Harp waterless food waste recyclers use proprietary biotechnology in the form of thermophilic microbes, mechanical rotation, heat, and airflow to break down food waste and convert it into a valuable soil amendment fertilizer in 24 hours.

The end product is not compost. It is a nutrient-rich, stable soil amendment that acts like a slow-release biofertilizer.

No. Using aerobic microbial processes, Harp machines reduce odors commonly associated with food waste decomposing.

The end product produced by the Harp Renewables food waste recyclers can be used for landscaping, given away, or packaged and sold. We recommend blending it with compost or soil at an 8:1 ratio.

Yes, Viably will train your team on the usage and maintenance of the Harp food waste recyclers when the machine is installed at your location.

Food waste, including small fish and chicken bones, can be put directly in the Harp Renewables food waste recycler. Large meat bones, shellfish, and compostable food items need to be shredded before being put in. Manure and bedding can also be processed through the Harp units. 

Harp Renewables waterless food waste recyclers can be installed both indoors and outdoors, depending on the available space and requirements.

Yes, we recommend covering the Harp Renewables food waste recyclers if located outdoors.

No, Harp units do not require any water supply.

Yes, information regarding the carbon footprint of Harp Renewables waterless food waste recyclers can be provided, showing the environmental benefits of each system.

We work with any business that produces food waste, including corporate campuses, hospitals, restaurants, grocery stores, schools, and others. We also work with waste haulers, composters, and waste processing facilities.

Similar end-product nutrient profiles can be expected for similar input material (e.g., cafeteria food waste vs. manure).

Yes, Harp waterless food waste recyclers can process compostable packaging materials when put through a built-in shredder, reducing waste and promoting sustainability.

Plastic won’t cause any damage to the machine, but it’s preferable that it doesn’t make its way into the waste stream to begin with, as it is a contaminate.

The moisture from the food waste recycling machine is vented as steam vapor. Some condensate, which is just H2O, comes off the vent and can be put down a drain.

Viably offers bin lifters, built-in shredders, and automated feed hoppers as optional accessories for the Harp Renewables food waste recyclers. For larger systems, we can string together multiple units with stacking augers.

No. If the Harp Renewables food waste recycler hasn’t been fed, it will enter a dormant state after 48 hours of non-use. The microbes will also go dormant until fresh food is added – up to 6 months.

There is a wide range of machines to suit operations of different sizes. Harp recyclers range from 38 gallons (224 lbs) to 1,887 gallons (5.5 tons) per day. In addition, multiple machines can be connected together to increase overall processing capacity.

Based on the size of the machine, the range of energy consumption is 7.68 kWh/day to 244.13 kWh/day.

No, unlike batch digesters, the Harp Renewables waterless food waste recycler can be continuously fed. We recommend feeding the machine 3-4 times a day.

Daily maintenance is short and easy – we estimate 10 minutes. The air filter needs to be cleaned daily and a visual inspection conducted.

Annual maintenance includes replacing the carbon pellets every six months, greasing bearings, and replacing the nylon pads on the auger paddles if they are worn (approximately two years).

Harp recyclers almost never need to be cleaned. If standard operating conditions are met, there is no need to clean the interior of the machine as that would disrupt the biological processes.

Yes. Harp Renewables food waste recycling machines can be connected via an ethernet cable. Temperatures and alerts are monitored. Weights are also tracked on each machine which can be used in sustainability reports.

All Harp waterless food waste recyclers  are manufactured in Brownstown, Kentstown, Navan, Co. Meath, Ireland.
