Production of secondary aluminium (Al) currently represents about 70% of total European Al production with a still rising trend and about 50% European final Al demand. The utilization of anthropogenic Al resources as secondary raw materials is therefore a ...
Circular economies produce virtually no waste, as materials are re-used and recycled continuously. It’s a dramatic shift from the current linear economy in which we take, make, consume and dispose – drawing regularly on natural resources to create products ...
We consider a complex recyclable waste collection problem that extends the class of vehicle routing problems with intermediate facilities by integrating a heterogeneous fixed fleet and a flexible assignment of destination depots. Several additional side co ...
This thesis develops a unified framework for modeling and solving various classes of rich routing problems with stochastic demands, including the VRP and the IRP. The work is inspired by the problem of collecting recyclables from sensorized containers in G ...
The volume and composition of Ukraine’s municipal solid waste (MSW) has changed in recent years. The percentage of paper and plastics has increased considerably; consequently, manual separation of these materials from landfills has become necessary. In 201 ...
Food and kitchen waste - omnipresent in every corner of the world serve as an excellent source of value added products owing to high organic content. Regardless of existence of various traditional methods of land filling or biogas production used to harnes ...
Solid waste management in Nigeria is a social and public health concern. Waste problems are more serious in cities as the communities lead a non-indigenous lifestyle with respect to resource consumption and wastage. Nigerian municipal waste has organic bio ...
This study reports the colloidal preparation FeOx, TiO2 and FeOx-TiO2 grafted on polyethylene (PE) films leading to bacterial inactivation. A fast bacterial inactivation was attained by the FeOx-TiO2 compared to the FeOx-PE film due to the interfacial char ...
We introduce a unified modeling and solution framework for various classes of rich vehicle and inventory routing problems as well as other probability-based routing problems with a time-horizon dimension. Demand is assumed to be stochastic and non-stationa ...
We consider a complex recyclable waste collection problem that extends the class of vehicle routing problems with intermediate facilities by integrating a heterogeneous fixed fleet and a flexible assignment of origin and destination depot. Several addition ...
