Researchers at Monash University have developed a hydrometallurgical process to recover high‑purity critical metals from spent lithium‑ion batteries using greener reagents than conventional strong mineral acids. Led by PhD student Parisa Biniaz and Dr Parama Banerjee, the lab‑scale method targets elements such as lithium, cobalt and nickel from shredded cathode material while minimising secondary waste streams. The approach points to lower‑impact recycling flowsheets that could reduce reliance on primary ore for battery metals and change leach chemistry assumptions in future plant design.

Versarien’s collapse puts its Cementene graphene-enhanced concrete admixture in doubt, raising questions over whether graphene additives can achieve consistent performance, certification and cost benefits in mainstream construction mixes. The UK Supreme Court’s Providence v Hexagon ruling is described as a landmark for late payment law, with implications for drafting and enforcing construction payment terms and adjudication strategies. A young plant hire firm in northeast England is reported to be achieving around 40% pre-tax margins, signalling strong demand and tight fleet management in regional equipment supply.

IStructE has released the Manual for the design of bamboo structures to ISO 22156:2021, a 10‑chapter structural engineering guide covering grading and mechanical properties, seismic and wind design, shear walls, durability and connection design for permanent bamboo buildings up to two storeys. Authored by INBAR Bamboo Construction Task Force members David Trujillo, Kent Harries, Sebastian Kaminski and Luis Felipe Lopez, the manual addresses bamboo supply chains and project management from sourcing through to detailed design. The publication formalises design provisions including fire considerations, aiming to make engineered bamboo a credible low‑carbon option in mainstream practice.
