Low environmental impact fibre board products for the construction industry: new designs and commercial delivery for a circular economy

该项目将设计新的复合低密度纤维板（LDF）产品，以满足英国板市场的大部分要求，同时纳入废物/副产品材料，包括寿命结束的LDF。这些将基于LDF的“闭环”制造工艺。LDF在英国的使用量很大（例如，作为地板保护和家具屏蔽）。现有的LDF板产品进口到英国，由木纤维制成，通常含有合成粘合剂。回收、再循环和燃烧的困难意味着大多数废弃的LDF在一次性使用后最终都被填埋。该项目将建立在从废物和副产品材料中回收LDF的制造过程的基础上，以解决LDF产品在（多个）寿命结束时回收的设计，商业和材料加工障碍。它将开发创新的商业模式（例如租赁），使产品能够大规模回收/再利用。它还将开发设计方法，以便能够从低质量来源（如经处理的黑袋废物）中掺入纤维素纤维，使其能够纳入纸板制造过程。

The project will design new composite low density fibreboard (LDF) products that meet the requirements of a large segment of the UK board market whilst incorporating waste/byproduct materials including end-of life LDF. These will be based around a ‘closed loop’ manufacturing process for LDF. LDF is used in high volumes in the UK (e.g. as floor protection and screening through to furniture). Existing LDF board products are imported into the UK and are manufactured from wood fibre often with the inclusion of synthetic adhesive binders. Difficulties in recovery, recycling and combustion mean that most waste LDF ends up in landfill after a single use. The project will build on a manufacturing proocess for LDF from waste and byproduct materials to address design, commercial &materials processing barriers to the recycling of LDF product at end of (multiple) lives. It will develop innovative commercial models (e.g. leasing) enabling the recycling/reuse of product at scale. It will also develop design approaches to enable incorporation of cellulose fibres from low quality sources such as treated black bag waste, enabling them to be incorporated into the board manufacturing process.
