Transaction Costs in Collective Waste Recovery Systems in the EU [PDF]
arXiv, 2018 The study aims to identify the institutional flaws of the current EU waste management model by analysing the economic model of extended producer responsibility and collective waste management systems and to create a model for measuring the transaction costs borne by waste recovery organizations.

Feasibility of Direct Disposal of Salt Waste from Electochemical Processing of Spent Nuclear Fuel [PDF]
arXiv, 2017 The US Department of Energy decided in 2000 to treat its sodium-bonded spent nuclear fuel, produced for experiments on breeder reactors, with an electrochemical process. The metallic waste produced is to be cast into ingots and the salt waste further processed to form a ceramic waste form for disposal in a mined repository.
