Our Technologies




Biodegradable waste to energy

Wood pellets, wood chips and other biomass offer a completely sustainable alternative to other fuel sources. Renen use innovative and best in class technology to convert waste biomass into energy as either heat or electricity. Fantastic for spacial heating of large areas like seed nurseries or large water volumes like swimmign pools or hot water solutions for the hospitality or farming industries.



Harnessing the power of nature

Biogas is currently a largely untapped source of Renewable Energy. It is a by-product of waste. Waste that we all contribute to on a daily basis. It has a High Energy Density (ED) in comparison to other Renewable Energy Sources and this, combined with the organic fertiliser by-product, will make this technology increasingly popular in the near future as fossil fuels dwindle and prices sky rocket.



World class high technology

Renen carefully and continually researches a diverse range of products in this ever changing and highly competitive market. We carefully select what we believe are highly efficient, durable and affordable products that not only compliment our unique approach to our composite technology platform, our solar thermal solutions or our off-grid soultions but will exceed your expectations.
