This study applies a qualitative content analysis in four forestry-rich European countries (Austria, Finland, Germany, and Slovenia). The state of online communication of 61 companies and 19 industry associations was qualitatively analyzed in 2014 with a focus on eight core sustainability topics of interest that were identified via an international forest sector stakeholder feedback process. Our results show some great similarities, but also some interesting differences in terms of communication frequency and weight of hot topics across countries. The most frequently communicated area was economic contribution of forests (in Finland and Austria), followed by debate over forest conservation versus production (Germany) and the concept-added value of wood (in Slovenia). With the exception of Slovenia, the role of forests in combating global warming was emphasized more frequently within industry associations than among individual forest industry companies. Characteristically, current content of sustainability communicatio n focuses on supplying factual information. Thus, there is a need for developing more targeted and bidirectional forms of stakeholder communication in the future, emphasizing also more active use of social media channels and empowering organizations to promote interactive communication and collaborative learning.}, subject = {Forest Science}, language = {en} } @article{EttweinRohrerVanzoLangthaleretal., author = {Ettwein, Frederike and Rohrer-Vanzo, Valentina and Langthaler, Georg and Werner, Andrea and Stern, Tobias and Moser, Olivia and Leitner, Raimund and Regenfelder, Katja}, title = {Consumer's perception of high gloss furniture: instrumental gloss measurement versus visual gloss evaluation}, series = {European Journal of Wood and Wood Products}, journal = {European Journal of Wood and Wood Products}, number = {75}, pages = {1009 -- 1016}, abstract = {The overall impression of a glossy surface is an important parameter for consumer's choice of wooden products.

The system is also designed to interact with other energy cells locally, thus, improving the utilization of locally generated energy.

This approach aims at developing tailor-made solutions that meet the different local and regional requirements and the electrical energy demand of the observed energy cells. A unique opportunity is created, as the three countries are at varying levels of regional development in the field of energy communities, and the regional requirements and conditions differ significantly. A comprehensive investigation of the technical and economic viability of the ECs in the three regions is conducted on a simulation level. The technical simulation results show an increased self-consumption of individual users and the overall cell in all of the observed testbeds, while the economic analysis shows economic benefits at varying levels in each of the observed testbeds.

The sand and salts that are thrown onto the fire to suffocate the flames can lead to splashes of molten metal, putting the firefighters and the surroundings at risk. A novel process is described where magnesium fires are brought under control using a simple two-step process. First, coated cellulose flakes, which contain approx. 30\% inorganic salts, are blown onto the fire from a distance of several meters. Due to its low bulk density, the material settles smoothly on the fire and immediately covers the flames for several seconds. Before the hot metal can break through this cover, a fine water spray is applied to the fire. The water spray wets the top layer of the cellulose flakes, which will begin to char from the bottom. The water evaporates from within the cellulose flake layer and withdraws heat. It was observed that no hydrogen is formed and that this technique can safely control fires. It is judged that 90 kg of flakes could safely bring a pile of 75 kg of burning Mg flakes under control. By using a pneumatic conveying unit for the flakes, firefighters can effectively and efficiently cover the flames from a safe distance.

For this purpose, the carcasses of 26 Holstein Friesian bulls that had been fattened on the same private farm were assigned to two experimental groups based on their age at slaughter: a young group (YG) (average age: 17.0 ± 1.0 months old) and an old group (OG) (average age: 22.0 ± 1.0 months old). The percentage of crude protein, panel tenderness score, polyunsaturated fatty acid (PUFA) and saturated fatty acid (SFA) content, the PUFA/SFA ratio and the hypocholesterolemic fatty acid (DFA)/hypercholesterolemic fatty acid (OFA) ratio of the bull carcasses decreased significantly with increasing slaughter age. By contrast, the OFA content of the carcasses significantly increased (p < 0.05) with increasing slaughter age. Advanced slaughter age resulted in lower panel tenderness scores. Additionally, the meat of the bulls in the OG was considered to be less healthy because of the less desirable fatty acid composition and nutritional indices, such as the PUFA/SFA and hypocholesterolemic/hypercholesterolemic ratios, compared to the meat from the bulls in the YG. Furthermore, the intramuscular fat and internal fat contained high percentages of PUFA and SFA and high PUFA/SFA and hypocholesterolemic/hypercholesterolemic ratios.

Tires belong to this class of materials. On top, one of their main constitutents, vulcanized rubber, is as elastomer, which cannot be remolten and hence is particularly challenging to put to a new use. Today, the main end-of-life routes of tires and other rubber products are landfilling, incineration in e.g., cement plants, and grinding to a fine powder, generating huge quantities and indicating a lack of sustainable recycling of this valuable material. True feedstock recycling is not feasible for complex mixtures such as tires, but devulcanization can be done to reactivate the cross-linked polymer for material recycling in novel rubber products. Devulcanization, i.e., the breaking up of sulfur bonds by chemical, thermophysical, or biological means, is a promising route that has been investigated for more than 50 years. This review article presents an update on the state-of-the art in rubber devulcanization. The article addresses established devulcanization technologies and novel processes described in the scientific and patent literatures. On the one hand, tires have become high-tech products, where the simultaneous improvement of wet traction, rolling resistance, and abrasion resistance (the so-called "magic triangle") is hard to achieve. On the other hand, recycling and sustainable end-of-life uses are becoming more and more important. It is expected that the public discussion of environmental impacts of thermoplastics will soon spill over to thermosets and elastomers. Therefore, the industry needs to develop and market solutions proactively. Every year, approximately 40 million tons of tires are discarded. Through the devulcanization of end-of-life tires (ELT), it is possible to produce new raw materials with good mechanical properties and a superior environmental footprint over virgin products.

The most important material thereof is polyhydroxybutyrate (PHB), which can replace the commodity polymer polypropylene (PP) in many applications, yielding a bio-based, biodegradable alternative solution. The advantage from using cyanobacteria to make PHB over the standard fermentation processes, with sugar or other organic (waste) materials as feedstock, is that the sustainability is better (compare first-generation biofuels with the feed vs. fuel debate), with CO2 being the only carbon source and sunlight being the sole energy source. In this review article, the state of the art of cyanobacterial PHB production and its outlook is discussed. Thirty-seven percent of dry cell weight of PHB could be obtained in 2018, which is getting close to up to 78\% of PHB dry cell weight in heterotrophic microorganisms in fermentation reactors. A good potential for cyanobacterial PHB is seen throughout the literature.}, subject = {Bio-based Plastics}, language = {en} } @article{KnappLacknerMarkl, author = {Knapp, Alexander and Lackner, Maximilian and Markl, Erich}, title = {Abrasive pads for sustainable and cost-effective industrial and institutional floor cleaning}, series = {International Journal of Advance Engineering and Research Development}, journal = {International Journal of Advance Engineering and Research Development}, issn = {2348-4470}, pages = {84 -- 86}, abstract = {Industrial and institutional floor cleaning today relies on mechanical action combined with chemicals, which is costly and a burden to the environment.
