The degradation of two poly(ethylene terephtalate) (PET) samples from urban and marine wastes (PET-u PET-m, respectively) has been studied by comparing their properties with those virgin PET (PET-v) post-condensed for bottle fabrication (PET-ssp). FTIR spectroscopy, DSC analysis, WCA MFI results have confirmed that all residues were degraded. Therefore, the chemical recycling evaluated in order...

Climate change and resource scarcity are just two of the planetary crises that make radical socio-economic essential if human society is to be sustainable. Chemical engineering a skill-set can unique contribution transition, going beyond new technological processes provide system-level understanding economic activities from perspective industrial ecology. This paper provides an example by apply...

Continents ride high above the ocean floor because they are underlain by thick, low-density, Si-rich, and Mg-poor crust. However, the parental magmas of continents were basaltic, which means they must have lost Mg relative to Si during their maturation into continents. Igneous differentiation followed by lower crustal delamination and chemical weathering followed by subduction recycling are pos...

Brain-derived neurotrophic factor (BDNF) plays an important role in the activity-dependent regulation of synaptic structure and function via tropomyosin related kinase B (TrkB) receptor activation. However, whether BDNF could regulate TrkB levels at synapse during long-term potentiation (LTP) is still unknown. We show in cultured rat hippocampal neurons that chemical LTP (cLTP) stimuli selectiv...

• GHG footprints of plastic waste chemical recycling to olefins are quantified. benefits quantified relative incumbent incineration with energy recovery. Chemical provides in the order 0.82 kg CO 2 -eq./kg waste. Future developments further increases from 2030. Dealing heterogeneous – i.e., high polymer heterogeneity, additives, and contaminants lowering greenhouse gas (GHG) emissions productio...

Chemical recycling of plastic wastes can be a useful complement to mechanical achieve the required plastics rates and establish circular economy that is climate neutral resource-efficient. Different mixed are subject future efforts studied under uniform conditions intermediate pyrolysis characterized by medium heating rate temperature.
