Boomeco Recovered Wood Grades

Grade	Typical Markets	Typical Sources of Raw Material for Recycling	Typical Materials	Typical Non-Wood Content Prior to Processing	Notes
“Clean” Recycled Wood	A feedstock for the manufacture of professional and consumer products such as animal bedding and horticultural mulches. May also be used as fuel for renewable energy generation in non WID* installations, and for the manufacture of pellets and briquettes.	Distribution. Retailing. Packaging. Secondary manufacture e.g. joinery. Pallet Reclamation.	Solid softwood and hardwood. Packaging waste, scrap pallets, packing cases, and cable drums. Process off-cuts from manufacture of untreated products.	Nails and metal fixings. Minor amounts of paint, and surface coatings.	Some visible particles of coatings and light plastics will remain. Excludes grades below. Is a waste for W.M.Regs* requirements. Does not require a WID installation**
Industrial Feedstock Grade	A feedstock for Industrial wood processing operations such as the manufacture of panel products, including chipboard and medium density fibreboard (mdf).	As Grade A, plus construction and demolition operations and Transfer Stations wood residues.	May contain up to 60% Grade A material as above, plus building and demolition materials and domestic furniture made from solid wood.	Nails and metal fixings.Some paints, plastics, glass, grit, coatings, binders and glues. Limits on treated or coated materials as defined by WID.	The Grade content is not only costly and difficult to separate, it is essential to maintain the quality of feedstock for chipboard manufacture, and for PRN revenues. Some feedstock specifications contain a 5 – 10% limit on former panel products such as chipboard, MDF, and plywood. Excludes Grade D. Is a waste for W.M.Regs* requirements. Does require a WID installation, unless granted an exemption**
Grade C. Fuel Grade.	Biomass fuel for use in the generation of electricity and/or heat in WID** compliant installations. Exported under European Regulation (EC) No 1013/2006 to Germany, Sweden and BENELUX. Can also be recycled in low value particle board for the construction industry.	All above plus Municipal Collections, Recycling Centres Transfer Stations And Civic Amenity Recycling sites.	All of the above plus: fencing products, flat pack furniture made from board products and DIY materials High content of panel products such as chipboard, MDF, plywood, OSB and fibreboard.	Nails and metal fixings. Paints coatings and glues, paper, plastics and rubber, glass, grit. Coated and treated timber (non CCA or creosote).	Suitable only for WID installations*. Material coated and treated with preservatives as defined by WID may be included. Excludes Grade D Is a waste for W.M.Regs requirements.
Grade D Hazardous Waste	Requires disposal at special facilities	All of the above plus fencing, track work and transmission pole contractors.	Fencing Transmission Poles Railway sleepers Cooling tower slats	Copper / Chrome / Arsenic preservation Treatments Creosote	Is a waste for W.M.Regs* requirements. Does require a special WID installation.

Arboricultural, Forestry and Sawmill co-products

Grade	Typical Market	Sources of Raw Material	Typical Materials	Typical Non-wood Content	Notes
Arboricultural Arisings	Landscape and amenity markets and increasingly the renewable energy market	Tree surgeons off cuts and residues	Indigenous and exotic garden and parkland grown conifer and deciduous trees	Stones & grit if not stored on sound concrete or tarmac. Occasionally embedded nails and staples	‘Arboricultural arisings’ is the industry term for all wood and organic residues produced during tree surgery work – chips, branches leaves and needles. Chips are by far the most dominant arising
Virgin Wood Chips	Raw material for paper pulp, chipboard & MDF production. Some used in Amenity Market	Sawmills	Coniferous and Deciduous species	Stones and grit if not stored on sound concrete or tarmac	Most sizable softwood sawmills peel incoming logs to produce debarked chips Deciduous and small softwood mills produce chips with bark
Sawdust	Raw material for chipboard manufacture, Animal bedding, poultry litter and absorbents	Sawmills, joinery works and wood machining industries	Predominantly softwood, but some hardwood including imported exotic species	Stones and grit if not stored on sound concrete or tarmac	Fresh conifer and hardwood sawdust has high moisture content. Sawdust from the joinery and wood working industry is usually dry
Roundwood	Raw material for paper pulp, particle board and the expanding biomass fuel market	Forestry Commission and Private woodland thinning and top section of clear felled trees	Produced from commercially grown conifers and deciduous trees	Grit and dirt if stacked on muddy ground or ride sides	‘Roundwood’ is the accepted trade term for small diameter <150mm trees and upper section of mature trees below 150mmØ
Cordwood	Biomass fuel and domestic firewood	Branch wood from deciduous tree felling & tree surgery residues	From UK grown deciduous trees; but some conifers may be cut as cordwood	Grit and dirt if stacked on muddy ground	‘Cord’ is the traditional unit for firewood billets, equal to 128 ft³ (3.62m³)

Reprocessed wood residue grades

Grade	Typical Market	Sources of Raw Material	Typical Materials	Typical Non-wood Content	Notes
Absorbents	Businesses where liquid spillage is likely	Wood recyclers and Sawmill	Recovered wood fines and sawdust	Mineral dust	Wood based absorbents can be supplied loose or in pellet form
Bark	Landscape, horticultural and leisure industries	Sawmills, wood pulp and particle board manufacturers	Predominantly conifer to make compost, mulch and natural surfacing	Stones and grit if not stored on sound concrete or tarmac	Small quantities of Oak bark is still used to tan hides in the traditional manner to produce quality leather
Biofilter Media	Abattoirs, sewage treatment and rendering works	Wood recyclers, woodland owners and sawmills	Coarse graded shredded wood	Nails, some paint, coatings, small stones and grit	Bespoke specifications required for each filter bed to maximize odour reduction
Compost	Landscape, Agricultural and Horticultural industries	Green residues and civil amenity sites	Grass cuttings, shrub and tree pruning’s, leaves and vegetables	Small stones, grit and fine mineral content	Wide variety of specifications produced from growing media to basic soil conditioners
Granulated Wood	Pet bedding, poultry litter and renewable energy	Wood recyclers, sawmills and wood machining	Recovered wood fines and Sawdust	Mineral dust	Granule size produced to satisfy the end use
Wood Briquettes	Commercial and domestic fuel	Wood recyclers and sawmills	Recycled fines, granulated wood and sawdust	Mineral dust, paint flecks and glue	Compressed to form reconstituted logs, usually <15% moisture content
Wood Pellets	Equestrian & cattle bedding, Pet & poultry litter, Fuel & Absorbents	Wood recyclers, sawmills, joinery and wood machining works	Recovered wood fines, granulated wood and sawdust	Mineral dust, paint flecks and glue	Reconstituted wood cylinders, available in several diameters. Usually <10% moisture content

*Waste Management Regulations – this grade requires a waste management licence (or exemption) until final use, and is subject to waste transfer regulations. The definition as to whether a material is a waste or not is under review (September 2009).

** A Waste Incineration Directive-compliant installation is required to allow this grade to be used as biomass.

There will be some coated or treated wood in all grades, as it is impossible to identify or exclude every particle of such material.
