Environmental problems resulting from the use of plastics in mass products are becoming increasingly serious, and the exploitation of scarce oil resources also poses unimagined long-term risks. Economic models attempt to demonstrate the effectiveness of regulatory measures, but instead of retaining polluting technologies and reducing market volume, petroplastics in products could be gradually replaced by compensating biopolymers. This study investigates how much of the original market volume is recovered by plastics substitution while maintaining market-related efficiency criteria. To this end, an economic market model is developed and information on estimated damage potential and willingness-to-pay is supplemented by means of a consumer study. The static analyses show that, depending on the estimates, the optimal and most efficient market volume after substitution is between 79.5% and 84.7% of the former market volume in petrochemical goods. The higher the damage estimate, the lower the most efficient bioplastics share, but at least 50% and at most 90.7%. Complete substitution is inefficient and requires consumers to perceive a much higher utility from biopolymers compared to the estimated avoidance of damage. All in all, the biopolymer treatment of synthetic products, such as clothing, is proving to be a promising internalisation technology, but requires further market analysis.

在批量产品中使用塑料导致的环境问题变得越来越严重，对稀缺石油资源的开采也带来了无法想象的长期风险。经济模型试图证明监管措施的有效性，但与其保留污染技术并减少市场量，不如通过补偿生物聚合物来逐步替代产品中的石油塑料。这项研究调查了在维持与市场相关的效率标准的同时，通过塑料替代品回收了多少原始市场容量。为此，开发了一种经济市场模型，并通过一项消费者研究来补充有关估计的潜在损害和付款意愿的信息。静态分析表明，根据估算，替代后，最佳和最有效的市场容量是石化产品先前市场容量的79.5％至84.7％。伤害估计值越高，最有效的生物塑料份额越低，但至少为50％，最多为90.7％。与估计避免损坏相比，完全替代效率低下，要求消费者从生物聚合物中获得更高的实用性。总而言之，对合成产品（如服装）进行生物聚合物处理已被证明是一种很有前途的内部化技术，但需要进行进一步的市场分析。与估计避免损坏相比，完全替代效率低下，要求消费者从生物聚合物中获得更高的实用性。总而言之，对合成产品（如服装）进行生物聚合物处理已被证明是一种很有前途的内部化技术，但需要进行进一步的市场分析。与估计避免损坏相比，完全替代效率低下，要求消费者从生物聚合物中获得更高的实用性。总而言之，对合成产品（如服装）进行生物聚合物处理已被证明是一种很有前途的内部化技术，但需要进行进一步的市场分析。
