With oil and gas scarcity becoming a reality, it is increasingly valuable to produce your own renewable energy using a profitable system that can pay for itself remarkably quickly. Depending on your circumstances, you may be able to save on your electricity and heating bills, reduce waste disposal costs, run your own vehicle fleet on gas and earn money from the outputs. Your production of electricity can even qualify for double ROCS ("Renewables Obligation Certificates").

The patented Maltin® System is ideal for:

• * Waste management for local authorities
• * Agriculture, particularly cattle, pig and chicken farms
• * Manufacturers who are substantial users of energy
• * Food retailers and manufacturers who have organic waste streams, including the dairy and meat industries and
• * Community and social uses, such as eco-friendly home builders and the Transition Towns Network
• * Renewable energy providers

At present there are large quantities of bio-waste from farming, food processing and municipal sources that are being disposed of at significant cost. Producers of waste have to pay the waste processors to accept materials, with costs rising rapidly as landfill taxes increase every year. Currently much of this waste is composted or sent to landfill, where it rots, emitting biogas, primarily carbon dioxide and methane.

Anaerobic digestion captures this biogas. After due processing, the methane can be used for such purposes as:

• * generating electricity: unlike solar and wind power, methane is available 24 hours each day
• * cooking and heating (it is similar to "natural gas")
• * transport: car and truck engines can be converted to run on methane

Except for wood, hair and bone, almost any organic material is commercially viable for anaerobic digestion. Possible commercial feedstocks include:

• * Cattle and pig slurry
• * Crops (such as maize or algae) grown for the purposes of renewable energy production
• * Food wastes from agriculture, retail out-dated stocks and sorted-at-source municipal collections
• * Abattoir waste, such as blood and offal
• * Lactose products, from the dairy industry, including the waste from cheese manufacturers
• * Liquid by-products of brewing and distilling
• * Glycerol, which is a waste product of the manufacture of bio-diesel
