New legislation has been developed to introduce biomass sustainability requirements for the RHI scheme RHI plans for biomass sustainability report will be made on the biomass IMPROVEMENTS were made to used in the reporting year. the Renewable Heat Incentive (RHI), Applications for suppliers to be added back in May this year, but further to the BSL are open now, and only changes are planned to come into apply to wood fuel suppliers. Selfforce in spring 2015, visitors to suppliers can also register on the BSL Nextgen heard. but it is not compulsory. . Subject to parliamentary approval The BSL is now open to consumers the changes will apply from spring so they can search to find a BSL2015 for both existing and new approved supplier nearby. applicants. Ofgem senior manager Atika Ashraf Anyone receiving payments under said: “All participants are strongly the RHI and using wood as a fuel encouraged to start sourcing from source must obtain their wood from a BSL supplier in advance of the a sustainable supplier listed on the criteria coming into force.” Biomass Supplier List (BSL), in order For more details or to apply go to comply with the scheme. Wood fuel to: www.biomass-suppliers-list. suppliers should register on the BSL service.gov.uk if they supply fuel to anyone claiming RHI. To be approved on the BSL wood fuel suppliers need to selfreport quarterly to Ofgem on the sustainability of the fuel they are producing, and where applicable, an annual independent sustainability Meeting an increasing global demand for milk PROF Liam Sinclair of Harper Adams University focused on issues related to the future feeding of dairy cows against a backdrop of growing global demand for milk combined with environmental concerns and human dietary requirements. He said: “It is predicted world milk production will need to increase by almost 30 per cent on a global scale over the next decade. It seems likely some of the additional production will be achieved by housed herds which rely on bought-in feeds, such as cereals and their by-products, as well as proteins such as soyabean meal. “This, in turn, would increase demand and therefore prices. Dairy cow feed costs would also be pushed up because of competition for crops for biofuels. “This upturn in demand would have to be met using fewer resources particularly human-edible foodstuffs - and with a reduced impact on the environment. It would also have to be high quality, in terms of microbial content and its impact on human health, with coronary heart disease and cancer being the two main priorities.” One option to reduce farmers’ reliance on purchased feeds was to include home-grown protein forages in dairy diets, said Prof Sinclair. Recent studies at Harper Adams had shown lucerne could successfully replace maize/grass silage and grass silage-only diets, reducing the requirement for purchased protein. Potential Another area of research was looking at the potential for lowering the degradability of protein contained in home-grown forages by adding tannins. These are natural comp ounds, which, when bound with protein, make it unavailable in the rumen, instead releasing protein in the true stomach, where pH is lower. Previous studies had already demonstrated the potential of tannins for reducing the proportion of rumen degradable protein in forages. However, future research would examine its effect on high-yielding dairy cows, Prof Sinclair said.
