Marine plastic pollution (MPP) is an urgent environmental and socio-economic problem. MPP amounts to 300 million tons annually, originates largely from land-based sources and severely impacts marine ecosystem, harms livelihoods and causes costs for businesses and governments. Plastics permeate the whole width and depth of seas and oceans, near well-developed coastal zones and equally in remotest corners. This undermines economic and social value of the oceans, particularly in terms of fisheries productivity and tourism. The G20 members, responsible for about two-thirds of global plastic waste, recognize the problem and undertake preventive measures - individually and collectively. Yet, are there efficient, effective and sufficient given the urgency of MPP and the contribution of G20 countries. This article highlights existing policies and identifies further policy options using a custom framework for MPP policy that merges Circular Economy (CE) and life-cycle perspectives.

With the worldwide transformation to a circular and low-carbon economy, the demand for sustainable materials has skyrocketed in recent years. Of various methods, sustainable and biodegradable biopolymers derived from renewable bioresources have received significant interest. Synthetic biodegradable biopolymers offer tremendous advantages over natural biodegradable biopolymers due to their stability, flexibility, and a wide range of achievable properties to fit several applications.

The implementation of circular economy (CE) policies in the management of urban policies have become essential for improving overall quality of life, development of green energy, and environmental management hence improving the image of cities. This research focuses on uncovering the core concepts of CE within urban environments, emphasizing actions that can improve green energy and environmental management. The CE aims to create a closed-loop system by prioritizing practices like remanufacturing, reusing, and recycling, which collectively help decrease resource usage and limit environmental damage.

Saudi Arabia is one of the largest greenhouse gas (GHG) emitters due to its heavy reliance on fossil fuels, has begun taking proactive steps to address climate change under Vision 2030. The initiative aims to reduce the country's GHG emissions. As part of this effort, the government is transitioning to renewable energy (RE) to decrease its dependency on oil and support sustainable environmental development.

Electrocatalytic biomass conversion offers a sustainable route for producing organic chemicals, with electrode design being critical to determining reaction rate and selectivity. Herein, a prediction-synthesis-validation approach is developed to obtain electrodes for precise biomass conversion, where the coexistence of multiple metal valence states leads to excellent electrocatalytic performance due to the activated redox cycle. This promising integrated foam electrode is developed via acid-induced surface reconstruction to in situ generate highly active metal (oxy)hydroxide or oxide (MOH or MO) species on inert foam electrodes, facilitating the electrooxidation of 5-hydroxymethylfurfural (5-HMF) to 2,5-furandicarboxylic acid (FDCA).
