Plywood is an engineered wood product used in the construction industry. Major concerns arelinked to plywood and deforestation, with the legitimacy of the raw timber used in theproduction of plywood under question. China is the largest producer and exporter of plywoodin the world. Approximately 50% of the timber used in Chinese manufactured plywood comesfrom illegal sources. Along with China, other major illegal-logging offending countries suchas Brazil and Indonesia supply Europe with the majority of its plywood demand. Not only isplywood being manufactured with non-certified timber, but the glue itself used to bondtogether the thin wood plies is of a very toxic nature. The negative environmental impact ofplywood is compounded by the fact that its embodied energy is significantly high due to transglobaltransportation of both the raw timber and the finished plywood product.Many end-user issues also exist. For use in formworks, the predominant constructionapplication, plywood sheets must all be meticulously “oiled” by the personnel in order toprevent the concrete permanently binding to the board. However, splintering of the externalskin will almost always occur in some sheets, rendering them unsuitable for further use.Additionally, plywood’s short operational lifespan is compounded due to its inherentweakness to moisture. In a formworks application, the same plywood sheet can be used nomore than 5 times, before being treated as waste. 300,000 tonnes of plywood waste isgenerated annually, most of which ends up in landfill.This project seeks to develop technology to take unwanted low-grade waste plastic, of which>200,000 tonnes is currently sent to landfill in the UK, and turn it into an eco-friendly andcost effective high performance substitute to plywood. The successful exploitation of theEcoPanel technology will result in cumulative revenue >£50m after 5 years on the market.

胶合板是一种用于建筑行业的工程木材产品。主要关切与胶合板和森林砍伐有关，生产胶合板所用原木材的合法性受到质疑。中国是世界上最大的木材生产国和出口国。中国制造的胶合板中使用的木材约有50%来自非法来源。沿着中国，其他主要的非法采伐国家如巴西和印度尼西亚为欧洲提供了大部分的胶合板需求。不仅是胶合板是用未经认证的木材制造的，而且用于粘合薄木板的胶水本身也具有非常有毒的性质。胶合板对环境的负面影响是由于原木和胶合板成品的全球运输而导致的其隐含能量显着增加。还存在许多最终用户问题。对于模板的使用，主要的建筑应用，胶合板板必须由工作人员仔细地“上油”，以防止混凝土永久地粘合到板上。然而，在某些板材中，几乎总是会发生外皮开裂，使其不适合进一步使用。此外，胶合板的使用寿命短是由于其固有的湿度。在模板应用中，同样的胶合板在作为废物处理之前，可以使用不超过5次。每年产生30万吨胶合板废物，其中大部分最终被填埋。该项目旨在开发技术，将不需要的低级废塑料（其中超过20万吨目前被送往英国的垃圾填埋场）转化为生态友好且具有成本效益的胶合板高性能替代品。EcoPanel技术的成功开发将在上市5年后带来超过5000万英镑的累计收入。
