About Us

CSS Renewables is a UK company specialising in the delivery of technology-led solutions across energy generation sectors. We specialise in the Waste to Energy, Bio-Mass and Solar sectors. We have developed a robust, proven and warranted supply chain for a profitable application to a huge waste market that has a significant thermal processing capacity after recycling.

The localised approach to thermal treatment post recycling & recovery significantly reduces national carbon footprint and will divert waste from landfill and remove the need to export millions of tonnes of waste every year.

Work with us


We provide very clear, concise details to our clients. The route to a successful project is complex and demanding, we work with our clients at every step of the process.


We deliver a lot of very detailed process information, under pinned by a thorough understanding of what the client needs – but only after we have taken the time to understand their business and the specific project requirements.


The driving force behind any successful project will be industry leading equipment. We only supply technology that is tried, tested, and have proven references. Our partners have delivered their equipment across the globe and have supplied globally recognised brands.

R&R Beth

R&R Beth

R&R Beth was founded in 1887 by W.F.L. Beth, an engineer from Lubeck who invented the world’s first bag filter. The patent was issued as number #38396 by the ‘’Kaiserliche Patentamt’’ on January 26, 1886. Soon, the BETH® bag filter found its way into other industrial branches besides grinding mills, and during the 20th century, the BETH® machine factory grew into an international leader in the field of industrial dedusting. At first, filtration was predominantly used for improving production processes, but over time it also became an important factor in operational safety and pollution control – long before ‘’environmentalism’’ was an international buzzword. Reducing noxious and hazardous dust emissions made industrial production not only more economically efficient and environmentally friendly, but also more humane. It was not long before the term ‘’BETH® Filter’’ became a synonym for dedusting itself. In 1956, wet and dry electrostatic precipitators were added to the company’s range of products.
