The recycling of lithium iron phosphate (LiFePO4) batteries from electric and hybrid vehicles was investigated, by applying mechanical pretreatment and hydrometallurgical methods. The aim was to extract lithium (Li) into the aqueous solution and prec...

Geothermal energy is typically produced from underground reservoirs using water as the working fluid to transfer heat energy to surface and eventually to the delivery point. CO2 has been proposed as an alternative working fluid due to its improved mo...

Resource efficiency is one of the basic principles of a circular economy (CE). It can be achieved by finding replacements for natural raw materials using anthropogenic raw materials, including by-products from industrial processes and waste materials...

Given the resistance of local communities to mineral extraction (“Not in My Back Yard” NIMBY), the energy transition and the new global economic model, which presupposes a sharp increase in the production of mineral raw materials, represe...

Regulations for building materials in Greece do not allow for the use of recycled aggregates in concrete. The HERACLES Group, aiming to motivate the adoption of provisions in the national regulation, launched a project to evaluate the safe use of rec...

The extraction of nickel and cobalt from a limonitic laterite sample, derived from a mine area in the Greek island of Euboea, was studied via an acid agitation leach process with nitric acid as the leaching agent, to determine the optimal conditions...

This study presents a hydrometallurgical process for the leaching and recovery of tin from waste-printed circuit boards (wPCBs). The process aims to separate and recover tin from filter dust produced during the crushing of wPCBs in a recycling facili...

The main goal of this study was to validate a circular production route utilizing the waste ash generated during stone wool production in cementitious binders. To achieve this goal, two types of waste ash with different compositions and particle size...

In an increasingly globalized and sustainability-conscious market, the environmental attributes of products consist of the information of primary importance for the sustainable development of manufacturing companies. The aim of the paper is to statis...

This paper investigated the potential of thiosulfate as an alternative to cyanide for gold recovery from pressure oxidation residues. Thiosulfate leaching experiments were conducted under controlled conditions, varying parameters such as initial thio...
