As one quarter of global energy use serves the production materials, more efficient these materials presents a significant opportunity for mitigation greenhouse gas (GHG) emissions. With renewed interest policy makers in circular economy, material efficiency (ME) strategies such as light-weighting and downsizing lifetime extension products, reuse recycling appropriate choice are being promoted. Yet, emissions savings from ME remain poorly understood, owing part to multitude uses diversity...

Abstract Material production accounts for a quarter of global greenhouse gas (GHG) emissions. Resource-efficiency and circular-economy strategies, both industry demand-focused, promise emission reductions through reducing material use, but detailed assessments their GHG reduction potential are lacking. We present global-scale analysis efficiency passenger vehicles residential buildings. estimate future changes in flows energy use due to increased yields, light design, substitution, extended...

Scenario-based assessments are a useful tool to explore unknown futures and inform decision makers the public of consequences different courses action. Scenario developments in industrial ecology have focused on disparate components socioeconomic metabolism case studies, few efforts comprehensive cumulative scenario formulation documented. Many important, empirically derived relationships between material cycles, end-use services, energy use relevant global modeling efforts, for example,...

A transition to electric vehicles and renewable energy is currently underway but may not be rapid enough in order reach ambitious climate change mitigation targets. Therefore, additional, preferably instantaneous, measures are needed for quick emission reductions, which where material efficiency (ME) could constitute a promising solution. ME strategies include limited vehicle lightweighting through substitution, increased recycling of materials, reuse remanufacturing components, downsizing...

Abstract Material production accounts for 23% of all greenhouse gas emissions. More efficient use materials—through decoupling services that support human well‐being from material use—is imperative as other emission mitigation options are expensive. An interdisciplinary scientific assessment efficiency and its links to service provision, cycle management, climate policy is needed identify effective strategies help design the framework required their implementation. We present resource...

Abstract Deep eutectic solvent (DES) has recently been attracting great interest for its role in isolating nanocellulose owing to distinct advantages of biodegradability, low toxicity, and recyclability. Lignin‐containing cellulose nanocrystals (LCNCs) obtained using DES pretreatment led an improvement the production nanomaterials. Understanding potential environmental impacts this novel technology at laboratory scale provides important insights improve sustainability full future. This study...

The manufacture of goods from oil, coal, or gas to everyday consumer products comprises in more less all cases at least one catalytic step. Compared conventional hydrothermal catalysis, electrocatalysis possesses the advantage mild operational conditions and high selectivity, yet potential energy savings climate change mitigation have rarely been assessed. This study conducted a life cycle assessment (LCA) for electrocatalytic oxidation crude glycerol produce lactic acid, most common...

Plastic pollution has posed significant impacts on the ecosystem. While biodegradable transparent cellulose films are considered ideal alternatives, they still grapple with issues of high energy consumption and low production efficiency. In this study, we proposed a water-induced fiber deswelling strategy to expedite fabrication from wood pulp. Raw fibers were firstly disintegrated into micro-sized via cold alkali swelling mild mechanical blending. Subsequently, water was introduced govern...

Chitin nanofibrils (ChNF) sourced from discarded marine biomass are shown as effective stabilizers of carbon nanomaterials in aqueous media. Such stabilization is evaluated for nanotubes (CNT) considering spatial and temporal perspectives by using experimental (small-angle X-ray scattering, among others) theoretical (atomistic simulation) approaches. We reveal that the coassembly ChNF CNT governed hydrophobic interactions, while electrostatic repulsion drives colloidal hybrid ChNF/CNT...

Conventional phototrophic cultivation for microalgae production suffers from low and unstable biomass productivity due to limited unreliable light transmission outdoors. Alternatively, the use of a renewable lignocellulose-derived carbon source, cellulosic hydrolysate, offers cost-effective sustainable pathway cultivate heterotrophically with high algal growth rate terminal density. In this study, we evaluate feasibility hydrolysate-mediated heterotrophic (Cel-HC) by performing economic...

Reclaimed asphalt pavement (RAP) is a widely used end-of-life (EoL) material in pavements to increase the circularity. However, performance loss due using RAP binder layer often requires thicker layer, leading additional usage, energy consumption, and transportation effort. In this study, we developed parametric probabilistic life cycle assessment (LCA) framework robustly compare various designs incorporating recycled materials. Our built upon thermodynamic physical principles reveal complex...
