本研究的目的是评估最佳解决方案，不仅考虑到传统的经济活动，而且考虑到环境保护活动，如废物管理和环境投资。为了研究这些活动，我们构建了一个多部门动态宏观经济模型并进行了模拟，该模型包括每个部门的废物产生以及废物减少，回收和最终处置过程。虽然再循环活动比其他废物管理过程，如焚烧和直接最后处置，成本更高，但在回收经济货物方面也有一些经济效益。我们的模拟结果显示，在未来最终处置空间不会严重短缺的情况下，可以预期采用焚化炉工艺来减少最终处置的废物。另一方面，在空间受到严重限制的情况下，再循环过程将成为首选方法，因为废物管理成本将呈指数级上升，而且人们将认识到再循环活动的经济回收效益更为重要。将提供环境控制设备的工业与其他传统制造部门分开的模型版本进行的模拟表明，环境工业在环境改善和经济进步方面具有很大的潜力。
The objective of this research is to evaluate optimal solutions taking into consideration not only conventional economic activities, but also activities for environmental preservation such as waste management and environmental investment. In order to investigate these activities, we constructed and performed simulations with a multi-sectoral dynamic macroeconomic model, which includes waste generation from each sector as well as the waste reduction, recycling, and final disposal processes. Although recycling activities are more costly than other waste management processes such as incineration and direct final disposal, there are some economic benefits in terms of recovery of economic goods. Our simulations revealed that in cases where there will not be a severe shortage of space for final disposal in the future, the incinerator process can be expected to be adopted for the reduction of waste for final disposal. On the other hand, in cases where severe space constraints exist, the recycling process will become the method of choice because waste management costs will become rise exponentially and the economic recovery benefit of recycling activities will be recognized as being much more important. Simulations performed with a version of the model that separates industries supplying equipment for environmental control from other conventional manufacturing sectors demonstrated that environmental industries have a large potential for both environmental improvement and economic progress.
