TL;DR: Methane yield from the thermophilic pilot scale digestion of 17 types of domestically SS-OFMSW originating from seven full-scale sorting systems indicates that sorting and collection systems in the present study do not significantly affect the amount of methane produced per VS treated.

TL;DR: Co-digestion of sludge from grease traps and sewage sludge was successfully performed both in laboratory batch and continuous pilot-scale digestion tests, and it was seen that the grease trap sludge increases the methane yield without increasing the sludge production.

TL;DR: The amount of methane generated from 1t of collected waste was therefore mainly determined by the efficiency of the chosen pre-treatment technology described by the mass distribution of the incoming waste between biomass and reject.

TL;DR: The overall composition of the collected waste was strongly affected by the collection system (city) and season, while dwelling type had no significant influence.

TL;DR: In this paper, the authors investigated the drivers behind the decision of stakeholders to implement source separation systems as well as the importance of the previously existing pilot areas in the decision-making process, and found that the most important drivers were on the one hand governmental, especially local environmental goals and on the other hand the ambition of the utilities to gain knowledge about future wastewater management and treatment technologies.
