H2OPE for slurry treatment

The challenge of responsibly – and economically – reducing and treating organic slurries, manure and food waste is an ever-growing concern for many industries.

Our H2OPE technology is at the front line of tackling this challenge. Revolutionising how businesses recycle their waste, whilst simultaneously and significantly reducing their carbon footprint.

The on-site, zero-waste, energy efficient slurry treatment technology transforms what was once a burdensome ‘waste’ product into valuable, high-quality by-products.

Generating saleable by-products is H2OPE’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 water which is able to be discharged safely to the environment or re-used.

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


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


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

    The H2OPE process produces competitively priced natural pelletised 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.

    The natural based fertiliser offers a sustainable alternative to peat-based products which will be banned from use in 2024. Our laboratory team have analysed and compared the nutrient values of each product to confirm that our natural alternative contains the required nutrients for healthy crop growth without the large carbon footprint.

  • 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

    Water is essential for agriculture, from growing fresh produce to sustaining livestock – its role is crucial, but its value is often forgotten. Our H2OPE process play a key role in alleviating stress on freshwater resources. Water is separated from dry matter to be cleaned and polished, this can then be reused for irrigation of agricultural land, drinking water for livestock or safely discharged to the environment.

Applicable SDGs

How does the slurry treatment technology work?

  • Volatile contaminants are removed from slurry through thermal desorption.
  • H2OPE dewaters slurry 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.
