Ludgate Environmental Fund invests £14.1 million in resource efficiency

Ludgate Environmental Fund Limited ("LEF") is pleased to announce that it has agreed to make three new investments in biomass, anaerobic digestion and waste heat recovery, each with the expectation of significant growth potential.

Tamar Energy Limited ("Tamar")

As part of the UK's largest single commitment to anaerobic digestion to date, LEF announces that it is committing £7.0 million into equity in Tamar. The proceeds will be used to fund the development and construction of food and mixed waste anaerobic digestion plants that produce renewable energy. Tamar is developing a UK network of more than 40 plants with capacity to generate 100MW of electricity over the next five years. The company has an advanced pipeline of projects as well as experienced engineering and construction partners with proven success in the UK. Tamar announced in February that Sainsbury's, the UK's leading retail user of anaerobic digestion, is both an investor and strategic partner. Sainsbury's is working closely with its suppliers to help them access Tamar's plants and thereby reduce the environmental impact of their operations. LEF is investing alongside RIT Capital Partners plc, the Duchy of Cornwall, Fajr Capital and other investors to raise a total of £76.3 million.

Micropelt GmbH ("Micropelt")

LEF also announces today a £4.1 million (€5.0 million) growth capital investment in waste heat recovery company Micropelt GmbH, based in Freiburg and Halle, Germany. Mitsubishi UJF Capital Co. Ltd is participating alongside LEF and existing shareholders in a total fundraising of £5.3 million (€6.5 million). Micropelt's thermal energy harvesting technology uses waste heat to generate electricity, displacing batteries in automated equipment for a range of industrial and domestic applications. The company has strong partnerships with major semiconductor and system integrator players worldwide.

Ignis Biomass Limited ("Ignis")

The third investment, of £3.1 million in a combination of preferred equity and convertible loan notes bearing an 8 per cent coupon net of withholding tax, is being made for a majority stake in Ignis. The funds are intended for the construction of a biomass energy plant in Wick, Scotland to replace oil-fired heat production for the district heating network which is to be bought from the Highland Council.

Chairman of LEF, John Shakeshaft said, "We are pleased to make these three investments in high growth industrial cleantech companies. These deals represent diverse investment in critically important resource efficiency supporting sustainable economic growth."

Portfolio Subscription and Disposal

LEF has subscribed to £1.3 million of convertible loan notes into Terra Nova, alongside subscriptions by existing investors bringing the total invested to £3.6 million. These notes are a one year instrument bearing 6 per cent interest.

LEF also announces that it has redeemed 1,090,194 shares in New Earth Recycling & Renewables (Infrastructure) plc ("NERR") at 142.1 pence per share, receiving £1.55 million in cash. This compares to the subscription price paid by LEF of 135.9 pence per share. Following this redemption, LEF holds 2,180,389 shares in NERR which at a price of 142.1 pence per share values the remaining holding at £3.10 million.
