Innovative approaches are required to transition from a linear to a circular (bio)economy. Natural plastic alternatives, such as polyhydroxyalkanoates (PHAs), have great potential to promote this transition. In this study, we demonstrate the feasibility of converting solid waste animal fat (WAF) into the PHA copolymer poly(hydroxybutyrate-co-hydroxyhexanoate) (P(HB-co-HHx)) via bacterial fed-batc…

Porous activated carbon-based solid acid catalysts (AC‑SACs) have gained significant attention as promising materials for biomass conversion due to their high surface area, tunable porosity, and strong acidic functional groups. Biomass conversion is essential for the sustainable production of biofuels, including biodiesel, and other value‑added chemicals, offering an alternative to fossil-based r…

Intensification of media components can effectively improve biochemical production by reinforcing the metabolic capacity of engineered strains. Here, we present a citrate-enabled medium intensification strategy for sustainable l-theanine biomanufacturing in Corynebacterium glutamicum. Recombinant strains expressing heterologous theanine synthases were constructed using a strain expressing l-gluta…

Aquaponics is a recognised food system for its circular nutrient management potentiality, as it redirects aquaculture waste into plant production. However, current practices still fall short of closing nutrient loops, with substantial losses occurring through dissolved effluents and solid waste. This review examines strategies to reduce losses, recover nutrients, internally recycle dissolved stre…
