Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites Exhibiting Mechanical Enhancement and UV‐C Aging Resistance

Polymer Composites, EarlyView.
Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites. ABSTRACT Polylactic acid (PLA) is a promising bio‐based polymer; nonetheless, its extensive application is still limited by poor fracture toughness, low thermal stability, and strong susceptibility to degradation induced by ultraviolet (UV) radiation.

Bioplastics: an examination of variety, degradation, and environmental effects

Environmental Research Communications
There is considerable confusion about ‘bioplastics.’ They are often touted as ‘greener’ than conventional plastics and may be claimed to be biodegradable and compostable. However, there are a great variety of different products claimed to be bioplastics,

Value‐Added Recycling of Beverage Carton Waste Into Thermoplastic Sandwich Structures With Enhanced Energy Absorption and Damping Properties

Polymer Composites, EarlyView.
Preparation of lightweight composite panels from multilayer beverage carton waste. ABSTRACT Beverage carton waste, a multi‐layer composite of cardboard, polymer, and aluminum, presents significant recycling challenges for conventional recovery technologies. This work presents a manufacturing process‐oriented method that allows shredded beverage cartons

Bioconversion and characterization of watermelon rind waste‐based microcrystalline cellulose: A green alternative to synthetic reinforcements

Polymer International, EarlyView.
Microcrystalline cellulose (MCC) was extracted from watermelon rind using acid hydrolysis. MCC can be efficiently used as reinforcement in biofilms and biocomposites. Abstract The increasing accumulation of agricultural waste from watermelon (Citrullus lanatus) represents a substantial environmental concern, particularly in view of the extensive ...

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Bioplastic from Jackfruit Seed Starch and It Is Potency for Education for Sustainable Development (ESD) in Chemistry Learning

EduChemia
Plastic waste is a severe environmental problem. One solution is with bioplastic from jackfruit seed starch (JS). However, this bioplastic has weaknesses, such as not being heat resistant and having low mechanical properties, so adding chitosan (CH) and ...

Relationship Between Micro‐Level Circular Economy and Sustainable Performance in the Metalworking Industry

Sustainable Development, EarlyView.
ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...

Consistently inconsistent: The false promise of ‘sustainable’ plastics

Cambridge Prisms: Plastics
This perspective explains why the lack of regulation around bioplastics remains a hurdle for the successful development and implementation of a legally binding agreement (the Global Plastics Treaty) by the United Nations Environment Assembly to curb ...
