Opis:
The paint waste from the cosmetics packaging industry was sent to the third party for disposal by paying several management fees for hazardous waste. The use of paint waste as raw material for paving block products can reduce the environmental impacts and provide economic benefits. The life cycle assessment is a tool for measuring the environmental impact of this utilization compared to the management carried out by the third party. There are four scenarios reviewed that consist of third-party management, utilization as raw materials for paving block by the concentration of 1, 2, 3, 4 and 5% respectively. The analysis shows that the utilization of dry paint waste as a raw material for a paving block can reduce the impact of global warming and photo oxidant. The compressive strength value of paving blocks increased with the addition of the dry paint waste with the concentration of 1 and 2%, then a slight decrease in proportion occurred with the addition of paint waste concentration up to 5%. The addition of dry paint waste does not affect the water absorption with a range of 2%, meeting the standard for a paving block.

Opis:
Food waste has recently received attention due to its environmental, economic and social impacts. Final processing of food waste encounters a number of technical challenges, arising from weak physical structure of food waste with weak porosity, high content of water, and low carbon-to-nitrogen relation. This study deals with the research of food waste processing in households by using an automatic device. The main objective of the study was to assess the toxicity of the end-product produced by an automatic device. The research included 10 experiments. The input foundation consisted of common food waste generated in household kitchens. Following its processing, the end-product was tested in a pot experiment for the germination capacity and biomass increase in different concentrations. The end-product was mixed with the reference soil in concentrations 5/95, 30/70, 50/50 (tested/reference substrate). The testing included three different plant species, i.e. Sinapis alba L., Hordeum vulgare L. and Cannabis sativa L. The germination capacity of plants and their increase in biomass were evaluated after 21 days. The increase in biomass was monitored by using the Before-After-Control-Impact method. The plants developed much better without the end-product additive to the soil substrate than with its small addition. The best germination capacity in the case of end-product addition was observed in the concentration ratio 30/70 in all plants. In spite of this, the highest increase in biomass was recorded in the concentration ratio 5/95. This might have caused the occurrence of mould in the pots. The test shows that the end-product made of food waste is toxic to plants; therefore, it is not recommended for direct application as a soil amendment.

Opis:
A principle of extended producer’s responsibility in the law of waste management pursues the following aims of the waste management: 1) the maximum decrease in the amount of waste in any type of business and human existence, 2) the immediate reuse of production waste in a manufacturing process, 3) recovery of raw materials from collected waste, 4) application of processes to dispose of waste, 5) orderly waste storage ensuring the least damage to the environment. The overriding objective of this principle is application of legal instruments encouraging producers to undertake activities which will: prevent production of waste, decrease the level of using materials and energy at every stage of a product life cycle and encourage to introduce changes in the phase of a product design and during its manufacture. Broadly speaking, a principle of extended producer’s responsibility is connected with a producer’s financial liability for a product. In a legal structure of the extended producer’s responsibility we deal with preventive liability. This principle completes a principle of incurring costs of waste management.

The results of the study regarding utilization of the waste gypsum formed as a by-product during the production of the magnesium sulphate from dolomite have been presented. The use of this waste have been proposed for the production of granulated multi-component fertilizers containing 25% N; 8% S; 14% CaO and 3.5% MgO. In the process of fertilizer production, the urea which will be bounded with the calcium and magnesium sulphate from the waste in the form of adducts of CaSO4 . 4CO(NH2)2 and MgSO4 . CO(NH2)2 . 3H2O will be the source of nitrogen in the fertilizer. It has been stated on the basis of the laboratory tests that the fertilizer with the assumed composition can be obtained by means of granulation of the raw material pulp, along with the dried and ground product return. The possibility of the production of the fertilizer with good physical properties according to the assumed concept has been confirmed in the pilot scale.

Opis:
Catfish (Pangasius sp.) is a freshwater fish commodity that is processed into filet. The development of the catfish fillet industry has generated a lot of waste. One of the uses is making surimi, but not all surimi produced is of high quality. Surimi is an intermediate product that has undergone a process of washing, pressing, and freezing. Surimi with low quality can be improved as raw material for making edible films. Edible film is a thin layer made of material that is safe for consumption and biodegradable. This research aims to determine the best concentration of glycerol as a plasticizer in the catfish surimi protein edible film and to determine the characteristics of the edible film produced. The method that was used in this research is the experimental method with Completely Randomized Design (CRD) with three treatments and three repeats of addition glycerol plasticizer concentrations are 0.6%, 0.8%, and 1.0%. The parameters observed were thickness, tensile strength, elongation, transparency, and solubility. The resulting data were analyzed using ANOVA and continued with the Duncan test (α = 5%). The results showed that edible film with the addition of 1.0% glycerol plasticizer concentration has the best characteristics based on Japanese Industrial Standard (JIS) and statistic analysis with a thickness of 0.068 mm, tensile strength of 402.02 kgf / cm2, elongation of 33.3%, clarity of 98.06% and transparency of 1.94.

