“…Yu et al employed a calixarene La 0.6 Ca 0.4 Co 1− x FexO 3− δ precatalyst to effectively deconstruct medical waste plastic materials into carbon nanotubes and hydrogen at 850 °C. 67 Remarkably, even after 10 consecutive high-temperature cycles, the catalyst maintained the highest yields of carbon nanotubes (245 mg g cat −1 ) and hydrogen (24.92 mmol g cat −1 ) for waste plastic treatment. Through varying the reaction temperature and pre-catalyst composition, they identified the Fe/Co ratio in the precatalyst as a key factor in enhancing reactivity and product selectivity.…”

Significant amounts of fermented food waste are generated worldwide, promoting an abundance of residual biomass that can be used as raw material to extract bioactive peptides, fermentable sugars, polyphenols, and valuable compounds for synthesizing bioproducts. Therefore, generating these high-value-added products reduces the environmental impact caused by waste disposal and increases the industrial economic value of the final products. This review presents opportunities for synthesizing bioproducts and recovering bioactive compounds (employing wastes and byproducts from fermented sources) with several biological properties to support their consumption as dietary supplements that can benefit human health. Herein, the types of fermented food waste and byproducts (i.e., vegetables, bread wastes, dairy products, brewing, and winery sources), pre-treatment processes, the methods of obtaining products, the potential health benefits observed for the bioactive compounds recovered, and other technological applications of bioproducts are discussed. Therefore, there is currently a tendency to use these wastes to boost bioeconomic policies and support a circular bioeconomy approach that is focused on biorefinery concepts, biotechnology, and bioprocesses.

“…In the long-term, changing the energy grid in this direction will result in higher shares of renewable energy in the power mix. In recent years, increased interest has been shown in the application of plasma for hydrogen production [13,14], the catalytic synthesis of ammonia [15][16][17][18], the methanation of CO 2 to synthetic natural gas [19,20], the conversion of CO 2 to alcohols [21], and the production of nanomaterials [22], to name but a few applications. Since plasma is typically characterized by its fast startup [23][24][25][26], plasma-based technologies are of particular interest with respect to their increased use in the demand-side management of power systems.…”
