\u2022 There are few completely sustainable new materials. Most materials have an environmental impact through manufacture and transport, quite apart from their impact on scarce mineral or natural resources.<\/p>\n
\u2022 Avoid specifying virgin materials, identifying instead materials that are reused, repurposed, rented, recycled or zero carbon. In particular, virgin steel has a very high carbon footprint and recycled equivalents will greatly reduce emissions.\u00a0<\/span><\/p>\n \u2022 Only once sources of reused and recycled materials have been explored, should theatres use virgin materials in their productions. If they do, it is important to make sure they are sourced as sustainably as possible.<\/p>\n \u2022 If raw (virgin) materials are required, specify based on lowest possible carbon option. This can be checked using free online Environmental Product Declaration databases or in manufacturer information. Natural materials typically perform better than man-made or synthetic \u2013 such as timber in preference to metals and plastics. Plastics can be reusable, recyclable or compostable<\/p>\n \u2022 Use natural materials as alternatives: for example, varnishes, dyes and lacquers, raw oils, petroleum free wax, PVA adhesives, bio paints with low VOC content, biodegradable or paper-based tapes and chalk.<\/p>\n \u2022 Timber has a substantially lower carbon footprint than steel and other structural materials typically used on shows. However, it is important to specify and source it as sustainably as possible.\u00a0<\/span><\/p>\n \u2022 Timber is more likely to be sustainably forested and sourced if it has FSC or PEFC certification. Record the procurement route and certification and consult the UK Government Timber Procurement policy for more information on certification.\u00a0<\/span><\/p>\n \u2022 The following is an example of an inclusive specification clause:\u00a0<\/span><\/p>\n All timber and wood based products must be from legal and sustainable sources, as defined by the UK Government Central Point of Expertise on Timber (CPET), be sourced from European forests, and be delivered to the workshop with full chain of custody.\u00a0<\/span><\/i><\/p>\n Chain of custody schemes recognised as meeting the above include:\u00a0<\/span><\/i><\/p>\n \u2022 Programme for the Endorsement of Forest Certification (PEFC)<\/i><\/p>\n \u2022 Forest Stewardship Council (FSC)\u00a0<\/span><\/i><\/p>\n \u2022 Grown in Britain (GiB)<\/i><\/p>\n PEFC<\/a><\/p>\n FSC<\/a><\/p>\n GiB<\/a><\/p>\n \u2022 Chain of Custody certification is a way of tracking certified material from the forest to the final product to ensure that the material contained in raw timber or timber-based products\u00a0 <\/span>can be traced back to certified forests.<\/p>\n \u2022 UK and European timber:<\/p>\n – has had to travel less far<\/p>\n – is more likely to have been forested sustainably<\/p>\n – is easier to validate through full chain of custody<\/p>\n Specifying PEFC, FSC or GiB-certified timber from European sources is most likely to produce wood that\u2019s been grown and forested sustainably.<\/p>\n \u2022 Request Environmental Product Declarations (EPDs) from timber suppliers to compare carbon footprints (\u2018the equivalent CO2 value\u2019) of different options. You can quickly check and compare EPDs for many timber products using the ICE Inventory of Carbon and Energy database. Typically, Particle Board, Glulam, Laminate timber, and Fibreboard have lower carbon footprints than plywood, chipboard or OSB, but this varies depending on the product.<\/p>\n \u2022 Confirm with suppliers or in manufacturer specifications that all structural timber meets, as a minimum, Formaldehyde release class E1 to BS EN 14080:2005 and has a confirmed absence of prohibited wood preservatives\/biocides to BS EN 13986:2004.\u00a0<\/span><\/p>\n \u2022 64% of particleboard and OSB is UK-produced, with the remainder mostly coming from mainland Europe. No plywood is produced in the UK, with only 20% coming from mainland Europe.<\/p>\n \u2022 The manufacture of metal involves intensive use of energy. It is therefore essential to avoid the use of virgin metal products as much as possible. Reusable scaffold-type products for framing sets are available, such as Layher.<\/a><\/p>\n \u2022 When metal products are needed, make sure you use only recycled steel or aluminium. Work and coat it as little as possible so as to facilitate reuse afterwards.<\/p>\n \u2022 Where there is a functional requirement for fabrication in new metals, steel should be preferred to aluminium, which has particularly high embodied energy. Fabrication in aluminium also consumes more energy than steel.<\/p>\n \u2022 Adhesives make it much harder to salvage and reuse materials after each production. Removeable fixings should be used whenever possible. If use of adhesives cannot be avoided, use traditional adhesives, for example, naturally-based adhesives such as Lignin, Soya Protein, Brettstapel, dowellamination etc.\u00a0<\/span><\/span><\/p>\n \u2022 Supplier\/manufacturer information should be recorded to facilitate these materials being reused or recycled later. This should include data sheets, or any restrictions noted in product specifications that might be imposed by adhesives, treatments and finishes that would affect particular methods of recycling or use as a fuel in gasification, biochar, anaerobic storage or other process.\u00a0<\/span><\/span><\/p>\n \u2022 For battery use and disposal click here<\/a>.<\/p>\n Le Mark Gaffer Tape<\/a><\/p>\n Stage Set<\/a><\/p>\n Flints<\/a><\/p>\n See Costumes, Props and Lighting for other sustainable alternatives.<\/i><\/p>\nSpecifying Materials<\/b><\/h3>\n
