants are designed to produce synthetic gas or ‘syngas’, comprised largely of hydrogen, carbon monoxide and methane, through a high-temperature pyrolysis process. Positioning us to take advantage of this rapidly growing market, within which there is a huge demand. Syngas is a cleaner alternative to natural gas and can be used in both domestic and industrial settings.
