Research for new solutions in the field of wood-based materials and possibilities of their refinement is prompted by both market needs and increasingly restrictive environmental regulations. Many opportunities in this area are created by modern industrial technologies and constantly improved varnishing products as well. The observed trend indicating the usage of increasingly advanced technologies for the refining of wood-based materials in plants producing these composites confirms such activities and it creates new market opportunities. The correlations between the consumption of varnishing materials and the VOC index depending on the application technology were established. The economic and environmental benefits of the refining process concerning wood-based materials in their production plants were shown for both the manufacturers of the refinished composites and their buyers.

On-site detention (OSD) of storm runoff decreases catchment peak flows through the routing effect of temporary storage; on-site retention (OSR) achieves the same objective by abstracting part of the urban flood wave and passing the retained water to disposal on site. The investigation explored both strategies applied to a set of hypothetical present/re-developed urban catchments ranging in size from 14 ha to 210 ha. Comparisons were made on the basis of site storage required (SSR) to achieve the same global peak flow reductions, environmental aspects and cost. OSR practice was shown to out-perform OSD generally in medium-large catchments with respect to SSR and, hence, cost. The retention option also has clear environmental benefits that fall beyond the scope normally ascribed to OSD practice. The paper cautions against use of OSR in unsuitable circumstances.

AbstractWaste management strategies such as anaerobic digestion and composting produce bio-based fertilizer products that could be applied to agricultural soil. Although multiple modelling software tools are available to simulate the environmental effect of fertilizer application to the soil, these models do not allow specification of emerging bio-based fertilizer types. Moreover, mathematical process models exist that allow optimizing the operational settings of waste management processes in order to produce an optimal bio-fertilizer quality adjusted to the local market needs. If an integrated tool would be available that couples process modelling to watershed modelling, the valorization chain could be simulated as a whole, i.e. the bio-fertilizer type and composition could be adjusted to the local watershed and environmental impacts of bio-based fertilizer production and application could more easily be assessed and controlled. The availability of such integrated tool may as such allow for improved decision and policy making regarding bio-fertilizer production and application with environmental benefits as a result.

Sustainable Food

Local seasonal food choices are environmentally relevant behaviors and a promising opportunity for enhancing sustainable food consumption. Therefore, we need a more integrated understanding of motives driving consumers to opt for food that is produced locally and also in its natural growing season. The aim of this study is to (i) identify which motives for local food choices are also relevant for local seasonal food choices and (ii) investigate whether environmental motives become (more) relevant for these environmentally friendly choices. To assess consumer perceptions of socioeconomic, health, and environmental aspects, a survey in combination with a choice-based conjoint experiment to measure consumer preferences for seasonal (apples) and non-seasonal choices (tomatoes) was conducted. The data were collected by means of an online-panel survey (n = 499) and analyzed using two structural equation models. Results revealed that while the support of the local economy presents the most relevant driver, consumers’ price sensibility is even more relevant as a barrier. What differs is the relevance of authenticity and local identity. While local seasonal food provides environmental benefits to consumers, these benefits have no implications for the relevance of environmental motives. Based on these findings, we derive evidence-based recommendations for policymakers and marketers and propositions for future research regarding additional drivers and barriers for local seasonal food consumption.

In the last few years, the automotive industry has been moving towards fuel-free and economically sustainable alternatives, motivated by the latest trends in the market and new regulations about CO2 emissions. Hybrid and electric vehicles feature a transmission drive with one or more electrical motors powered by Lithium batteries. Thus, Lithium batteries are increasingly used in onboard energy storage systems, leading new economical, technical and environmental challenges which are of fundamental importance in this early stage for the next automotive generation. Recycling materials from used Lithium batteries can also moderate the price of virgin materials, by reducing the price disposal as well as the dependence of manufacturers on exporting countries. Furthermore, recycling Lithium-ion batteries has significant environmental benefits, such as containing the risk of chemical pollution and improving safety in storage facilities for exhausted batteries worldwide. This paper aims to provide a comprehensive insight on Lithium-ion battery recycling for scientific research and industrial applications, examining the economic, technical and environmental aspects of this topic.

Abstract For high utility value of products is significant quality of surface treatment. Among the processes that most affect the quality of surface treatment are mainly surface pretreatment processes, namely processes of cleaning (degreasing). This article is devoted to quality control after surface pre-treatment. It mainly deals with the modern method for detecting surface contamination grease based on fluorescence methods. Impurities such as grease, oil and other have characteristic fluorescence after illumination by UV source. This principle can be used to determine the purity of the substrate surface, thereby ensuring the quality of the surface. Surface cleanliness is very important factor for the correct application of subsequent technological processes.

It was determined that the handling of the solid waste generated by the SOLCA – Chimborazo cancer hospital was not appropriate, both internally and externally. Because of that, the classification, transport, storage, deactivation, and intermediate disposition are inconvenient. Thus, it was realized that it is important to have the requirements and documents to follow and comply the objectives that are specified within the management, focusing on feedback and continuous improvement. To learn about the nature of the generated residuals, they were characterized in the hospital. Common, infectious, radioactive, organic and sharp residuals were found during the months of September, November and December. The common waste is comprised of cardboard, paper and plastic. The per-capita production of residuals was 0.76 kg/patient/day. The environmental impact caused by the generation of hospital solid waste was 56% severe impacts and 44% moderate impacts, which could elicit health problems in the population surrounding the hospital. For this reason, the appropriate management of solid waste allowed to obtain large environmental benefits and reduce the pollution generated by the hospital solid waste. It is recommended to SOLCA-Chimborazo and other health institutions the implementation of an adequate solid waste management, which will allow them to comply with all the requirements enforced by the environmental regulations.
