Introducing Soil Enhancement

Conventional composting relies on the natural decay or rotting processes of organic matter. Depending on the composting process employed, it can take weeks for complete organic matter decomposition.

Composts often produce an inhomogeneous mix in varying stages of decay. As a result, compost that is not properly broken down will not be stable and is prone to further decomposition, mold, and odor after application.

This is especially problematic when the compost is re-wetted. In contrast, Harp Accelerated Bio Digesters utilize mechanical process and proprietary microorganism/enzyme mix to ensure rapid and complete, total breakdown of food waste to fertilizer in just 24 hours.

Fertilizer soil stability

Fertilizer soil stability refers to the beneficial enhancement of soils, including:

  • Improved physical structure (soil integrity, density, porosity etc.)
  • Increased organic carbon content (ability to store and return carbon to soil)
  • Increased water stability (water absorption & retention, erosion resistance etc.)
  • Improved bioavailability of macro-nutrients and micro-nutrients and thus nutrient uptake by plants Harp’s premium organic fertilizers perform extremely well in all these key aspects.

To enhance performance and plant health when using organic fertilizers produced by Harp BioDigesters directly “on-site” Harp recommends aging the material for 10-14 days prior to application to ensure the release of an optimum balance of nutrients for plant growth and health.

The fertilizer can be simply stored on-site in open containers during this time. Whether the fertilizer is applied immediately or allowed to mature prior to application, once the nutrients are released into the soil, the plants, gardens, or fields will experience long-lasting nutritional benefits. Harp can provide recommendations for fertilizer application rates for bulk applications as well as potting mix use

Fertilizers

Fertilizer is a material that is applied to soil to supply one or more nutrients required for plant growth. Fertilizer can be produced from natural materials (organic fertilizer) or industrially manufactured (synthetic fertilizer).

Organic Fertilizer are derived from vegetable matter, crop residues, food waste, animal excreta (manure/slurry), human excreta, and guano. Harp’s BioDigester technology produces premium organic fertilizers that increase soil health and fertility.

Synthetic Fertilizer ~50% of the world’s food production currently relies on synthetic nitrogen fertilizer – an 800% increase between 1961 and 2019. As described below, synthetic nitrogen production requires huge amounts of energy, generally in the form of fossil fuels. Over 140 million tons of ammonia are produced each year to make synthetic nitrogen fertilizer for crops. Industrial ammonia production emits more CO2 than any other chemical making reaction. These Greenhouse Gas (GHG) emissions are a key driver of global warming.

''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.”
