要使塑料废物的化学回收可行，回收过程中产生的化学产品需要找到市场。美国化学制造业的网络模型被用来评估来自聚乙烯热裂解的化学产品在目前的美国化学制造业中可能找到市场的成本点和程度。网络模型确定了模拟的工业网络利用热解产品的成本点，以及哪些流程被再生材料的供应所取代。模拟的特点是，化学制造网络中的大量过程受到来自聚乙烯回收的相对少量产品的可用性的影响。在聚乙烯回收的情况下，扩大产能以有效利用回收材料的资本成本要求高于热解过程所需的资本成本。这表明，在回收塑料的技术经济分析中，确定可在产能过剩的工艺中利用回收材料的方案将是一个关键的考虑因素。
For chemical recycling of plastic wastes to be viable, chemical products generated in recycling need to find markets. A network model of the U.S. chemical manufacturing industry was used to assess at what cost points, and the extent to which, chemical products from thermal pyrolysis of polyethylene might find markets in the current U.S. chemical manufacturing industry. Network modeling determined the cost points at which the simulated industry network utilized the thermal pyrolysis products and which processes were displaced by the supply of recycled materials. The characteristic feature of the simulations is the large number of processes in the chemical manufacturing network that are impacted by the availability of a relatively small number of products from polyethylene recycling. In the case of polyethylene recycling, the capital cost requirements for expanding capacity to effectively utilize the recycled materials is greater than the capital required for the pyrolysis process. This suggests that identifying scenarios where recycled materials can be utilized in processes that have excess capacity will be a critical consideration in techno-economic analyses of recycling plastics.
