Cleantech expertise

Greater Cambridge has an exciting cluster of cleantech companies and environmental organisations.

Through our work with the St John’s Innovation Centre we have supported many of these companies in their early phases.

Below are extracts from some of the press releases we have produced for cleantech companies supported through a series of ‘Technology Press Days’ implemented by Holdsworth Associates on behalf of the St John’s Innovation Centre.


Imagine a refrigerator that used no harmful gases, ran silently and without vibrations, and used significantly less electricity than current models.

Such a machine is set to be reality thanks to pioneering research into magnetic refrigeration carried out by University of Cambridge spin-out Camfridge.

Wind Technologies

The world’s first commercial Brushless Doubly-Fed Generator (BDFG) was installed on a 20kW turbine on the University of Cambridge’s West site. 

This new technology will help the University meet its obligations under new legislation, which requires a new build to obtain ten percent of its electricity from renewable sources.


A nematicide based on garlic juice concentrate has been developed to provide a safer alternative to the chemicals such as aldicarb and methyl bromide which are extremely toxic and broad spectrum.

Dashboards, door panels and other internal car parts are usually made from injection-moulded plastics, but an Ely-based company is developing a green alternative that offers advantages in cost, performance, and resource use.

“We have already made prototypes for Nissan using a mixture of plant fibres held together by a synthetic matrix and we are achieving good results,” said Ben Schadla-Hall, marketing manager for Ecotechnilin.


An efficient and cost-effective alternative to sending waste plastic/aluminium laminates to landfill has been one of the ultimate quests of the recycling industry, and the problem has finally been cracked by Cambridge-based Enval.

Enval has set up a pilot plant which uses microwave induced pyrolysis to break down the laminate into its component parts which are then captured for re-use.

Tailor-made for laminated packaging wastes, the process has been designed to be energy efficient, demanding only modest capital and operating costs.

E-stack (now Breathing Buildings)

Cambridge researchers have found that in a well insulated building, body-heat, computers and lighting are sufficient to keep the temperature above 20°C and have developed E-stack, the natural ventilation system to refresh air without draughts.
