1. Landfill site
The Binn Landfill operated as a non-hazardous disposal facility from 1994 until its closure in 2015. It’s closure represents the success of Scottish recycling with disposals to such sites dropping sharply over recent years. The site must now be restored to a finished land profile. This involves capping the site to prevent the release of landfill gas and then covering the site with suitable growing media to support the establishment of plants. Future use of this site is likely to be for increasing biodiversity on the site and possibly for second-generation biofuel crop production. The site will continue to produce electrical energy for export to the grid for many years, from it’s 3 1MW landfill gas engines.
2. Wood recycling operation
Suez Environnement operate this facility to recover waste wood for use as a fuel in the RWE Biomass Energy facility at Markinch, Glenrothes. Waste wood is delivered to the site where it is screened for contaminants, shredded and any metals removed.
3. Food waste recycling
- Food waste reception hall
- In-vessel composting
- Primary and secondary anaerobic digestion tanks
- Compost maturation shed
- Digestate storage tank
Food waste can either be composted under controlled conditions or digested in anaerobic digestors. In both cases heat is used to sterilise the material. This ensures that the finished material, which can be used as fertiliser, is pathogen free and presents no risk to animal health.
In recent times there has been a growing trend towards anaerobic digestion for food waste, as a higher value process, as it produces bio-methane, which can be converted to energy. The current anaerobic digestion (AD) facility operated by Earnside Energy Ltd processes about 15,000 tonnes of food waste from households and businesses across Tayside and Fife every year.
The AD facility is about to undergo a refit to upgrade its capacity to 30,000 tonnes of food waste treatment capacity per annum. The bio-methane is combusted in a gas engine and the electricity exported to the national grid. The finished digestate is then pasteurised (sterilised), stored and used on local farms as a fertiliser.
Once the site is upgraded, this material will support local agriculture in a good example of circular economy nutrient use. The site will continue to compost materials not suitable for use in an AD system. This material is a high nutrient content compost fertiliser suitable for use in agriculture once it is matured.
The Binn Group have a separate site which processes green waste only in outside windrows. The resulting compost is supplied free of charge to Perth and Kinross Council for use by the general public.
4. Soils and aggregate recycling
The Binn Group collect waste materials across a wide geographic area. Materials are also delivered to the site for treatment from companies as far as Aberdeen, Inverness, Edinburgh, Glasgow and the Central Belt. These waste materials which include crushed concrete, bricks and stone, top-soils, sub-soils and sand have various uses in construction, road making and as components in new soils for land restoration. The Binn Group form part of on-going research into the production of new ‘Technosols’ to improve the standards of derelict land restoration.
5. Main waste reception (Industrial Waste)
This is the heart of the Binn Group recycling operation. Whilst we collect significant quantities of separated material from businesses, as required by the Zero Waste (Scotland) Regulations 2012, we also separate further recyclate from trade (commercial), industrial and construction mixed waste sources.
The materials recovered in this way include:
- Plastic films
- Rigid plastics
- Ferrous and non-ferrous metals
The main waste reception area deals with our heavy skip wastes and processes this material through two different picking and separation lines. The recovery of material in this way significantly reduces the material that must be disposed of.
6. Trade (commercial) waste reception and recycling
Trade waste is similar to household waste and arises from shops, hotels, academic establishments, sporting facilities and public events. This material is different from the heavy industrial material we process so it is processed in a different area to recover plastic films, metals and cardboard.
The residual (non-recyclable) material from both the trade and industrial processing areas used to go to landfill. The Binn Group have now developed a new process to convert this material into Solid Recovered Fuel (SRF) a high specification waste fuel for use in cement kilns. Residual material not suitable for conversion into SRF is baled and exported as Refuse Derived Fuel (RDF) for use in European incinerators where the material provides heating for district heating schemes. The Binn Group owns and operates the only advanced SRF facility in Scotland.
7. Dry and mixed recycling (DMR)
This facility is operated by SITA UK Ltd and processes kerbside collected mixed dry household recyclates, collected by Perth and Kinross Council and other local authorities.
The materials recovered in this way include:
- Metals (ferrous and non-ferrous)
- Plastic bottles
8. SRF Facility
This facility commenced its operational phase in march 2015 and produces a high quality waste fuel comprised mainly of non recyclable plastics, paper, cardboard, textiles and wood. The produced fuel has a high calorific content and is commonly used as a substitute fuel in cement production. The process involves drying the waste using hot air produced by a biomass boiler. The dried material is then processed to remove metals for recycling and other materials not suitable as fuel. The material is then shredded before being baled and wrapped in polythene film ready for storage and export.
9a/9b. Maintenance and engineering
The Binn Group operates a fleet of over 50 collection vehicles of different types and a wide range of heavy plant from earth moving machinery to forklifts. We have our own vehicle maintenance facility and our own fabrication workshop.
10. Main Office
The Binn group offices hold all of our administration, finance and senior management team including our Board Room. With a strong focus on environmental and health and safety compliance the main office is the organisational centre of our business.
