“We haven’t sent any waste offsite since we installed the bio-digester in December, The bio-digester makes people think a bit more about what they are doing and keeps everyone focused on ‘green’ ways to process waste. The process has been embraced by our tenants and has got them thinking more about waste segregation. They now unpackage their sent produce. As a result, not only are there no contaminated bins coming through, but we are creating added revenue by bailing our plastic. In preparation for a return to normal operations, we look forward to installing a second Harp – bio digester. We are delighted with this initiative which directly feeds into our People Planet Sustainable Strategy” – Michael Farrell, Estate Manager at Captial Dock Aramark Properties.

''Ideal Solution''

“Our customers are delighted that they now have a solution for food waste and are not contributing to unnecessary environmental damage caused by sending the organic matter to landfill. Harp Renewables has been hugely helpful and very responsive to any questions we have had, particularly in the early days while everyone was getting used to using the bio-digester. There has also been a lot of interest in the bio-digester from other Local Authorities and the DCCAE. It would be an ideal solution to any organisation with excess food waste and I would have no hesitation in recommending Harp Renewables to any interested party.”  – Bernadine Carry, Environmental Awareness Officer at Meath County Council shares

''Great Educational Tool''

“We invested in a Harp CX5 Bio-Digester with a bespoke integrated biomass boiler as a solution to our waste costs. We are saving around £11,000 annually now. With this solution we are also able to use the biomass boiler to heat out facilities which in turn dramatically reduces our heating’s C02 emissioons. All the excess digestate is then used as an organic fertilizer in our on-site greenhouses. This is a great educational tool to teach all the students about sustainability so thatin the future, students are interested and determined to make this world a greener more environmentally friendly place to live.” – Penair School
