Summerleaze has blown through a number of businesses -- aggregates, waste disposal, and renewable energy. The family-owned company, originally in the gravels/aggregates business, branched into using methane gas from the waste disposal landfills to make fuel. After acquiring renewable energy firm Thomas Graveson, it created Summerleaze RE-Generation, which has enough capacity (43 MW) to serve 70,000 houses from sites across the UK. Ennate Technology provides power generation equipment sales, maintenance, and hire services; its Green Hydrogen subsidiary supplies renewable hydrogen and oxygen for clients. Summerleaze also has a biogas unit, Summerleaze AnDigestion.
