The compact recycling solution for organic waste

The Carbon Eater ferments manure, food waste and organic by-products into valuable liquid fertiliser – locally, odourlessly and in a climate-friendly way.

High quality

The output is a stabilised, nutrient-rich liquid fertiliser that promotes soil fertility and enables real added value.

Mains independent

The Carbon Eater requires no building permit, no sewer connection and no foundation – simply set it up, connect it and start.

Recyclable

The Carbon Eater processes biogenic waste directly on site, lowering logistics costs and measurably reducing greenhouse gas emissions.

Suitable for all types of organic waste

  • Manure
  • Food waste & leftovers
  • Fruit and vegetable waste
  • Waste from fish and meat processing

Reduce waste costs, recover resources, close cycles

The Carbon Eater turns expensive waste into a valuable resource on site – efficiently, odourlessly and in a climate-friendly manner.

7.300kg

The Carbon Eater can process up to 7,300 kg of organic waste per year and convert it into resources.

14,6t

The Carbon Eater can produce up to 14.6 tonnes of high-quality liquid fertiliser for agriculture every year.

1.200

The system captures methane and produces biogas that can be used for cooking, heating or generating electricity.

How organic waste is converted into resources

Organic waste is fermented in an airtight system. This produces biogas for energy use and high-quality liquid fertiliser for agriculture and horticulture.

Collection & feeding

Permissible organic waste such as manure, food scraps, fruit and vegetable waste, and by-products from fish and meat processing are collected and fed into the system.

Collection

Preparation of input material

Before fermentation, the material is adjusted in terms of moisture and structure to ensure optimal microbial activity. This step ensures stable and efficient fermentation.

Processing

Anaerobic fermentation

In an airtight system, microorganisms convert the waste into biogas and liquid fertiliser in the absence of oxygen. The process is odourless, low-emission and decentralised.

Fermentation

Use of biogas

The renewable biogas produced is collected in the integrated storage facility and is available daily for cooking, heating and sustainable, decentralised energy supply.

Biogas

Harvesting liquid fertiliser

The organic liquid fertiliser contains valuable nutrients (N, P, K, trace elements) and can be applied close to the ground or further processed – to improve the pH value, for healthy soils and higher yields.
