Recycling Technologies' process is capable of chemically recycling plastic waste. We are determined to reduce the amount of plastic that is either landfilled or incinerated. More than a quarter of the UK's 3.2MT (Million Tonnes) of plastic waste is landfilled because of its contamination with organic material or other plastics. The challenge is to find a way and recover the plastic from this waste stream and reduce the ever-increasing plastic pollution. This project aims to take on this challenge!Our technology, RT7000 is capable of processing the recovered plastic via thermal cracking into an ultra low sulphur hydrocarbon product branded as Plaxx. Plaxx is a synthetic equivalent of crude oil. It can be used as a low sulphur fuel or chemical feedstock (naphtha) to make new plastics.Municipal waste at Material Recovery Facilities (MRF), food contaminated plastic packaging waste from Anaerobic Digestion (AD) plants and Recovered Plastic Litter (RPL) in water treatment facilities are some of the largest sources of plastic waste.We can use smart optical sorting techniques to pick up and separate the plastic from streams of waste from a MRF. In doing so, we can divert the plastic away from incineration and reduce its CO2 impact.Enzyme-based biological cleaning system can be used on AD and RPL waste to break down the organic contamination. In addition to its green and sustainable credentials, enzymatic degradation is relatively cheap and it releases soluble and fermentable sugars that can be re-cycled for other processes.The technologies (optical and enzyme) can be combined together to give RT the ability to accept a wide variety of contaminated waste into its core technology. Once the contamination is processed using a pre-treatment module, the separated plastic waste can be processed using the RT7000. This combined approach will allow UK to reduce landfilling, increase its recycling rates and develop innovative technologies to handle contaminated plastic waste.Furthermore, the diversion of each tonne of plastic waste away from Energy from Waste (EfW) plants and converted into Plaxx fuel creates up to 2.5 TCO2e savings. This saving for 7000 tonnes of plastic waste is equivalent to the emissions of more than 3,500 cars every year!!!!!

回收技术公司的工艺能够化学回收塑料废物。我们决心减少填埋或焚烧的塑料数量。英国320万吨塑料垃圾中有超过四分之一是由于有机材料或其他塑料污染而被填埋的。我们面临的挑战是找到一种方法，从废物流中回收塑料，减少不断增加的塑料污染。这个项目就是为了迎接这个挑战！我们的技术RT 7000能够通过热裂解将回收的塑料加工成品牌为Plaxx的超低硫烃产品。Plaxx是一种合成的原油。它可以用作低硫燃料或化学原料（石脑油）来制造新的塑料。材料回收设施（MRF）的城市废物，来自厌氧消化（AD）工厂和废弃塑料垃圾（RPL）的食品污染塑料包装废物水处理设施中的垃圾是塑料垃圾的最大来源之一。我们可以使用智能光学分选技术从垃圾流中收集和分离塑料一个MRF这样，我们可以将塑料从焚烧中转移出来，减少其二氧化碳排放。酶基生物清洁系统可用于AD和RPL废物，以分解有机污染物。除了其绿色和可持续的证书，酶降解是相对便宜的，它释放的可溶性和可发酵的糖，可以再循环用于其他过程。这些技术（光学和酶）可以结合在一起，使RT能够接受各种污染废物进入其核心技术。使用预处理模块处理污染物后，可使用RT 7000处理分离的塑料废物。这种综合方法将使英国能够减少垃圾填埋，提高回收率，并开发创新技术来处理受污染的塑料废物。此外，将每吨塑料废物从废物能源（EfW）工厂转移并转化为Plaxx燃料可节省高达2.5 TCO 2 e。这7000吨塑料废物的节省相当于每年3,500多辆汽车的排放量！
