Waste Autoclaves

AeroThermal's autoclave is a pressure vessel that steam treats its contents at a constant temperature and pressure, serving to sterilise, clean, break-down lignin structures and reduce waste volume by approximately 60%. Then, by applying a secondary process the true added value of the autoclave can be realised. These qualities can not only serve to increase landfill diversion rates, but if the process by-product, cellulose floc, is used to its full advantage, clean, green energy can be derived from waste.

Gasification

The EnviroThermal fixed bed gasifier is an innovative design that utilises a revolutionary multidirectional airflow. The system is currently being rigorously tested under University conditions and a small demonstration prototype will soon be available in Poole, Dorset.

Anaerobic Digestion

Anaerobic Digestion (AD) is the preferred stabilisation process for the treatment of wastewater sludge and organic wastes. The process provides volume and mass reduction and delivers valuable renewable energy with biogas production. Anaerobic digestion is a simple process that can greatly reduce the amount of organic matter that might otherwise be destined for landfill or burnt in an incinerator.

AAD
South West

British engineering company AeroThermal Group Ltd together with 4Recycling Ltd is proposing to develop a sustainable waste and resource treatment facility at the site of Imerys Minerals Ltd at Lee Moor, South Devon. The facility will use autoclave and The AeroThermal Group Ltd's proprietary Advanced Anaerobic Digestion (AAD) technology to generate 3MW of renewable (green) electricity. Recyclable materials will also be recovered from the waste stream and the stable digestate, a by-product of the AAD process, will be used to help restore parts of the adjoining Imerys Minerals Ltd Lee Moor China Clay workings.

Fourth waste scheme

ANOTHER waste treatment plant, which turns rubbish into methane gas, could be built near Ivybridge.
AAD (South West) Ltd is proposing an alternative waste and resource treatment facility.
It is the fourth waste treatment facility to be planned for the area with the Devon Waste Partnership proposing an incinerator at Devonport, Viridor hoping to build an incinerator at New England Quarry, near Lee Mill, and SUST-N, a local company, trying to find a greener waste solution with a Material Recovery Facility.
This fourth proposal is to develop a sustainable waste and resource treatment facility at the site of Imerys Minerals Ltd at Lee Moor.
The AeroThermal Group Ltd is proposing to construct an Advanced Anaerobic Digestion facility, which incorporates autoclave and anaerobic digestion.
This AAD plant will be a modern waste treatment processing facility that separates out materials for recycling, generates energy, and produces a soil conditioner. The compost-like material produced by the process will be used at the nearby Imerys Minerals Ltd Lee Moor China Clay workings as part of their ongoing restoration programme.
Commenting on the proposal, the AeroThermal Groups Ltd’s Commercial Director, Tristan Lloyd-Baker, said: ‘Our £9 million investment will create 22 long-term, skilled jobs for local people. In addition the facility will divert up to 75,000 tonnes of waste from landfill every year thereby avoiding harmful methane emissions and providing a facility to enable local businesses to maximise landfill diversion.’
