We are members of the Hampshire Woodfuel Cooperative which enables us to ensure security of supply.
Incoming wood waste which is unsuitable for either logs or compost is chipped for use in biomass boilers.
We normally have a stock of G50 chip, which we can deliver to end users in smaller or larger quantities (5 to 100 cubic metres per load). As a fuel, woodchip biomass is competitive with natural gas, and typical applications are heating small groups of houses, large individual houses, schools or glasshouses, where mains gas is not available. The Renewable Heat Incentive (RHI) is making this a highly attractive option.
The chip can also be used as a degradable surface for cars, horses or runners, or as a cheap substitute for bark mulch.
We also produce G30 grade woodchip, but lack of storage space means we do not always have stock available. We are working on this issue. The designations G50 and G30 refer to the ‘old’ ONORM standard M7 133. The current BS EN 14961-4:2011 standard refers to P45 and P16 grades which are essentially similar. What matters is that the chip you specify matches the certification of your boiler, in order not to breach your contract with Ofgem (assuming you are claiming RHI payments).
Biomass boilers vary in their tolerance of wet fuel, but most do not run well on chip with a moisture content higher that 30 percent. The maritime UK climate can be quite challenging when trying to produce naturally dried chip with a moisture content below 30%. Our recently installed Lauber drying system (www.lauber-holztrockner.de) which is powered by a biomass boiler, enables us to supply consistently dry chip.
