The authors’ concept of environmentally friendly defense against marine biofouling is elaborated. Three ways of its implementation are considered: non-biocidal antiadhesive protection with the use of some metal oxides and organics and also coats with reduced environmental impact due to partial substitution of the DBA antiadhesive component for copper. The basic coat used was KELT-2 developed at S. V. Lebedev Synthetic Rubber Research Institute. The antifouling substances and coats were studied in the laboratory using methods of experimental biology, and the coats were tested in the marine environment using vane-like mobile stands. The results of technical and biological tests of epoxy-rubber coats at the White Sea and the Black Sea demonstrated their high efficiency in comparison with common ship paints. The prospects of further development of ecologically safe antiadhesive coats and copper-based coats with reduced environmental impact are discussed.

The environmental problems accompanying concrete come from cement. This means that the final product i.e., concrete is an environmentally sociable material by itself. This guides us to play on the concrete constituents which cause the largest environmental impact, which is cement. Therefore, if we can abate cement amount and increase cementing materials which can substitute cement for concrete, we will be able to minimize the concrete impact on the environment. The saving of cement quantity in concrete can be realized by substituting it with diverse extra cementitious materials which are a by-product of another industry and waste of agriculture.

Diminishing natural resources have increased the prominence and implementation of approaches to sustainable planning, design, and application. Green schools minimize environmental impact by promoting environmentally friendly attitudes, reducing the need for infrastructure facilities, and using recycling as a strategy both during and after their construction. As with other green buildings, green schools reduce dependency on fossil fuels and thus limit the emission of carbon dioxide and other pollutants. Concerning global warming, green schools have the capacity to “turn back time,” creating learning circles that elicit solutions from their student bodies. In this chapter, the authors explore the economic, ecological, and social dimensions of green schools by means of a case study of an education campus in Adana, Turkey. The authors aim to elucidate how green schools may be effective in the conservation of future resources in architectural sustainability.

Purpose This study aims to contribute to a better understanding of environmentally friendly consumers. It examines differences in holiday transport mode choices by persons’ general level of environmental commitment across lifestyle domains. Adopting a marketing perspective, the study also explores transport mode perceptions and underlying product attribute preferences that may shape holiday transport mode choices. Design/methodology/approach The study adopted Kaiser’s (1998) General Ecological Behaviour scale to measure commitment to environmentally friendly behaviour. ANOVAs were run to examine differences in actual holiday travel behaviour and transport mode perceptions by level of environmental commitment. Pattern models were calculated to estimate differences in the relative importance of selected transport mode attributes (price, travel time, punctuality, accessibility, flexibility, comfort and environmental impact). Findings The study findings suggest that differences exist in transport mode choices for train and car use, but not for plane use, namely, train users tend to be more environmentally committed and car users less so. Differences were also noted in transport mode perceptions, with more environmentally friendly consumers holding more favourable views of the train. Those who are more environmentally committed also placed greater importance on environmental impact and less importance on comfort and time in mode choice. Originality/value The study applied an environmental scale thus far not used within tourism research. It also adopted a marketing perspective focused on product attributes to support the development of strategies to encourage environmentally friendly holiday transport mode choice.

And Performance

Adhesives and sealants (AS) are materials with excellent properties, versatility, and simple curing mechanisms, being widely used in different areas ranging from the construction to the medical sectors. Due to the fast-growing demand for petroleum-based products and the consequent negative environmental impact, there is an increasing need to develop novel and more sustainable sources to obtain raw materials (monomers). This reality is particularly relevant for AS industries, which are generally dependent on non-sustainable fossil raw materials. In this respect, biopolymers, such as cellulose, starch, lignin, or proteins, emerge as important alternatives. Nevertheless, substantial improvements and developments are still required in order to simplify the synthetic routes, as well as to improve the biopolymer stability and performance of these new bio-based AS formulations. This environmentally friendly strategy will hopefully lead to the future partial or even total replacement of non-renewable petroleum-based feedstock. In this brief overview, the general features of typical AS are reviewed and critically discussed regarding their drawbacks and advantages. Moreover, the challenges faced by novel and more ecological alternatives, in particular lignocellulose-based solutions, are highlighted.

