About Us

Sustaining people, planet and business in equal measure

SEM was born of a tenacious drive to do more with less. To recover precious nutrients and resources from ‘waste’ products so that businesses – and the environment they inhabit – can flourish.

We strive to protect our planet’s ecosystem by processing and re-using waste co-products, and by reducing emissions from transporting these co-products on our roads.

There is a better solution. This is it.

Who we are

We collaborate with businesses across the agriculture, biogas, aquaculture and distillery markets to address their waste management challenges. Our team works in partnership with yours to implement our tailored solutions at every stage of that challenge.

We create, develop and apply market-disrupting environmental technologies which aim to positively impact businesses by:

  • Reducing the effects of waste on the environment
  • Supporting the evolution to net zero
  • Optimising supply chains and increasing resource efficiency

We are working around the globe to build climate resilience, which goes hand-in-hand with generating jobs and prosperity for all. Our solutions are completely scalable and applicable across both market sectors and borders.

  • We’re partners.

Our Mission

To minimise the impact of waste on the environment and - where possible - create value from its co-products, with sustainability in mind.

Our Vision

Our vision is a waste-free, circular economy in the future, securing our planet’s health and wealth for generations to come.

Our Values

We value the planet we live on. That’s why we pioneer coming-of-age technology that fosters a circular economy.

UN Sustainable Development Goals

The UN’s SDGs are 17 ambitious goals which are an urgent call for action by all countries in a global partnership.

Actions to tackle the biggest challenges of our time, accelerating strategies to achieve tangible social, environmental and economic change.

At SEM we recognise that everything we do contributes to these goals: pioneering technological solutions to tackle climate change and working with our partners to conserve and re-use resources. These go hand-in-hand with reducing inequality, improving health and boosting economic growth.

“The reason we feel so passionately about creating and supporting an accountable economy is because we understand what the picture looks like if we don’t.”
