Plant manufacturer Weltec Biopower has signed two orders for agricultural biogas plant projects.
The Warwickshire company is currently building a 500kW plant for Stephen Carson’s agricultural enterprise near Strabane, Northern Ireland. It is set to feed in power by the summer. Low Farm in Sherburn, England, also has a 500kW biogas project built with Weltec technology.
In both plants, the upstream Multimix input system ensures optimum pre-treatment of the substrates. This means the operator can make use of inexpensive feedstock such as manure and grass.
The surface area of input materials is increased by effective shredding which optimises substrate/bacteria contact and boosts methane yield. Multimix also removes stones from feedstock, reduces the likelihood of layering within the digester and cuts the energy needed for digester mixing.
