AbstractWith the development of industrialization, the emission of volatile organic compounds (VOCs) to atmosphere causes serious environmental problems and the treatment of VOCs needs to consume a lot of energy. Moreover, indoor VOCs are seriously harmful to human health. Thus, there is an urgent requirement for the development of indoor VOCs treatment technologies. Catalytic degradation of VOCs, as a low energy consumption, high efficiency, and easy to achieve manner, has been widely studied in related fields. As a kind of transition metal catalyst, manganese-based catalysts have attracted a lot of attention in the catalytic degradation of VOCs because of their unique advantages including high efficiency, low cost, and excellent stability. This paper reviews the state-of-the-art progress of manganese-based catalysts for VOCs catalytic degradation. We introduce the thermocatalytic, photocatalytic and photo-thermocatalytic degradation of VOCs on manganese-based catalysts in this paper. The optimization of manganese-based catalysts by means of structural design, decorating modification and defect engineering is discussed. Graphical Abstract

With the development of printing technology, greater emphasis has been laid on environmentally friendly materials. Due to its printability and environmental friendliness, Water-based flexo ink is gradually gaining popularity at home and abroad, and has been widely applied in the field of printing. Different from other kinds of bills, scratch-type invoices have an additional scratch area on the surface, which highly covering performance is required for the ink applied. This paper emphatically analyzes and discusses: (a) flexo water-based covering ink and its application in scratch-type invoice covering region printing; (b) how to explore and evaluate new developed green inks. Compared with traditional inks, the water-based flexo ink is free of emissions of volatile organic compounds (VOC), and its popularization might have significant meanings for the environment protection and sustainable development.

This research is a study and development of environmentally friendly products from rice stumps for community economy. The study was done by testing the coatings for heavy metals and volatile organic compounds to match with material choices with low environmental impacts. The author therefore chose 9 types of popular coatings which the community can easily obtain from the market. Testing was done in two parts: the first part was to find 7 heavy metals by using Thailand’s green label standard and standard criteria set by the European Union while the second part was to test for volatile organic compounds (VOCs) and evaluate the environmental impacts in order to list materials and energy used by the products for their entire lifetime. Lastly, a survey was conducted using environmentally friendly products from rice stumps as models in order to investigate the perceptions in relation to manufacturing factors consistent with the manufacturers, the designers, as well as the perceptions of consumers. The study has found that rice stump coatings that passed the standard criteria are white shellac, gloss lacquer, wood preservatives, varnish and polyurethane respectively. It was found that manufacturers and designers had differing opinions in using low-impact materials and avoiding harmful materials while manufacturers, designers and consumers had statistically significant differing opinions in terms of the appropriate sizes and colors of products. In terms of product aesthetics, convenience of use, promotion of environmental friendliness, indication of natural manufacturing process and ease of elimination after the end of product lifetime, there were no differing opinions which were at a good level.

AbstractAn experimental and mechanistic study on the destruction of Volatile Organic Compounds (VOCs: Methane, Methyl Chloride, Chlorobenzene, Toluene, Methyl Ethyl Ketone, 1-Pentene and Cyclohexene) in 0.21: 0.79 oxygen-nitrogen mixture “zero air” over the concentration range of 5-100000 ppm by dielectric barrier corona discharge plasma was performed. Tubular-flow, coaxial-wire, AC-powered dielectric barrier corona discharge reactors were used to determine the kinetics of destruction, reaction products and electric power requirements. High efficiency VOC destruction/removal was demonstrated. Efficiency of destruction (calculated per unit volume of air) increases with decreasing VOC concentration. At low VOC concentrations (5-100 ppm) the energy required for destruction is 0.001- 0.1 J cm
