The mechanical biological treatment (MBT) process used at New Earth’s residual waste treatment facilities takes residual household waste and separates out valuable recyclable materials from organic matter. Additionally, the process prepares a refuse-derived fuel (RDF) for use in renewable energy schemes. This fuel is produced in support of the principles of the waste hierarchy – recycling where suitable opportunities exist before the recovery of energy.
New Earth has developed modular technology to treat RDF using pyrolysis and gasification techniques. The resulting energy produced can be exported to the local distribution grid as renewable electricity and also provides the option of recovering heat from the process for use in nearby commercial applications, such as space heating or refrigeration (through the use of inverters).
The New Earth Advanced Thermal (NEAT) energy recovery technology, combined with New Earth’s MBT process, delivers an integrated, ‘closed-loop’ solution to dealing with waste – reducing landfill, enhancing recycling and generating renewable energy.
• Units can be banked together to create plants with various power outputs and capacity.
• The modular approach provides high operational availability and integration into existing infrastructure if required.
• The process generates heat for re-use in the process, as well as offering potential for heat supplies to suitable heat consumers.
• The technology can be positioned on site with waste treatment facilities or stand-alone close to the users of the energy.
