Applications and Environmental Benefits
The Maltin® System can be used to:
- treat organic waste
- convert specially grown crops into biogas
- generate biogas
- upgrade biogas to biomethane for vehicle fuel
- create clean fertiliser and soil conditioner
- create food quality or solvent quality renewable carbon dioxide gas
- create renewable materials such as wood substitutes which are so much better than MDF
Organic wastes can include:
- any biomass, anything which has ever grown
- bacteria do not have teeth, so the more liquid a feedstock, the better it is suited to the digestion process
- where the feedstock is not of a suitable viscosity, pre-treatment is necessary. The Maltin® System includes a high pressure low energy autoclave type pre treatment to ensure that the feedstock is suitably conditioned
- woody substances are not suitable for the Maltin® System
Biogas
Biogas is the name given to the mixture of gases formed during the anaerobic digestion of organic wastes. Biogas consists of methane (c70%) and carbon dioxide (c30%), water vapour, and other impurities and trace gases such as hydrogen sulphide. It can be used in boilers for heating and in stationary engines to generate electricity, but it is not suitable as a vehicle fuel.
It can be used:
- to generate electricity
- for upgrading to biomethane where its uses are the same as those for natural gas
Biomethane
- can be used for heating, cooling, as a source of chemicals, fertilisers or hydrogen, or as a vehicle fuel
Clean fertiliser
- the digestate can be separated into a solid soil conditioner and a liquid fertiliser. The solid conditioner improves impoverished soil structure
