Q: What is your product?
The Fosco Design Associates’ method of processing and recycling domestic and other waste to produce electrical and heat power from the paper and plastics residue. Less than 20% of the waste goes to landfill.
Q: How does it work?
The basis of our system is a rotary heated autoclave that uses hot oil, heating the tank and the existing moisture content of the input waste instead of putting raw steam into the vessel.
This sterilises the waste, breaking it down into its constituent parts, and reducing the moisture content suitable for specific waste parts to be used in a gasifier to produce electrical power that can be sold to the grid.
Q: Where would it ideally be used?
Local to the collection area, reducing the high cost of transporting compressed waste to centralised waste collection centres and landfill.
Q: What benefits does it offer?
Clean, sterilised waste, which can be sorted and sold on as feedstock at premium rates.
A typical cost for a plant that can process 50,000 tonnes a year would be around £4,000,000 supplied and commissioned. This plant would produce approximately 30,000 MW a year of electrical power.
Q Any savings?
Many of the sorted parts that are clean and sterilised in the process have a sales value. The Fosco autoclave system uses only 30% of the power to process the waste as that required by a typical steam autoclave.
Q: What about maintenance?
Low maintenance costs are an advantage of the system, and can be in-house or contract.
Q: What is its lifespan?
The autoclave would be expected to exceed 25 years in service with preventive maintenance. The associated hydraulics will be in excess of five years between major maintenance undertakings.
Q: How is it future-proofed?
Changes in legislation will be an advantage in that other waste streams can be used as a profitable process. With plastic packaging being replaced with paper products, Fosco is able to increase efficiency with less going to landfill.
Q: Any future applications?
Following testing of a prototype, Fosco is visualising the other waste streams that can be processed successfully.
