Slaughterhouses to use animal by-products as fuel for electricity production
by Mike Adams, the Health Ranger, NaturalNews Editor
The technologies of pyrolosis and gasification are now being used to produce electricity from animal waste. Rather than incinerating or rendering the by-products, which drive up production costs, using the unused waste to produce power will actually keep food production costs down. In fact, some are saying that every slaughterhouse could save on power thanks to this new method. In order to produce electricity, the animal by-products are shredded, dried and thermally treated to produce combustible gas. This gas is then used to provide power for the rest of the slaughterhouse. In fact, since the gas is burned in an oxygen-free environment, it is considered to be renewable energy.
11/04/2005 - A poultry production plant believes it will be able to generate all the electricity it needs from animal by-products to run its business and also provide a 2MW surplus to sell on, writes Anthony Fletcher.
"Nobody has put all these parts together before, but we thought why can't we do it at our plant," said development engineer Bob Waterson.
The by-products of poultry and other meat have to be disposed of through rendering and incineration, which increases production costs.
Faced with this Banham has developed and patented plans for a plant where the by-products are shredded, dried and then subjected to thermal treatment under contained conditions to produce a combustible gas.
This can then be used to power the continuing process, run a deodorising unit and fuel an electricity generator.
Food manufacturers are increasingly looking at new means of powering their factories and plants.
There is a great deal of legislative pressure on plant managers to cut down on emissions and waste, and Banham's solution is one of several new ideas that could move the industry towards renewable means of power.
For example, a hydrogen generation plant is currently being built in Offstein for major German confectionery processor S�dzucker.
The plant, which is based on the process of steam reforming from natural gas, will have a capacity of 900 Nm 3 /h hydrogen.
"We're drying the innards which come out of an abattoir and burning it in an oxygen free environment," said Waterson.
The company is already very concerned about the smells created by its business and its power project, and has spent �1.5 million on a program of odour control.
The Banham project is backed by the CRed carbon reduction campaign, the National Farmers Union, the poultry industry and Environment Agency.
