We provide two types of multi-purpose organic compost; green and premium. These composts have been processed under controlled conditions to produce a high quality product, as defined by the British Standards Institution's Publicly Available Specification 100 (BSI PAS100).
Green compost is a natural product made by mixing, stacking and turning biodegradable materials under managed conditions. The compost sold by Keenan Recycling Ltd has been made wholly from plant materials recycled from parks, gardens and households.
Food-derived, or premium, compost is a natural product made by mixing, stacking and aerating biodegradable materials under strictly controlled conditions in an in-vessel composting system with a separate maturation phase. The compost sold by Keenan Recycling Ltd has been made from a mixture of food waste from our commercial food waste collections, along with plant materials and organic waste recycled from parks, gardens and households.
Organic matter in soil is essential for good soil structure, water holding properties, microbial activity and soil health. Our composts are excellent soil conditioners, which can be used for garden compost or for agriculture. They add organic matter to the soils which helps to increase production through a range of benefits, such as:
- Reduced need for bagged fertiliser.
- Reduced nutrient leaching.
- Increased yielding potential.
- Potential to improve drainage in heavier soils.
- Improved water-holding in light soils.
- Reduced erosion risk.
- Better soil structure leading to:
- Greater workability of the soil.
- Increased traffic tolerance.
- Beneficial soil micro-organisms aid:
- Soil aggregation.
- Nutrient recycling.
- Plant disease suppression.
We operate Europe’s largest, and the world’s second largest, In-Vessel-Composting plant which takes co-mingled food and garden waste and turns it into premium grade, PAS 100 compost. It is an accelerated version of the natural composting process where biodegradable waste is fed into large, enclosed chambers with added heat, carefully controlled pH and microbial action to create premium grade compost in three days. Take a look at the individual steps above.
We also use open windrow composting to recycle purely garden waste. The material is shredded and formed into trapezium shaped piles and then monitored for moisture and turned to aerate over eight weeks. This produces a quality compost which is screened and sold to the agricultural or horticultural industry.
