Alternative building blocks sources for poly (ethylene terephthalate): A short review with socio-economical points of view

open access: yesFrontiers in Materials, 2022
The objectives of circularity are often focused on recycling, but combining use of alternative building blocks such as bio-sourced ones for virgin materials with ability for recycling seems to be a relevant challenge. Unfortunately, the volumes of rather

Development and characterization of eco-friendly starch-based plastic reinforcing tea for packaging applications

open access: yesCurrent Research in Green and Sustainable Chemistry, 2023
Petrochemical-based plastics are posing a threat to human existence because of their toxic nature and slow biodegradation rate. However, biodegradable plastics manufactured from natural ingredients are showing hope. The current work deals with developing

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Bio-based plastics – a sustainable solution to plastic pollution

open access: yes
Global annual plastic production is >410 × 106 tonnes with an annual rate increase of 4%; most of this plastic is non-biodegradable. Bio-based plastics (also known as bioplastics) are formed from polymers created from renewable or recycled raw materials,

Leveraging biogenic resources to achieve global plastic decarbonization by 2050

open access: yesNature Communications
There is a rising urgency to decarbonize plastic production given its high carbon footprint and rapid growth in demand. Here, we highlight pathways for carbon uptake and temporary storage (i.e., net-negative greenhouse gas emissions) for plastics on a ...

A scoping and critical review of properties, standards, and regulations of oxo-biodegradable plastics

open access: yesUniversitas Scientiarum, 2023
Based on recent scientific-technical developments referring to the transformation and biodegradation mechanisms of plastic compounds, progress has been made both in the conceptualization of relevant definitions and in the development of technical ...
