Burning Up the Carbon Sink: How the EU's Forest Biomass Policy Undermines Climate Mitigation

open access: yesGCB Bioenergy, Volume 17, Issue 5, May 2025.
The EU's reliance on forest biomass for renewable energy is weakening its forest carbon sink, with even heavily forested Member States losing their net sink entirely. Despite 2016 modeling that predicts this decline in the sink, EU renewable energy policy treats forest biomass as having zero carbon emissions, conflicting with IPCC guidance.

Ni/PiNe Heterogeneous Catalyst from Biomass Waste: Low‐Loading, Ligand‐Free Suzuki‐Miyaura Cross‐Coupling

open access: yesChemSusChem, Volume 18, Issue 7, April 1, 2025.
A resource recycling strategy led to the definition of a novel low‐cost Ni/PiNe heterogeneous catalyst from urban waste valorization. The catalyst proved impressive efficiency (TON 1140) and high durability under microwave irradiation in catalyzing the Suzuki‐Miyaura reaction for several consecutive runs.
