Our story

Green Technologies for a Sustainable Future

The company was established in 2009, Changeover Technologies (formerly known as Silform Technologies) began to develop a formula and process that would revolutionise the re-use of fine particle waste.

The company had developed an environmentally clean, high-volume, low-cost pelletising systems (FuelForm® and MetaForm®) for the conversion of waste deposits into pellets that had great economic value.

Fast forward and Changeover Technologies Ltd has secured over £5m in investment led by the Bank of Ireland’s Kernel Capital Growth Fund, in a syndication with private investors and supported by the Co-Investment Fund Northern Ireland. We upscaled our research and development team, filed three new patents, and successfully completed a 5T per hour pilot test plant in Northern Ireland. Our new laboratory premises are situated at the renovated Old Gasworks in Belfast. 

Our patented technology embraces many of the United Nations Sustainable Development Goals for the mining industry, and in 2021 we were recognised as Silver Level Innovators in the Innovate NI Innovation Accreditation programme.

Silver Innovator Award

In 2022, we will launch SilForm® high grade silicone reductant pellets for the silicon market, suitable for high temperature EAF processes.

We continue to cooperate with industry in the development of our ground-breaking net zero biocarbon pellets. BioForm®.

This complies with our transitionary strategy into scarce high-end carbons and biocarbon alternatives.

Our R&D pipeline is ongoing and continues to make successful advances with various environmental remediation solutions, with our AgriForm® product leading the way in a solution for legacy utility ashes and agricultural wastes. 

As a company we are 100% committed to helping producers on their journey to net zero, we are drawing on our wealth of pelletising knowledge, amassed through the years of extensive R&D.


Our goal is to produce greener solutions for the handling of environmentally damaging wastes, harnessing the true value of waste ensuring a true circular economy.
