5.5. Financial costs
Unlike the previous diagrams, the impact from the waste management is greater than the compensatory system (Fig. 7). Landfilling is the most expensive waste treatment due to the alternative cost for fulfilling the functional units (mainly heat). The total costs are slightly higher for recycling of plastic compared to incineration, due to the relatively low value of recycled plastics, while the BioCar scenario is marginally cheaper, due to the high cost of gasoline, the alternative car fuel. In the waste management system, the dominant costs are for collection and incineration. Collection has a larger economic impact than environmental impact, although it does not vary substantially between scenarios. Incineration is costly as the majority of waste is incinerated in all scenarios except in the landfill scenario. For that scenario, landfill costs, including landfill tax, are naturally dominant
