Environmental pollution is one of the major concerns throughout the world. The rise of industrialization has increased the generation of waste materials, causing environmental degradation and threat to the health of living beings. To overcome this problem and effectively handle waste materials, proper management skills are required. Waste as a whole is not only waste, but it also holds various valuable materials that can be used again. Such useful materials or elements need to be segregated and recovered using sustainable recovery methods. Agricultural waste, industrial waste, and household waste have the potential to generate different value-added products. More specifically, the industrial waste like fly ash, gypsum waste, and red mud can be used for the recovery of alumina, silica, and zeolites. While agricultural waste like rice husks, sugarcane bagasse, and coconut shells can be used for recovery of silica, calcium, and carbon materials. In addition, domestic waste like incense stick ash and eggshell waste that is rich in calcium can be used for the recovery of calcium-related products. In agricultural, industrial, and domestic sectors, several raw materials are used; therefore, it is of high economic interest to recover valuable minerals and to process them and convert them into merchandisable products. This will not only decrease environmental pollution, it will also provide an environmentally friendly and cost-effective approach for materials synthesis. These value-added materials can be used for medicine, cosmetics, electronics, catalysis, and environmental cleanup.

The preliminary results of utilization of fly and bottom ash from combustion of biomass for the produce of cement mortars has been presented. Currently, this waste are deposited in industrial waste landfills. The chemical composition of waste materials was determined using X-ray fluorescence (spectrometer ARL Advant 'XP). ). In the studies sand was replaced by mix of fly and bottom ash from the combustion of biomass in an amount of 10-30% by weight of cement CEM I 42.5 R (Cemex). The obtained cement mortar concrete were subjected to microscopic examination (LEO Electron Microscopy Ltd.) and their compressive strength (PN-EN-196-1), frost resistance (PN-EN 1015-11 and PN-B -04500 ) and absorbability (PN-85/B-04500) were identified. The obtained results showed, the replacement of the cement by mix ashes from combustion of biomass reduce consumption of raw materials and will have a good influence on the environment.

Industrial Waste Heat

The domestic industrial sector uses over 32 quads of energy that represents one-third of the total energy consumed annually in United States of America. Energy consumption details can be found at www.eia.doe.gov/aer/. Obviously, that the efficient use of available energy has a substantial impact on the competitiveness of domestic manufacturers as well as on the environment. Efficient conversion of raw materials into usable products and usable work/energy strictly depends on the commercially available technologies and equipment. Energy efficiency significantly varies across multiple industries and different applications but one of the major energy losses is thermal energy loss, so-called waste heat. Sources of the waste heat comprise of variety of gaseous exhausts, waste process liquids, cooling media, chemical waste and environmental losses. Over 30 years the engineering community has been trying to develop cost-effective approaches for waste heat recovery and utilization. However, so far there is no universal and cost-effective solution or approach for the industrial waste heat recovery and utilization. In this paper authors discuss an integrated strategy of the industrial waste heat use through the consideration of the closest surrounding of the waste heat source and other types of waste (chemical, mechanical, acoustical, etc.) along with most promising heat exchanger design concepts to be appropriate for integrated waste heat recovery and utilization.

High Cellulose

Various result of agricultural waste that contain high cellulose can be used as an alternative adsorbent. One of them was derived from dried corn stalks which traditionally burnt after harvest that lead to environmental pollution. It is necessary to produce the value-added materials from corn stalks waste as an alternative adsorbent to reduce the level of chlorine in treated water. This process was performed by using various level of sulfuric acid concentration 1%, 3% and 5%, particles size 50 and 70 mesh in 105 oC with adsorbtion time 30, 60 and 90 minutes. The most favorable activation result was obtained at 5% concentration, with particle size 70 mesh, adsorbtion time 90 minutes and the iodine value was 482 mg/l with level of adsorbed chlorine was 96,08%. Based on this findings, we concluded that the corn stalks waste can be used as an alternative adsorbent in reducing the level of chlorine in treated water.

Abstract Purpose This study aimed in exploitation of lignocellulosic wastes for the evaluation of the newly isolated white-rot fungal strains enzymatic potential, covered by the circular economy frame.Methods A standard microbiological methods for the isolation of the white-rot fungal mycelia were used, followed by DNA extraction, PCR amplification, and the API ZYM test. The determination of laccase activity was based on the oxidation of guaiacol while the DNS method was used for the hydrolase determination.Results The isolates, belonged to Basidiomycetes, Fomes fomentraius TMF2, Schizophyllum commune TMF3, and Bjerkandera adusta TMF1, could synthesize extracellular laccase and various hydrolase while growing on lignocellulosic waste materials. More specifically, for the first time, F. fomentarius TMF2 synthesized laccase using sunflower meal as a substrate. This substrate could stimulate B. adusta TMF1 for Carboxymethyl cellulase and Avicelase production. The strain TMF1 was able to produce amylase during its growth on brewerʼs spent grain, which is up to now the best result reported for this activity of any B. adusta strain. Soybean meal was the most potent substrate for stimulating pectinase production by TMF1 and S. commune TMF3. While growing on brewerʼs spent grain, TMF1 and TMF3 strains produced high levels of xylanase. Spent coffee residues were for the first time tested as a substrate for hydrolase production by selected fungal species.Conclusion The obtained results showed that newly isolates of white-rot fungi can grow on unexploited lignocellulosic waste materials to produce different enzymes as a value-added products suitable for various biotechnological applications.

Agricultural waste is environmental problem in Amphawa district. Therefore, Biochar is the alternative choice of waste minimization from agricultural waste. This research was aimed to produce biochar by pyrolysis method and characterize the biochar obtained under different raw materials. Branches of pomelo trees, lychee trees, coconut shells and pomelo pulps and the aquatic weed were used raw material for biochar production. The bio char had high carbon at above 70% w/w all of samples. Potassium concentration of pomelo branches and water hyacinth was 1.85 and 1.048 mg/kg, respectively. Surface area of biochar product from Branch of lychee tree was highest at 253 m2/g.The ratio of 1:1 bio char with organic fertilizers is highest plant growth rate.
