The pulp industry faces challenges in balancing biological wastewater treatment with effective odor control.

   SciCorp’s micronutrient technology, based on plant extracts, selectively stimulates specific bacteria within biological sludge to significantly reduce emissions of malodorous gases such as hydrogen sulfide and mercaptans. Additionally, this technology enhances the biological treatment performance by increasing load capacity, lowering phosphorus concentration in the treated effluent, and reducing biosolid production, thereby optimizing overall wastewater treatment plant efficiency.

   A hybrid material of activated carbon and MOFs is proposed for the adsorption of trimethylamine (TMA) emitted by the fishing industry, achieving complete removal in the aqueous phase.

   Efforts focus on optimizing its surface area and selectivity for effective application under real conditions, contributing to environmental impact mitigation and improving the quality of life of nearby communities.

   Increasing citizen demands for better environmental quality have led Chile, a party to the Escazu Agreement, to adopt participatory monitoring in environmental assessments, including for odour pollution.

   This work aims to compare the D-NOSES citizen-based odour data collection method with traditional assessment approaches. The study will evaluate the consistency of citizen-reported odour observations using an odour annoyance index. This assessment is crucial to validate the reliability of citizen-generated odour measurements.
