Composting has no environmental advantages compared... Cardboard recycling is comparable to incineration. A better alternative to landfill disposal is incineration? Environmental impact, fuel consumption and costs are calculated for the entire lifecycle from the households, until the waste is treated and the by-products have been taken care of. Source separation of food waste may increase transport emissions due to intensified collection. Recycling of plastic has slightly less environmental impact and energy consumption than incineration. To stop landfill disposal is the most important measure to take to decrease environmental impact. Deposition at landfill has been compared to energy recovery, recycling of material (plastic and cardboard) and recycling of nutrients (in food waste)! There are environmental advantages if the waste is digested and the biogas substitutes diesel in busses. Instead the waste should be used as a resource, thereby substituting production from virgin resources.
