Kedco have a system of converting waste to energy, the Kedco Green Energy Harvester. Since the beginning of the 21st centurary a new market has opened up for the use of biogas technology in the production of electrical and thermal energy from organic matter. The technology of ‘dry fermentation‘ can generate enery from communal and agricultural organic matter/waste.

Up until recently, biogas technology concentrated primarily on the ‘wet fermentation’ of agricultural and communal organic waste, while the recently patented Bekon dry fermentation process can produce methane from organic matter with a high content of dry matter. This kind of energy production is environmentally sound and cost effective, while also creating and securing employment.

Instead of disposing of organic matter from agriculture or communal waste in other ways, dry fermentation offers a means of turning it into a valuable resource and extracting the highest possible benifit from it (in the form of biogas, electricity, heat, compost and fertiliser). The high quality compost, which results from the process of dry fermentation, can be used as a valuable fertilizer for agricultural and horticultural purpose.

Advantages of Dry Fermentation

1. Additional income for waste disposers, municipalities, farmers

2. Generation of a direct source of income in rural areas through highly valuable end products (electricity, heat, compost). Additional advantages compared to wet fermentation systems in countries where water is a limited resource. Low maintenance requirements and robust technology, therefore particularly suitable for export. Potentially contribution to reducing fossil fuel consumption and thus to combating climate change.

3. Perfect Solutions for Governments with a waste management issue.

4. Utilization of presently unused high energy content substrates.

5. Compact design of plant.

6. Low maintenance and noise reduction costs, low investment costs for plant and mechanical devices

7. Few moving parts in the biogas plant itself, thus reducing the costs of wear and tear

8. Highly developed, modern, computer-controlled system

9. Low process energy consumption (less than 10% of the energy produced in the co-generation unit)

10. High, good quality gas yields

11. Possibility of modular expansion

Use of the wheel loaders and the front-end loaders to fill and empty the digesters, and therefore potential use of the available equipment

Simple process that allows a large variety of non-organic substances (sand, wood, plastic, etc.) in the substrate throughout the digesting process; interfering substances can be sieved out after digestion

No costly storage of the digested substrates, as with liquid substances; cheaper transport costs
