About us

We are Perpetual Next

Perpetual Next is an organization centred around three separate, but complementary business divisions (Trading, Conversions and Technologies) devoted to the valorisation of organic waste and residues into sustainable use to meet the growing demand for biobased energy, fuels, chemicals and materials. This is an opportunity to get returns from organic residues and to reduce waste and pollution. At the same time, it reduces the demand for and dependence on fossil fuels. The future is now. The future is Perpetual. 

Our vision

Population, industrial and consumer growth have placed enormous pressure on the availability of non-renewable, fossil resources. Whilst at the same time worldwide massive amounts of waste are dumped or disposed in some form of a landfill. Our planet is heating up and the climate is changing, with all its consequences. 
 
It is indisputable that as mankind we have to prevent climate change. The way we rely on our resources, the way we produce, consume and dispose, drastically has to change forever.
 
There is an infinite source of organic waste out there which can be converted into new high valued products and services. And these products and services eventually become part of that very same source of organic waste, again and again and again, forever.   

Our mission

Perpetual Next's mission is to reduce climate change by reducing, capturing and recycling carbon and to accelerate the valuation of organic residues into sustainable use and the transition from a fossil based to a renewables based stable circular economy. 

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