Smart design upcycling of post-production display panels into new creative materials to support the sustainable development of a circular economy in the furniture industry. The economy is currently transforming from a linear economy to a circular economy. This is increasingly supported by policy, legislation, industry, and academia. A circular economy means more efficient management of renewable natural resources, which has implications for businesses’ bioeconomies, as expressed in the sustainable development goals of the United Nations’ 2023 Agenda. Our study contributes to solving a research gap by seeking to answer several questions: How can post-production residues be used to improve a company’s bioeconomy? Can they bring profit to a company while saving natural wood? Is upcycling using the smart design of post-production a helpful solution for material and cost savings in the bioeconomy? The outcome of our study is twofold. From a creative input perspective, we show the creative possibilities of upcycling production residues. For business models, we refine the conceptualisation of a sustainable SME circular bioeconomy through the profit gained from such a product solution. Based on our research, we present conclusions and suggestions for small and medium-sized enterprises, scientists, designers, and technologists to help the furniture industry transition from a linear economy to a sustainable circular economy. This promotes company profitability and growth and helps to save natural wood.

Opis:
There is a growing interest in natural antioxidants due to their potential in improving the quality of food and cosmetic products and their health-promoting properties. Distilled spirits contain high amount of ethanol and may be an alternative to the food-grade solvents, while agricultural by-products contain phenolic substances that may have antioxidant properties. This study was therefore conducted to find out if gin, vodka, and tequila flavored spirit, alcoholic beverages with about 40% ethanol, can extract the phenolic compounds from agricultural by-products, and to determine if the extracts possess the antioxidant activity. Peels of ripe banana (Musa acuminata), ripe mango (Mangifera indica), calamansi (Citrofortunella microcarpa), squash (Cucurbita maxima), ripe pineapple (Ananas comosus), purple yam (Dioscorea alata), and sweet potato (Ipomea batatas) were collected, dried, and ground. The phenolic substances in the plant materials were extracted with alcoholic beverages or 40% ethanol. The total phenolic content (TPC) of the extracts was determined by means of UV-Vis spectroscopy using Folin-Ciocalteau reagent and gallic acid as reference compound. The antioxidant activity of the extracts was evaluated through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. Butylated hydroxyanisole (BHA) served as positive control in the DPPH assay. Non-linear regression was applied to the DPPH assay data to estimate the values of median effective concentration (EC50). All three alcoholic beverages were able to extract the phenolic materials from the plant samples. However, the ability of vodka and gin to extract the phenolic substances was either statistically comparable or better than 40% ethanol. The results of the DPPH scavenging assay showed that the M. indica peel had the strongest activity, while C. microcarpa had the weakest scavenging activity. At 1000-ppm level, the antioxidant activity of the M. indica peel was comparable with that of BHA, regardless of the solvent used for extraction. Therefore, the M. indica peel can be a source of natural antioxidants and potential substitute to synthetic antioxidants. Both gin and vodka can be used as a substitute for food-compatible solvents.

Opis:
Currently, the design of garment styles is weakly supporting the MWD concept. It is kept fixed during all its very changeable manufacturing process, thereby increasing pre- and post-consumer fabric wastes. To improve the situation the final values of construction parameters which influence fabric use efficiency should be determined for every unique production order only in the garment manufacturing process. Four garment styles were tested to see how light changes in their width and length influence fabric use efficiency. Even minimal reduction of these parameters can give noticeable fabric savings. Different values of these parameters create slightly different shapes of pattern pieces, and with it, give a huge number of new possibilities to create more efficient production markers. The authors found a way how to make the garment designing process more efficient, as well as, to create a “virtual bridge” between garment designing and the manufacturing phase. Both improvements could give serious benefits: reduced fabric use and product price, as well as, reduced pre- and post-consumer textile material wastes.

The article presents the results of experiments aimed at the identification of the influence of the share of phenol and amine resins in burnt fuel mixtures from wood waste along the basic parameters of the process of their thermal oxidation in a low- -power boiler. Differences in the composition of combustion gases from the burning of waste from “virgin” wood and plywood manufactured using urea-formaldehyde (UF) and phenol-formaldehyde (PF) glues were observed.
Zbadano wpływ udziału żywic fenolowych i aminowych w spalanych mieszankach odpadów drzewnych na kształtowanie się podstawowych parametrów procesu ich spalania w urządzeniu kotłowym małej mocy. Badania prowadzono na laboratoryjnym stanowisku badawczym składającym się z paleniska retortowego o mocy 50 kW odpowiednio oprzyrządowanego. Ocenę składu gazów spalinowych prowadzono przy pomocy przenośnego analizatora spalin wyposażonego w cele elektrochemiczne. Materiałem badawczym były odpady sklejki wodoodpornej (zaklejanej klejem fenolowym – PF), suchotrwałej (zaklejanej klejem mocznikowym – UF) oraz odpady „czystego” drewna. W trakcie eksperymentu zmieniano ilości dozowanego do paleniska powietrza w zakresie 50–140 m3. Stwierdzono, że spalaniu paliw drzewnych zawierających fenolowe żywice klejowe towarzyszyła wyższa zawartość tlenku węgla i węglowodorów, w porównaniu z paliwami zawierającymi żywice mocznikowe i „czyste” drewno. Zwiększanie ilości dozowanego powietrza przy spalaniu sklejki fenolowej powodowało znaczący spadek emisji tlenku węgla i węglowodorów w porównaniu z paliwami zawierającymi żywice mocznikowe, spalanymi w ten sam sposób. Przy spalaniu sklejki mocznikowej i dozowaniu powietrza z prędkością 140 m3/h stwierdzono około trzy razy wyższą zawartość tlenków azotu w gazach spalinowych w porównaniu z „czystym” drewnem i sklejką fenolową. Dodatek sklejki fenolowej do spalanej sklejki mocznikowej przy dozowaniu powietrza do paleniska z prędkością 140 m3/h spowodował znaczący spadek emisji Nox.
