Turn Slurry into a Cost-Effective Cattle Bedding Alternative with the HBC
)
T-T Agricultural and Environmental, in partnership with Cri-Man, are paving the way for sustainable and cost-effective farming practices by utilising a material that most livestock farmers have in abundance: slurry.
The HBC – which stands for Hygeinizing BioCell – is an aerobic digester that turns separated solid manure into a pasteurised alternative to traditional livestock bedding such as sawdust and sand. This is done through the process of bio-drying (or bio-stabilisation): the aerobic biological degradation of organic substances present in slurry.
This process is highly exothermic (hot, hot and hotter), with the slurry maintaining a temperate of 70°C for at least 60 minutes to evaporate the material’s water content and ensure pasteurisation. The end result is a hygienic, recycled solid material that is sustainable, saves money on traditional livestock bedding and has the added benefit of reducing your on-site slurry storage requirements!
How does it work?
- Raw slurry is collected in the reception pit and kept homogenised by a mechanical Cri-Man TBM mixer.
- A Cri-Man PTS chopper pump feeds the raw slurry up to the separator.
- The separated solid fraction, now above 35% dry matter, then enters the HBC.
- The organic material is then continuously mixed and fresh air incorporated to encourage natural fermentation.
- Anaerobic processes raise the internal temperature to 70°C, enabling full pasteurisation of the product.
- The system will only allow the RMS to be discharged once it is 100% pasteurised.
Quick facts
- All HBC systems are provided with fll UK veterinarian certification
- The HBC can produce up to 20 tonnes of hygienic solids a day.
- Pasteurisation is guaranteed, with the solid matter passing through at 70°C for an hour.
- The resulting bedding consist of up to 60% dry material.
- The HBC is a modular system and can be transported in a 20ft container.
- Separating your slurry reduces its required storage space, freeing up room on your site and reducing the risk of a spill or environmental incident.
- Return on investment is achieved in 3 to 5 years.
There are four HBC models available depending the size of your herd – 250, 500, 100 and 2500. You can find the HBC and an example of the hygienic bedding it produces on T-T’s stand at LAMMA 2025.
