This single-pot reaction scheme could open the path to recycling used tires
Recycling vehicle tires is complicated because the rubbers used (including butadiene and polyisoprene) are highly cross-linked, and because pyrolysis-based recycling of the rubbers generates environmentally hazardous compounds like benzene and dioxins. Now, researchers at the University of North Carolina at…
First-of-its-kind project converts datacenter waste heat into biomass
Data4 (Paris, France), leading European datacenter operator, and the Fondation de l’Université Paris Saclay announced the launch of a groundbreaking proof-of-concept project aimed at transforming heat from its servers into biomass. This ambitious project, deployed at its Marcoussis, France site,…
Chlor-Alkali Process Systems
Design considerations to ensure a safe, effective piping system A naturally occurring element, chlorine serves as the basic building block for some of the most critical health and safety items used in everyday life, such as drinking water treatment, waste…
Industrial water reuse and recycling
Why measurement matters when every drop counts Considering the growing global demand for freshwater, industries worldwide are increasingly turning to water recycling and reuse technologies as vital components of their sustainability strategies. Technology advancements are driving the ability to recycle…
Co-Current vs. Counter-Current Spray in Gas Cooling Applications
A CFD-Based Performance Analysis Cooling hot gas is necessary in many industrial processes to protect equipment and ensure employee safety. Daniel deLesdernier, Advanced Spray Engineering Services Manager at BETE, presents a computational fluid dynamics (CFD)-based analysis of co-current and counter-current…
Two-pronged approach recycles textile waste while also producing glucose
Glucose is a key pillar in producing bio-based alternatives to conventional chemicals, but finding industrially viable, non-food-competitive sources for glucose has proven challenging, due to the difficulty in obtaining glucose from hemicellulosic materials, such as woody biomass, in a cost…
Short-loop battery recycling uses vegetable-oil nanoemulsion
Efficient and sustainable recycling of lithium-ion batteries is a crucial element in electrifying transportation. Black mass is a mixture of cathode and anode materials remaining after disassembly and shredding of end-of-life lithium-ion batteries (LIBs). Many valuable materials, including lithium and…
An integrated process makes valuable mid-chain carboxylic acids from organic waste
A dual process strategy bridging fermentation and electrochemistry is enabling the production of mid-chain carboxylic acids (MCCAs) — important and valuable precursors to a number of products — using inexpensive organic waste streams from breweries, distilleries and dairies. Developed by…
Selective silica removal makes for better bauxite beneficiation
The extraction of alumina from bauxite is significantly impacted by the silica content of the ore — specifically the presence of silica in kaolinite (Al2Si2O5(OH)4). This is because traditional bauxite-beneficiation methods, such as washing, flotation and particle-size separation, also typically…
Seawater-derived solids can serve as carbon-negative components of concrete
Aggregate — solid materials like sand, gravel and crushed stone — is combined with cement to make concrete, the world’s most widely used human-made material. But sand is in short supply, so there is a need for alternate materials to…
