Laponite Imparts Ultraviolet Shielding Properties in Polylactic Acid/Guar Gum Bilayer Packaging
Polymer Engineering &Science, EarlyView.Production of ultraviolet shielding films based on polylactic acid and guar gum incorporated with Laponite. ABSTRACT PLA films are a sustainable alternative to conventional plastics. However, their high cost and limited optical and mechanical properties present challenges that need to be addressed.

Bioplastic Diffraction Gratings Based on Chitosan Extracted From Crab Shell Waste
, 2023 A bioplastic diffraction grating made of chitosan extracted from crab shell waste is fabricated using simple soft lithography. Bioplastic gratings are replicated from PDMS master grating replicas with groove densities of 600 lines/mm and 1200 lines/mm ...

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.

Journal of Polymer Science, EarlyView.Correlated and spatially resolved small and wide angle X‐ray scattering and vibrational spectroscopy have been used as contrast to image failure regions in polymer blend films. The correlated imaging approach reveals molecular detail of the mechanism of failure and molecular scale insight into an enhanced performance of polylactic acid films blended ...

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 ...

Bioplastic Cleaner Production and Economical Calculation
Bioplastic (polylactide) is mainly produced from starch obtained from potatoes, corn, sugar beets and other plants. Bioplastics are used to replace oil-based plastic in production of products such as plastic bags and bottles.

Sustainable Development, EarlyView.ABSTRACT The bioeconomy has become a component of sustainability strategies addressing climate change, resource scarcity and economic transformation. Despite a growing body of literature, evidence on the environmental impacts of the bioeconomy remains fragmented, heterogeneous and distributed across sectors and regions. This paper provides a systematic

Sustainable Development, EarlyView.ABSTRACT Social innovation (SI) is increasingly recognised as an important enabler of circular economy (CE) transitions. However, existing research offers limited explanation of the processes through which SI operationalises CE principles, as SI and CE have largely evolved in parallel and existing conceptualisations remain predominantly descriptive ...

Naturally coloured poly(3‐hydroxybutyrate)
Coloration Technology, EarlyView.Abstract This study reports an innovative approach for producing intrinsically coloured poly(3‐hydroxybutyrate) [P(3HB)] films by incorporating natural dyes—turmeric, paprika, annatto, beetroot and hibiscus—directly into the fermentation medium of Ralstonia solanacearum RS.
