Creating Quality Compost

We have two facilities at our South Lanarkshire site where we create quality compost. Firstly, we recycle combined or “co-mingled” green and food waste in an in-vessel composting system (IVC) and secondly we process pure green waste, both producing high grade compost certified to British Standard PAS100.

In-vessel composting

Our green waste and food derived compost is produced in an in-vessel composting (IVC) system with an additional maturation stage. This four-stage organic process can take up to 12 weeks and is carefully managed to ensure nutrient retention.

Combined food waste and garden waste is collected and delivered by truck to our reception shed. The co-mingled material is then screened to remove fine particles before progressing over a picking station to remove typical contaminants which are non-compostable such as plastic bags, plastic bottles, food wrapping and packaging. The material is then fed into a high-speed shredder to reduce the product down to 40 mm after which it is transferred to one of the 18 vessels on site.

Shredded material is then loaded into an empty vessel and once full the cover is drawn over and the door secured.

Fans introduce air through the bottom of the vessel and extract through pipes in the roof, accelerating the natural composting process. Heat is generated naturally in the process which kills any harmful bacteria, allowing the material to break down to produce compost, there are no additives to this natural process. 

The temperature is continuously monitored in each vessel for quality control to ensure that only good bacteria remain which is key to the nutritious content of the compost. At timed intervals, the compost is then moved to another vessel and the process is repeated.

At the third stage the material is then moved to the maturation area and placed into rows called windrows. The windrows are turned regularly to aerate the compost to ensure that heat is evenly spread throughout. The sequence takes 6 to 8 weeks and each windrow is batch numbered for traceability. During the maturation process any contaminants and rubbish from the material continue are removed.

Once the material has been through the maturation process it is moved to the screening area for the final stage of the process, 20mm and 10mm compost.

All other larger particles of mainly wood are taken out at this time and material has its final clean-up of plastic and rubbish by a wind surfer machine.

Compost can benefit agriculture as a soil amendment and fertiliser. The high organic matter content makes this compost an exceptional means to build up the soil profile.

The finished product is a high quality compost ideal for use as a cost effective alternative animal bedding, its water absorbency can complement or replace straw promoting high animal welfare standards.

The resulting compost can be used in a multitude of applications, including farming, golf courses, tree planting and mine reclamation. With its highly nutritious content our compost helps to produce healthy, vibrant landscapes with sustainable results.

Enva organic compost is a natural product which introduces essential organic matter to soil. It helps to improve soil structure, nutrient content of the soil, water holding properties, produce yield, plant disease suppression.

Our compost is a soil improver and should be mixed with top soil/ peat and not used as a direct planting medium as a replacement for peat or top soil.

The British Standards Institutions 'Publically Available Specification' 100 (BSI PAS 100 or PAS100) provides a baseline quality specification for compost. PAS 100 includes requirements about how materials such as green and green-food waste can be processed. Composts produced by an accredited site under the certification scheme can achieve ‘product status’, which means that they are no longer regulated as wastes.

PAS100 provides strict requirements to make sure that feedstock materials, such as green and green-food waste, are processed in a controlled way. For example, that the materials being composted are passed through an effective sanitisation stage.

An area of our facility is dedicated to the composting of solely garden and green waste. Material delivered to site is shredded down to 80mm before being screened. Screening separates out the material to be composted from more woody material which is blended with other saw mill waste to produce a fuel for bio mass boilers.

Enva organic compost is a natural product which introduces essential organic matter to soil. It helps to improve soil structure, nutrient content of the soil, water holding properties, and increases flower and vegetable yield.
