‘Zeff’ is the force that pulls electrons towards the nucleus — the measure of positive charge. By closing the loop between use and waste, we aim to be a force of positive change in the world. We’re working tirelessly to make our product – and your recycling process – as economical and low-impact as it can be.

How can we ask other businesses to change their behaviour if we haven’t changed our own? 85% of our electrical energy comes from the Avonmouth wind and solar park. And we work from an award-winning eco office park called Filwood Green, which has a number of environmentally-positive features. Photovoltaic panels spanning most of the roof provide home grown green power, while electric vehicle charging, secure cycle storage and showers make sustainable commuting a breeze. The ecology is buzzing too, thanks to the sedum green roof and wildlife ecology areas. It’s no wonder it is certified BREEAM outstanding.