Abstract The Aedes aegypti mosquito is a vector of several diseases, such as dengue, malaria and the Zika virus. Synthetic insecticides such as chlorpyrifos and chlorothalonil have been used for plague control, despite causing damage to the environment and to humans. It is therefore important to study natural active compounds with a low environmental impact. The present paper developed an environmentally friendly formulation of silk fibroin (SF) associated with fatty acid esters [ethyl (FAEE-SF), propyl (FAPE-SF) and butyl (FABE-SF)] from Astrocaryum murumuru Mart. fat, which was effective against Aedes aegypti 3th instar larvae. The FABE-SF nanoemulsion induced a higher mortality rate in the larvae of the A. aegypti after 48 h (LC50 = 18.92 µg / mL). The stabilities of the nanoemulsions were monitored for 21 days, and FABE-SF exhibited greater stability throughout the monitored period, with average particle, zeta and PDI values of around 217 ± 0.85 nm, -25.6 ± 3.24 mV and 0.338 ± 0.01, respectively. This paper reported the first effective action of fatty acid esters from A. murumuru Mart. associated with silk fibroin against A. aegypti. The FABE-SF solution also had a low hemolytic index, suggesting that treatment may be safe for animal and human use.

Wood modification (chemical, thermal, impregnation) represents an assortment of innovative processes continually being adopted in the wood protection sector. COST Action FP1407 “Understanding wood modification through an integrated scientific and environmental impact approach — ModWoodLife” was initiated in 2015, with its 4-year programme aiming to investigate modification processing and products design with emphasis on their environmental impacts. Among the final tasks within COST FP1407 was to re-evaluate the current status of wood modification across the member countries. However, it became clear that activities in other European countries needed to be addressed, and as a result, a more extensive evaluation of wood modification processes across Europe was undertaken, as well as determining the activities globally. This paper outlines some of the recent updates in wood modification, along with summarising data collected by the authors from international colleagues and online sources, so providing an evaluation of the overall global position. These figures suggest that wood modification is undergoing a significant increase in production due to demand, with levels of recent growth seemingly suggesting this will continue for the coming years. Based on data gathered, the global commercial production of modified wood is dominated by thermal modification processes, which produce 1,110,000 m3/year. Among the other commercialised processes, acetylation accounts for 120,000 m3/year and furfurylation 45,000 m3/year. A further global production of around 330,000 m3/year is estimated for other processes, predominantly based on resin-based systems (e.g., Impreg- and Compreg-based processes).

The use of composting technologies to treat food waste (FW) now represents an environmentally friendly form of waste treatment, in which organic matter can decompose biologically. However, the damaging emissions of composting technologies for FW treatment vary, thus a life cycle assessment (LCA) approach is often used to certify the quality of the decision-making process. This study quantifies and compares the environmental impact of two scenarios in Malaysia: windrow and hybrid composting (windrow integrated with a landfill) technologies.  The scenario modeling was performed via GaBi v6.0 software using 1 ton of pre-treated FW as a functional unit, with the analysis based on the ReCiPe (H) v1.07 characterization method. The midpoint results revealed that windrow composting technology has a lower environmental impact and is an environmentally friendly option compared to hybrid technology. Treating FW in a windrow scenario has relatively low power requirements for operation with the added advantageous properties of compost production, and a substantial reduction in the distances transferred by the road. The hybrid scenario had the largest negative environmental impact in all categories, such as climate change (1.45E+03 kg CO2 eq), and ozone depletion (4.39E-09kg CFC-11 eq) because of the energy-intensive waste collection and treatment activities it needs, and with no landfill gas filtration. Finally, based on the single score synthesis, windrow is considered as an appropriate treatment with the avoidance of Resource Depletion (6.61E+02 Pt).
