Special Issue Information

Dear Colleagues,

Environmental chemistry is one of the disciplines that has developed the most in recent years, allowing knowledge of the possible mechanisms of modification and/or transformation of pollutants in the environment. Applying this knowledge enables the detection of new environmental problems and the search for possible solutionsActivities such as mining, use of fossil fuels, intensified agriculture, industrial waste discharges, and urbanization have been developing without control in many parts of the planet, contributing significantly to the deterioration of ecosystems and human health and causing many sustainability problems. Therefore, a good diagnosis of an environmental problem will serve as support to propose sustainable and viable environmental remediation strategies.

This Special Issue aims to present innovative research on environmental chemistry, as well as the implementation of sustainable technologies for the remediation of environmental matrices and new strategies for the recovery of waste. Topics include but are not limited to the following:

  • Environmental monitoring
  • Environmental pollution and toxicology
  • Environmental pollution and climate change
  • Sustainable use of natural resources
  • Sustainability in environmental remediation
  • Innovations in water and wastewater treatment
  • Valuation of agro-industrial waste
  • Application of advanced oxidation processes degradation of organic   compounds
  • Soil remediation

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Adding value to agro-industrial residues is becoming increasingly important, satisfying needs to promote resources’ use efficiency and a more sustainable and circular economy. This work performs a parametric and kinetic study of enzymatic esterification of lard and tallow with high acidity, obtained by the rendering of slaughter by-products, allowing their use as a feed ingredient and increasing their market value. After an initial analysis of potential enzyme candidates, a Candida antarctica lipase B was selected as a biocatalyst for converting free fatty acids (FFA) to esters, using excess ethanol as the reagent. Results show that the fat acidity can be reduced by at least 67% in up to 3 h of reaction time at 45 °C, using the mass ratios of 3.25 ethanol/FFA and 0.0060 enzyme/fat. Kinetic modelling shows an irreversible second-order rate law, function of FFA, and ethanol concentration better fitting the experimental results. Activation energy is 54.7 kJ/mol and pre-exponential factor is 4.6 × 106 L mol−1 min−1. Full article
