A Dumfries & Galloway waste project is among the assets of a £160 million investment company that is being listed on the stock market by infrastructure investor John Laing, to capitalise on demand for energy assets.

The fund, called John Laing Environmental Assets Group, is seeking to raise between £160m and £174m to invest in a range of projects, notably renewable energy and waste and waste water private finance initiative schemes, in the UK.

Chris Tanner, lead investment adviser at John Laing Capital Management which will oversee the fund, said: "An increasing focus on sustainability and making use of natural and waste resources, coupled with strong legislative support to encourage private investments in environmental infrastructure projects, form a favourable backdrop to the launch of this diversified and well-balanced fund."

The initial portfolio will be a group of environmental infrastructure assets to be purchased from John Laing and a fund run by fund manager Henderson.

Among the businesses is D&G Waste, a private finance initiative project that John Laing bought from Shanks Waste Management in 2010. Under the scheme much of the waste is directed to a mechanical biological treatment facility.

As well as another waste processing project, the fund will have two solar projects, three onshore wind farms and two wastewater treatment schemes.

The fund is aiming to deliver a yield of around 6% and much of its revenue is inflation-linked..

John Laing has said that it would buy up to 24.9% of the shares on offer.

Henderson bought John Laing in 2006 for £887m. In September it appointed investment bank Greenhill to advise on a possible sale or listing of the infrastructure group.
