Intelligent and easy solution to your waste problem

We have spent over a decade aggregating and integrating the best technologies to solve the waste problem. 

We have developed a viable commercial opportunity based on recovering resources for the circular economy.

This is all achieved using our unique water-based solution, requiring no chemicals, and without using incineration or ‘waste to energy’.

200,000 households

A HYDRACYCLE™ plant can handle the waste of up to 200,000 households: accepting 120,000 – 250,000 tonnes of waste per year, delivered using existing local waste collection infrastructure.

Our plants accept many types of mixed wastes including: municipal solid waste (MSW), sorting plant rejects (MRF-rejects), refuse derived fuel (RDF), and many commercial and industrial wastes (C&I).

The HYDRACYCLE™ revolution

How is the business model for HYDRACYCLE™ comparable with that of smart phones, like the iPhone? 

They are both platform technologies.

Smart phones contain key pieces of hardware which enable apps to be integrated with the core platform to generate a myriad of useful outputs.

Similarly, Fiberight’s HYDRACYCLE™ technology is a platform, containing ‘hardware’, which recovers resources. The HYDRACYCLE ™ bolt-ons (like apps) can be integrated with this core platform to upgrade the resources into high-value materials and products.

Like the best smart phones, HYDRACYCLE ™ is a world leading technology creating opportunities for growth in multiple market sectors. 

Innovative water-based recycling

HYDRACYCLE™ uses water as a separation medium to clean and segregate materials. Food waste and organics are ‘washed off’ the raw resources in mixed waste so that clean, contaminant free materials are obtained for recycling.

The dirty water, containing food waste, is treated via anaerobic digestion to produce a renewable energy by-product (biogas). Clean water is recovered after treatment and re-circulated back to the plant.

Each plant is operated with a closed water-loop ensuring minimal discharge to sewers and waterways, protecting the environment from leachates and microplastics.

Our unique anaerobic digestion solution uses high-rate liquid-feed reactors, producing little to no digestate. Our solution works effectively for unsorted mixed waste of varying composition, including waste with high proportions of food waste and organics. The biogas output from a large MSW plant can generate over 5 MW of green energy.

All on one site – The process

Step 1

Waste in

The waste is delivered to our facility using the current and local waste collection infrastructure.

Step 2

Size separation

The waste is de‐bagged, placed onto a conveyor and then separated into two size fractions using a trommel.

Step 3

Recovery: textiles and small WEEE

Textiles are recovered from the larger size fraction prior to pulping.

Bulkier items such as toasters and kettles (small WEEE) are separated from the rest of the waste stream.

Step 4


Both size fractions are pulped to break down the size of the organics (paper/card and food).

This allows them to be separated from larger recyclable plastics (rigid and flexible) and metals.

Step 5

Washing & extraction

The pulped material is washed with water to separate food waste from other materials.

Clean fibre is then extracted away from a ‘reject stream’ containing small plastics and inerts.

Step 6

Anaerobic digestion

Food waste solubilised in the water is processed through fast anaerobic digestion; producing biogas (renewable energy) and clean water which is recycled back into the process.

Bolt-ons are technologies that can be integrated with HYDRACYCLE™ to upgrade recovered resources into market-ready high-value materials and products.

Fiberight is designing bolt-ons both internally, and externally with technology collaborators.

Multiple bolt-ons are in development for each raw material stream so that the process can be flexible and adapt to the market conditions of where each HYDRACYCLE™ plant is located.

Bolt-on integration enables optimisation of logistics, heat, energy and water.

All on one site: Just like people were amazed that so much could fit into the palm of your hand with a smartphone, HYDRACYCLE™ changes the perception of what can be achieved on one site.

A myriad of bolt-on options exist. A wide array of technologies can be integrated with HYDRACYCLE™ including hydrolysis, pyrolysis, gasification and fermentation.

Examples for fibre and plastics bolt-ons are given below.

Bolt-on example 1: Fibre products & platform sugars

  • Bolt-on technologies have been developed to convert the loose fibre into a format suitable for use in biomass fuel, agricultural products and pulp-moulding applications.
  • Bolt-on technology has been developed to convert the fibre, which has a high cellulose content, into platform sugars (e.g glucose) for use in industrial biotechnology to produce green chemicals, plastics, and fuels.  A lignin-rich residual solid remains after sugar conversion. This can be used in the manufacture of solid fuels, adhesives, grouts.

Bolt-on example 2: Plastics

  • Bolt-on technology has been developed for the separation of rigid plastic packaging (bottles, pots, tubs etc) and flexible plastic packaging (carrier bags, food wrappers) into purified mono-material streams.
  • The core process separates out rigid and flexible plastics. These two streams are then shredded and passed through various clean-up steps to separate out the different plastic materials. The plastics in residual waste are primarily polyolefin based. The plastics bolt-on can recover 95+% pure polypropylene and polyethylene plastics for use in the manufacturing of drain pipes, packaging, oils or waxes.   

Research & Development

Since 2009 Fiberight has developed and optimised its technology. The core HYDRACYCLE™ process is now proven.

Ongoing R&D is focused on bolt-ons, their integration, and increasing the percentage of waste that can be fully recycled by our process from 70% to 80% plus.

Bolt-on processes are used to convert the raw materials into sustainable high-value materials for manufacturing.

For example; mixed plastic is recovered, cleaned and separated into its components (polypropylene, polyethylene, polyethylene terephthalate) ready for the production of items such as drainage pipes, outdoor furniture and non-food contact packaging.
