Abstract:
... The synthesis of citronellal, an added-value chemical for perfumery, was performed through selective and green hydrogenation of citral into citronellal in water. Aqueous suspensions of spherical ammonium-capped palladium nanoparticles with sizes around 3 nm selectively reduced the conjugated carbon–carbon double bond. An excellent selectivity up to 97% in citronellal was achieved at complete conve ...

Abstract:
... This study aimed to verify if microwave hydrodiffusion and gravity (MHG) could efficiently extract anthocyanins from strawberries and raspberries with low environmental impact and costs. Our findings revealed that it was possible to extract 69 and 64% anthocyanins from the strawberries and raspberries in a single extraction step, respectively. When the co-product (product remaining after extractin ...

Abstract:
... The monoallylation of aniline to give N-allyl aniline is a fundamental transformation process that results in various kinds of valuable building block allyl compounds, which can be used in the production of pharmaceuticals and electronic materials. For decades, sustainable syntheses have been gaining much attention, and the employment of allyl alcohol as an allyl source can follow the sustainabili ...

Abstract:
... Guayule (Parthenium argentatum A. Gray) exploitation has so far been focused on the production of rubber, but until now was unable to compete commercially, as other guayule co-products have not been equally considered for exploitation. However, to successfully exploit one of these co-products, the guayulins, it will be necessary to establish a robust resin extraction method that maximizes the yiel ...

Abstract:
... In view of clean environment, the industry needs to address multiple demands at different levels of production and processes via the sustainable approach including recycling or smart use of produced waste. On the other hand, a development and success of green energy requires the crucial materials synthesized via efficient, sustainable methodology. Herein, the green, simple, easily scalable, fast, ...
... Brewers' spent grain (BSG) is a brewery co-product rich in phenolic compounds which only within Europe, 3-4Mt is generated annually. This study aims to sustainably isolate low-molecular-weight phenolic compounds from Belgian BSG using a microwave-assisted method (MW). Two types of BSG (from light and red malted barley grains) were subjected to MW at 600 and 800 W for 5, 15 and 30 min. MW showed a ...

Abstract:
... One of the main social and economic challenges of the 21st century will be to overcome the worlds’ water deficit expected by the end of this decade. Microalgae based wastewater treatment has been suggested as a strategy to recover nutrients from wastewater while simultaneously producing clean water. Consortia of microalgae and bacteria are responsible for recovering nutrients from wastewater. A be ...

Abstract:
... Fruit peel (i.e. pericarp + mesocarp) is the most abundant by-product of the agri-food pomegranate processing chain. In recent decades, pomegranate fruit peel is attracting a lot of attention due to the presence of bioactive molecules suitable to be used in the production of food supplements. This study aimed at investigating and characterizing the nutritional and nutraceutical quality of the peel ...
... The phyllosphere, defined as the aerial parts of plants, is one of the most prevalent microbial habitats on earth. The microorganisms present on the phyllosphere can have several interactions with the plant. The phyllosphere represents then a unique niche where microorganisms have evolved through time in that stressful environment and may have acquired the ability to degrade lignocellulosic plant ...

Abstract:
... Mexico is the sixth-largest producer of sucrose worldwide. Therefore, evaluating the environmental impacts of Mexican sugar and proposing impact mitigation strategies is of high importance since this would support better environmental performance and foster competition within the sector. However, the technological variability that occurs between farms and sugar mills, together with the different t ...
... Biochar is produced by thermochemical conversion of biomass-based feedstocks and is a co-product of gasification and pyrolysis processes, which produce gas and liquid phase fuels. There is growing interest in using biochar as a catalyst as it is sustainable, inexpensive, and its properties can be modified to produce a biochar catalyst with a wide variety of surface conditions. This paper examines ...

... Emergy accounting in a system with co-production branch is of great scientific interest since each branch corresponds to a different transformity value. In previous studies, limitations associated with emergy accounting in co-production systems have been highlighted where some “inputs” have to be added to obtain a “useful” product from a “co-product” – giving rise to inaccuracies in the emergy acc ...
