Green garden bin waste is taken to an In Vessel Composting facility. The waste rots down very quickly in the enclosed space and gets very hot, killing off any harmful bacteria that may be in cooked meat or other food waste. The compost produced is low quality, however, and is rarely useful for gardening. It is often used in landscaping, and to help cap landfill sites.
Garden waste collected at household waste recycling centres (tips) is normally taken to a conventional compost facility, where the waste rots down more slowly and at lower temperatures. This means that it cannot be used to process food waste. The process is cheaper and the compost produced is higher quality than In Vessel compost. It is typically used by farmers.
