The Horticultural Halls and Conference Centre (RHH) is to host 2011's Energy from Biomass and Waste and Adventure Travel Live exhibitions, it has been announced.
Maugie Lyons, head of commercial operations at the RHH, said: "We have always prided ourselves on being one of the best venues in London for launching niche exhibitions and are delighted that these shows are returning for another year.
"Both events had excellent feedback from exhibitors and visitors alike and we are confident that they will repeat their success next year."
