GREEN entrepreneur Trelawney Dampney is planning a £50 million expansion to the green business he started from a tiny plot of land.

The Parley businessman has three major new plans, including one of the biggest solar farms in the country, for Eco Sustainable Solutions near Bournemouth Airport .

He started the firm 19 years ago and it recycles green waste, soil and food on behalf of Bournemouth, Dorset and Poole Councils.

He now wants planning permission for hundreds of six foot high solar panels on a company-owned grazing field about 90 acres in size. The scheme would be worth more than £25m alone.

“It will be right up there with the biggest solar farms in the country,” said Mr Dampney, speaking at a public open day on Saturday.

“The panels will not be visible from public land. Sheep will still be able to graze underneath them.”

He already has planning permission for a £7m biomass plant to burn waste wood like MDF that cannot be recycled. At present it is shipped to Sweden and burned there. The new plant would produce 23,600 megawatts of electricity per year and is expected to open in mid-2014, thanks to funding from a venture capitalist.

Trelawney said: “There will not be any smoke at all. The most you will see is a little steam.”

The excess waste from the burner would also be used to warm up enclosed tanks of waste food in a proposed £14m anaerobic digester facility.

The food is broken down naturally into gas and Eco estimates it will generate enough methane to supply 3,000 homes a year.

Mr Dampney said there would be no smell from the enclosed tanks.

The company is now seeking planning permission for the solar farm and the anaerobic digester.

Mr Dampney said: “We are moving into energy regeneration but we will carry on doing all the good recycling work that we do. Recycling is still the best way of dealing with waste.”
