Kilmac Group has acquired a biomass business for an undisclosed sum to boost its renewables division.

All seven staff at Angus-based Eco Biomass and its founder George Penman will transfer over as part of the deal.

Kilmac, which has its headquarters in Perth, already has onshore wind and hydro in its energy arm.

Richard Kilcullen, co-founder and director of Kilmac, said: "I'm confident that with the orders Eco Biomass has in the pipeline, and the growing interest in biomass as a heat and energy source, we can triple the workforce and take turnover to around £5 million within the next two years."

Mr Penman, 28, said he was delighted with the deal.
