A great H2OPE on the horizon

We understand the challenges involved in processing digestate – handling, storage, transportation and land application. We also know what the picture looks like if we don’t take action to resolve these challenges.

Our H2OPE AD technology is designed to minimise the impact of handling digestate on the environment, whilst optimising the valuable nutrients into saleable by-products.

The on-site, zero-waste, energy efficient digestate treatment technology delivers a viable, sustainable option when it comes to digestate treatment.

Generating saleable by-products is H2OPE AD’s most significant commercial advantage. It also delivers on waste reduction, optimised waste management and disposal and pollution control – adding value as part and parcel of the process.

What’s more, water is also treated and polished to provide clean water which is able to be discharged safely to the environment or re-used.

Each H2OPE AD system processes a minimum of 12,500 tonnes of digestate per year, contributing to a minimum saving of 656 tonnes CO2e.

What’s in it for you and the planet?

  • Eliminate up to 73% of emissions from digestate management
  • Drastically reduce ‘waste’ volumes
  • Reduction in transportation requirements
  • Minimised over-nutrification of land
  • Protect waterways from diffuse pollution
  • Elimination of bio-security concerns
  • Clean water for re-use or safe environmental discharge
  • By-product commercial yield increase

Sustainable by-product production

  • Natural Fertiliser
    Natural fertiliser is produced with 97% less emissions compared to inorganic products.

    The H2OPE AD process produces competitively priced liquid natural fertiliser which can be easily applied on farmland with already available machinery. This mitigates many of the issues surrounding the spreading of slurry on agricultural land, including over nutrification of land and potential pollution of waterways. Almost all water is removed, enabling economical transportation to the rest of the UK, Europe or indeed globally.

  • Growth Media
    Our all-in-one growth media is peat and coir free – saving up to 630,000 tonnes of carbon annually.

    By utilising dry matter, the H2OPE AD system produces a recycled, premium slow-release fertiliser or all-in-one growth media at a fraction of commodity prices. The fully customisable growth media can be used in growing houses and vertical farming environments, providing a fully circular process.

  • Biodegradable Plant Pots
    Just 31% of all plastic pots, tubs and trays are collected for recycling.

    The dry matter from slurry treatment can also be repurposed into 100% biodegradable plant pots for use on a commercial and wholesale level, eliminating the use of plastic. The 100% peat and coir-free pots provide a sustainable alternative to plastic pots which are traditionally manufactured from HDPE which has a carbon footprint of 6kg CO2 per kilogram of plastic!

  • Reusable Water
    Digestate contains 92% water.

    Our H2OPE AD process effectively separates the water fraction from digestate. The system cleans and polishes the water so that it can be safely discharged to the environment or reused in the AD process.

Applicable SDGs

How does the digestate treatment technology work?

  • Volatile contaminants are removed from digestate through thermal desorption.
  • H2OPE AD dewaters digestate and optimises the valuable ingrained nutrients.
  • The captured nutrients are transformed into saleable by-products.
  • Water is also cleaned for safe environmental discharge and/or re-use.
