“…Valorization of food waste from the residential and commercial sectors is valuable from the viewpoints of both environmental sustainability and circular bioeconomy [24,25]. Using food waste as an animal feed resource, respecting all the legislative restrictions, would complement food and processing residues already used as animal feed [26].…”

Environmental Impact Assessment of a Solar Drying Unit for the Transformation of Food Waste into Animal Feed

et al. 2022

Food waste valorization via its transformation into animal feed is a viable alternative for improving food security and the diversion of organic waste from landfills. The manuscript presents the environmental impact assessment of the construction and operation of a novel solar food waste drying unit on the island of Crete in Greece, which is treating food waste from hotels. Life cycle assessment is utilized for the impact assessment. The results indicate a total carbon footprint of approximately 217.5 kg CO2 eq. per ton of treated food waste. In conclusion, the operation phase is the major contributor to the environmental impacts, due to the utilization of electricity.

“…The energy consumed by the three incinerators per one operating cycle is (800 kW + 450 kW) × 4 h + 450 kW × 0.5 h/cycle = 5225 kWh/cycle (2) If the natural gas price (NGP) is expressed in €/kWh, the cost of natural gas would be (5225 kWh/cycle × NGP €/kWh)/(4600 kg ABP/cycle) = 1.136 × NGP [€/kg ABP]…”

“…The continuous deterioration of the environment and resource scarcity caused by human activities has become prominent during the last decades. This fact has shifted the scientific focus to the development of more sustainable practices through the redesigning of manufacturing techniques, the development of novel waste treatment methods, and the recovery of resources from expired or used products [1,2]. The European Union, through Regulation 2008/98/EC, has set a hierarchy for waste management, with the most preferable solution being prevention of waste production, followed by reuse of products, recycling of materials, recovery of resources, and, as a last choice, disposal [3].…”

Assessing the Economic Viability of an Animal Byproduct Rendering Plant: Case Study of a Slaughterhouse in Greece

et al. 2020

Continuous human population growth has led to increased livestock production and hence large quantities of animal byproducts. One of the oldest and most efficient animal byproducts processing techniques is rendering, which facilitates the recovery of resources in the form of fat and protein flour. The purpose of this study is to provide data for the feasibility of rendering as a treatment method. The case of a Greek slaughterhouse is presented, regarding its animal byproduct treatment process through rendering and incineration. Three different waste management scenarios are compared, with rendering proving to have a lower operational cost (€51.80/ton) compared to incineration (€74.10/ton), and rendering followed by incineration (€72.13/ton). The rendering process is then compared with other established animal byproduct treatment methods like composting and anaerobic digestion through the analytic hierarchy process, in terms of environmental, economic, and technological efficiency, with rendering (having a final score of 72%) proving once again superior compared to composting (with a score of 54%), and anaerobic digestion (with a score of 55%).

Effects of dimethoate, an organophosphate insecticide, on photosynthesis of five selected phytoplankton species

2023

<p>Dimethoate is an organophosphate (OP) insecticide used in agriculture to kill insects. However, information on the effect of the insecticide on non-target organisms like phytoplankton is sparse. When dimethoate enters water ecosystems, it affects the photosynthesis of the phytoplankton cells. The effect of dimethoate on the photosynthesis mechanism of three Chlorophyceaen and two Bacillariophyceaen species was studied measuring oxygen production, chlorophyll fluorescence and xanthophyll pigments. Oxygen evolution rates of the five phytoplankton species decreased with increasing dimethoate concentrations. OJIP fluorescence characteristics in presence of dimethoate was similar to those of DCMU inhibition. DCMU is a PSII inhibitor used as a positive control. Non-photochemical quenching (NPQ) development and the concentration of specific xanthophyll pigments decreased with increasing insecticide concentration, giving another evidence for the target of dimethoate in the selected phytoplankton species. Dark relaxation kinetics did not show a photoinhibition of the cells in presence of dimethoate. Perfekthion, the commercial formulation of dimethoate, inhibited the photosynthesis of the tested phytoplankton species stronger than dimethoate, leading probably to photoinhibition.</p>
