Introducing Harp Bio Digesters

Harp Bio-digesters is a range of aerobic food waste digesters which are capable of digesting 1,000 up to 50,000 litres/5.5 tons of food waste a week, reducing it’s volume by an average of 70%. In a short 24-hour period, the bio-digesters produce a nutrient rich, premium output that can be used as a soil enhancer, biomass fuel or anaerobic digestion feedstock. With huge economical benefits along with a vast array of environmental benefits, the Harp bio-digesters will save you costs, while you save the planet!

The Harp bio-digester process retains the increasingly important nutrients that would otherwise be lost to the breakdown and decay of food waste in bins or at landfills, as methane and Carbon Dioxide are released into the air. Instead, the valuable end product is then used to replenish soils that have been excessively harvested, replacing the carbon, ammonia and phosphorus that helps inspire strong growth.

There are six different Harp bio-digester models available in the range. The Harp experts will complete an onsite survey and then design and size the correct digester to match your requirements. Harp also offers a full Aftersales service experience in which the Harp specialists look after all maintenance required. Contact Harp today using our free consultation contact form below.

Benefits to the planet

 

  • Reducing the carbon footprint– our bio-digesters do not release carbon into the atmosphere as no methane is produced during the digestion process. Carbon is stored in the digestate which is then returned to the ground through our product, where it belongs!
  • Say goodbye to landfill- Keeping organic materials out of bins and away from landfills is hugely beneficial for the environment.
  • Waste reduction- waste can be recycled almost immediately on your site.
  • Cleaner emissions- remove the unnecessary transportation of waste collector vehicles.
  • Zero water demand – No wastewater discharge or disposal occurs with our bio-digesters unlike other digesters on the market.

The Process

 

  • Organic waste is added to the Harp Bio-Digesters system.
  • Material is heated to a constantly monitored core temperature of 72.C
  • Enzymes begin to break down the material as the paddles move the material across the digester.
  • After 24 hours the Harp Bio-digesters process is complete and the nutrient rich, safe end-product is augured out.

How it works?

Harp Bio-digesters need to be fed just like you and me, gradually and in stages. Steadily feed your Harp Bio-digester your food waste. A morning, mid-day and evening feed is optimal. Too much at once isn’t good for digestion.

The Bio-digesters process provides optimum conditions for microbes to break down organic materials, including cellulose into a nutrient-rich bio-fertilizer/biomass fuel.

''Delighted''

“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.”
