Summary: Valorization of organic wastes through fast pyrolysis is a promising option for reducing pollutants and natural resource consumption. Different olive pomace samples were studied to determine the influence of olive crop location and extraction process on bio-oil product distribution. Optimization of fast pyrolysis conditions showed that chemical composition and fat content of olive pomace have significant effects on product distribution. High lignin content increased phenol production, while cellulose decomposed into carboxylic acids. The use of olive pomace wastes could potentially reduce CO2 emissions with further research and experimental processes.

Summary: Azo dyes are widely used in our daily life and in various industries. The uncontrolled release of these dyes into the environment has become a concern, making their detection in water systems a priority. In this study, carbon dots synthesized from wet pomace were used as probes for the sensitive and selective detection of anionic and neutral azo dyes. The detection capability of these probes for azo dyes in aqueous solutions was demonstrated, and a mechanism for the observed fluorescence quenching was proposed.

Summary: The study investigated the use of cheese whey and olive mill wastewater as feedstocks to produce bacterial cellulose using acetic acid bacteria strains. The composition of organic acids and phenolic compounds was analyzed, and various techniques were used to study the chemical and morphological changes in bacterial cellulose. Cheese whey was found to be the most efficient feedstock, while bacterial cellulose produced in olive mill wastewater had a more well-defined network and smaller fiber diameter. The study also analyzed the chemical structure of the bacterial cellulose and identified different chemical bonds. The high versatility in yield, morphology, and fiber diameters obtained from cheese whey and olive mill wastewater contribute to the development of customized bioprocesses for bacterial cellulose.

Summary: This study investigated the removal of lead from aqueous solutions using biochar derived from olive mill solid and liquid wastes. The results showed that lead adsorption by biochar is influenced by factors such as biochar dose, solution pH, and the presence of competitive ions. Geochemical modelling indicated that ion exchange and lead precipitation are the main reactions controlling its removal.

Summary: The co-culture of yeast and bacteria showed promising results in treating palm oil mill effluents, achieving higher biomass and lipid production, as well as efficient chemical oxygen demand removal. The symbiotic association of the co-culture was also validated through the seed germination index of mung beans, indicating its potential for simultaneous bioremediation of POME.

Summary: The shells of the invasive bivalve Corbicula fluminea were found to be inefficient in adsorbing chemicals from extremely toxic olive oil mill wastes (OOMW). However, the abundance of this resource and its absorption capacity for different contaminants suggest the need for further research on its use as a sorption agent in bioremediation.

Summary: Research in the Chilean Andes has shown that in high-elevation ecosystems, cushion plants, aridity, and UV-B radiation are the major drivers of the distribution, composition, and diversity of soil microbial communities. Factors like pH, total C and N content have a much lower impact on the composition of soil microbial communities in these ecosystems.

Summary: Climate change affects precipitation, temperature, and soil microbial communities, which in turn influence plant species distribution. This study examines the interaction between increased temperature and soil microbes on seed germination in a tree species in the Atlantic rainforest. The results indicate that soil microbial communities play a significant role in seed germination, while the effect of warming is unclear.

Summary: Pharmaceutical residues pose environmental concerns and their removal by conventional treatment plants is generally ineffective and carbon intensive. To achieve zero pollution goals, new approaches and technologies are needed to improve wastewater treatment and reduce the carbon footprint. Emerging low-carbon technologies show promise in achieving high removal efficiencies of pharmaceuticals in wastewater.
