As global plastic production continues to rise, replacing fossil-based plastics with renewable and biodegradable alternatives has become increasingly urgent. Researchers have now evaluated hemp hurd-based biocomposite films as sustainable substitutes for conventional packaging and mulch films using a full cradle-to-grave life cycle assessment. Published in Journal of Bioresources and Bioproducts, the study demonstrates that these biocomposites maintain mechanical performance comparable to conventional plastics while offering clear environmental advantages. Among the disposal options studied, anaerobic digestion showed the lowest global warming potential due to electricity generation from biogas and the reuse of digestate as a soil conditioner. The results provide practical guidance for integrating agricultural residues into circular bioplastic systems and improving waste management strategies for emerging bio-based materials.

A University of Cambridge study has found that stresses such as systemic racism and socioeconomic disadvantage may sensitise key processes in the body during pregnancy, helping to explain why black women and their babies face significantly higher rates of complication than white women.

Simulations by a team of scientists, including University of Groningen Professor of Artificial Intelligence Davide Grossi, show that an unrestricted flow of information can amplify incorrect ideas amongst like-minded people.

A Concordia-led study finds green alleys can boost biodiversity and social cohesion, but their benefits vary widely depending on design and purpose. Comparing Montreal and Trois-Rivières, researchers show no one-size-fits-all model: resident-driven alleys are more varied, while standardized designs yield more consistent cooling but may better meet infrastructure needs than community preferences.
