About us

We are Perpetual Next

A climate technology company. With our 135 employees and six own production facilities, we work daily on and with solutions to combat climate change.
Perpetual Next is organised into three business units (BUs), each with their own specialisms, dedicated teams and their own strategic partners and customers.

Bio-conversions - Our Bio-conversions business unit focuses on the development and acquisition of companies where low-quality organic residual materials are converted into sustainable products and/or semi-finished products, such as heat, electricity, biogas, liquid CO2 green gas and fertilizers. We work with a wide variety of residual materials, including pruning and garden waste, but also waste from the food processing industry. We use various existing technologies that we have optimized for this.

Biocarbon – Our Biocarbon business unit produces renewable carbon from bio-residues such as forestry residues, scrap wood, etc. A technology that we have perfected in our unique carbon converter technology: C-Vertr. This is a process of thermochemical conversion of organic waste in an oxygen-poor environment.

Developments - our Developments business unit mainly focuses on gasification of renewable carbon and/or local agri-residual flows . Syngas is created from gasification which can form the basis for products for the chemical industry. By means of downstream technology, the syngas can also be converted into products for shipping and utilities, such as methanol, hydrogen and green gas.

Our vision

A growing world population, industrial growth and consumerism have put enormous pressure on the availability of fossil resources. At the same time, huge amounts of waste are being produced, dumped or disposed worldwide. Our planet is heating up and the climate is changing, with all the consequences that entails.

We are a climate technology company that retrieves carbon and gas from organic waste. With our technologies, we help industries around the world become fossil-free and circular.

This is how we are transforming our industry from the biggest climate problem to the biggest climate solution.

Our mission

Perpetual Next is committed to removing 1 gigaton of CO₂ from the atmosphere by 2050. The focus of the technology and application is on fossil gas & carbon avoidance and carbon removal: extracting CO₂ from the atmosphere and storing carbon in products that would otherwise end up in the atmosphere. This is how we help in our mutual journey toward a CO₂-neutral 2050.

If we take care of nature, nature will take care of us.
