Impax announces new additions to its Venture Capital Portfolio

Impax Asset Management Ltd, the wholly-owned subsidiary of Impax Group plc, has revealed details of its growing portfolio of venture capital (VC) investments.

Following the highly profitable disposal last year of its investment in Cellex Power Products Inc, a Canadian fuel cell company bought by Plug Power Inc (NASDAQ: PLUG), Impax now holds investments in seven companies covering a broad range of environmental activities.

The portfolio includes three recent additions, New Earth Solutions, Nordic Windpower and Emergya Wind Technologies (EWT). Whilst New Earth is helping to tackle the growing challenge of diverting waste from landfill, Nordic and EWT are bringing established wind turbine designs into the commercial market. Impax has invested nearly £12m across these three companies.

Previous smaller investments have been made in Ensyn, a Canadian biomass pyrolysis technology; Pelamis Wave Power, the Edinburgh-based wave energy developer; Sterecycle, a UK autoclave waste treatment developer; and RecovCo, which developed a technology for improving aluminium recycling yields and then purchased Affimet, the largest French aluminium recycling business, from Alcan.

Nigel Taunt, Impax's Director of VC Investments, said: "Impax invests in later stage venture capital, fitting comfortably alongside our portfolios of environmental companies operating in public markets. They need to be candidates for flotation, a qualitative judgement that means we believe they could IPO within 2 years. We are now looking to commit at least £3m into each new investment, leaving headroom for follow-on support when required."

Impax is one of the UK's largest quoted environmental investment managers with over £1bn of funds under management or advisory mandates. The two flagship funds, Impax Environmental Markets plc and Impax Environmental Markets (Ireland), have around £600m invested largely in quoted environmental stocks worldwide, with 10% (c.£60m) available for later stage venture capital. If private company investments achieve a listing in due course, they move seamlessly into the quoted portfolio.

Companies welcome Impax's involvement as an investor because of its long standing expertise in the field. Speaking after Impax's recent investment in US wind turbine manufacturer Nordic Windpower, Steve Taber, Nordic Windpower CEO, said: "The managers of Impax are among the most knowledgeable and experienced investors in the entire cleantech space. We look forward to their guidance and judgement, as Nordic grows in the global wind industry."

Impax has invested alongside Goldman Sachs in both Nordic Windpower and Sterecycle, alongside Emerald and Rabo Ventures in EWT and with Wheb Ventures and Stonefund in RecovCo. Pelamis has a long list of well known investors on its share register.

"We see other venture capital investors as potential partners, not as competitors" said Jonathan Fogg, Investment Manager, VC Investments. "We hope that others will welcome us as co-investors because Impax can help build an investor book and groom companies for public markets. We're long-term investors, so an IPO can be a staging post along the way, not an automatic end game".

"We have a strong pipeline of potential investments and are always keen to meet both new companies in the environmental sector and potential co-investors. This is a fast growing area and the opportunities to create value are looking excellent," he added.

Nordic Windpower: £4.0m, February 2008

With offices in California, Sweden and London, Nordic Windpower manufactures and sells competitively priced and highly reliable utility-scale, two-bladed wind turbines to large and small developers and community wind projects worldwide.

Emergya Wind Technologies: E5.0m, January 2008

Emergya Wind Technologies Holdings N.V. is a Dutch- based manufacturer and supplier of wind turbines and turnkey wind parks.

New Earth Solutions: £4.0m, December 2007

New Earth's technology is fully enclosed with a sophisticated air handling and treatment system. The technology prevents the output of the odour emissions or bio-aerosols normally associated with traditional biological treatment processes.

New Earth's processes were researched and developed over a period of 7 years and according to the Environment Agency's formal assessment are proven to divert over 80% of biodegradable municipal waste from landfill, whilst recovering dry recyclables. The technology is housed in low impact buildings and waste treatment is delivered through processes which are acceptable to local communities.

In 2007 New Earth secured a £50 million finance package from the full service commercial bank Norddeutsche Landesbank.

New Earth's technology services both municipal and commercial clients. New Earth is working with Asda to deliver the store's first zero waste to landfill supermarket in the UK.

Recovco: £1.5m, April 2007

RecovCo Ltd. is a UK-based specialist designer and operator of aluminium reprocessing facilities. Its unique and patented Rotary Tilting Furnace (RTF) technology has been successfully installed in two sites in the UK where it has demonstrated unprecedented operational performance and metal recoveries. Furthermore, the RTF technology offers best in class environmental performance.

Founded in 2004, it is RecovCo's vision to become the best reprocessor of aluminium dross and scrap in the world - in terms of operational excellence, environmental performance, customer service and profitability.

Sterecycle: £3.25m, November 2006 and January 2008

Sterecycle recycles waste that would typically be landfilled. Its proprietary autoclave technology treats unsorted domestic and commercial wastes and converts the organic portion into a renewable energy biomass. Non-organic waste - like glass, plastics and cans - is separated out and sent for recycling. The company has raised over £20m of equity finance to date and is planning to IPO within the next two years.

The first Sterecycle plant is under construction in Rotherham and will be opening for business in mid- 2008.

Ensyn Technologies Inc.: £1.0m, July 2006

Ensyn Technologies, based in Ottawa, Canada, has developed an industrial integrated biomass refinery which uses Rapid Thermal Processing (RTP) to produce biofuel and other valuable chemical products from what would otherwise be a waste source such as sawmill waste. Pyrolysis is the conversion of biomass into a liquid, from which chemicals and energy can be extracted. This energy can be converted into liquid fuel for heating, and eventually for transportation.

Pelamis Wave Power: £1.3m, April 2006 and June 2007

Pelamis Wave Power Ltd, formerly called Ocean Power Delivery Ltd, has developed a unique system to generate renewable electricity from ocean waves. The Pelamis Wave Energy Converter is the world's first commercial scale machine to generate electricity into the grid from offshore wave energy and the first to be used in commercial wave farm projects.
