Zouk Capital has announced three cleantech investments totalling more than €40m (£34m) from its latest fund, Cleantech Europe II.
The fund closed earlier this year at €230m and offers growth capital investment in cleantech companies.
The first company, FFK Environment, uses proprietary technology to produce refuse-derived fuel (RDF) from multiple waste sources.
The second business, OZZ Electric, is a full-service energy efficiency and electrical contractor in Canada. In partnership with OZZ Solar, the company offers commercial customers installation services for energy efficiency and solar technologies.
Finally, Zouk has invested in va-Q-tec, which works in advanced thermal insulation. Based in Germany, va-Q-tec designs and produces vacuum insulation panels used in refrigeration, packaging, cold-chain logistics, construction and automotive applications.
