Liquid Waste Recycling

Nearly all liquid waste is recyclable and can be put to good use. Robin Liquid Waste disposal look to alternative greener recycling methods to reduce the impact on the environment and our planet.  

Anaerobic Digestion

Anaerobic digestion (AD) is a series of natural biological processes whereby organic waste material such as food waste is broken down by micro-organisms and converted into energy, known as biogas.

The biogas can then be used in a combined heat and power plant or cleansed of carbon dioxide and injected into the National Grid.

A by-product of the AD process is digestate. Digestate is a stable, nutrient-rich substance that is most commonly used as a renewable fertiliser or a soil conditioner. Our natural biological processes can remove oil disposal immediately, we use our best technologies to recycle waste oil.


Composting is a natural biological process in which organic material is broken down by the action of micro-organisms. Typical materials suitable for composting include, green waste and putrescible wastes with pre-sorting and screening to remove non-compostables, plus other enriched organic waste streams (sewage sludge, agricultural, food processing wastes).

The decomposition process takes place in the presence of air and results in elevated process temperatures, the production of carbon dioxide, water and a stabilised residue, known as humus. A high degree of stabilisation can generally be achieved in 3-6 weeks, however further 'curing' of the humus is normally carried out. For composting to occur in an optimum manner, five key factors need to be controlled; temperature, moisture, oxygen, material porosity and Carbon: Nitrogen ratio.
