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.

Using autoclave technology to clean up shellfish waste

Executive summary
Shellfish waste is a major financial and operational burden to the seafood processing industry. Current estimates show that around 63,000 tonnes of shellfish waste is sent for disposal each year at a cost of almost £3,000,000. 
In theory there are many uses for shell, but to date there is no one solution to treating and subsequently using these materials as by-products. Most processors rely on disposal outlets costing up to £150 per tonne of waste. 
Shellfish processors want simple, local, cost-effective solutions for managing shellfish waste. Equally they want to yield a shell that is completely free of flesh and malodour, so they can develop secondary markets for clean shell. The extent of treatment depends on the how the shell is ultimately going to be used. 
Autoclave technology has been identified as a potential solution for shellfish waste treatment. The technique produces sterile, clean, free of flesh shell that could be suitable for a wide range of applications. 
Autoclaving may be considered as a versatile, flexible treatment for difficult to handle food by-products and wastes that are expensive to dispose of. Read More
