Technologies
This project will focus on three possible technological solutions to the issue of waste management within Scotland:
· Anaerobic Digestion
· Bioethanol Production
· Incineration
This page provides a breif summary of the technologies. Further information can be assessed by clicking on the pictures of the next to the headings
Anaerobic Digestion
Anaerobic Digestion of waste is the breakdown of the biodegradable fraction of municipal waste by bacteria in a controlled environment. The process has several stages with several products the key product is methane. The released methane can be captured and used as a fuel to generate power or as a product for chemical industry.
Bioethanol Production
During bioethanol production the organic component of municipal waste is digested through various process into sugars which are then fermented to make bioethanol. Bioethanol can be used an alternative to conventional vehicle fuel reducing the demand placed on petroleum stocks.
Incineration
Incineration of waste is a process that can be used as a cource of heat and power. The waste is combusted in a central plant and the heat generated is used to create steam to drive turbines or as heat through a local heat network. Incineration can reduce the volume of waste sent to landfill by over 90% reducing the demand for land, however there are questions of public perception relating to health and environmental concerns.
