Abstract: For many companies, freshwater is a basic ingredient for their operations, while effluents may lead to pollution of the local hydrological ecosystem. Initially, public pressure has been the most important reason for sustainable business initiatives, but today many companies recognize that failure to manage the freshwater issue raises risks, including damage to the corporate image, threat of increased regulatory control, financial risks caused by pollution, or insufficient freshwater availability for operations. It is therefore interesting to know the specific water requirements of various consumer goods, particularly the water-intensive ones. This paper discusses specialised water reporting instruments such as the ‘water footprint’ calculation method and demonstrates it's usefulness in measuring and monitoring corporate sustainability. The water footprint analysis can highlight how near or far a company is from being sustainable and identify those aspects that have the greatest negative effect on freshwater and entire environment. Also it can highlights further management options and ways that companies address in their use of freshwater as one of the aspects of sustainable business performance, because today, many companies recognise that proactive environmental management contributes to their profitability and competitiveness in green markets.

Abstract: Climate change is regarded as one of the most fundamental threats to sustainable livelihood and global development. There is growing a global concern in linking community-managed forests as potential climate change mitigation projects. This study was conducted to explore the local people’s perception on climate change and the role of community forestry (CF) to combat climate change impacts. Two active community forest user groups (CFUGs) from Kaski and Syangja Districts in Nepal were selected as study sites, and various participatory tools were applied to collect primary data. Although most of the respondents were unaware about the words “Climate Change” in study sites, they were quite familiar with the irregularities in rainfall season and other weather extremities. 60% of the respondents had the idea that, due to increase in precipitation, there is a frequent occurrence of erosion, floods and landslide. Around 85% of the people agreed that community forests help in stabilizing soil, reducing the natural hazards like erosion, landslide. Biogas as an alternative source of cooking energy, and changes in crops and their varieties are the common adaptation measures that local people start practicing in both CFUGs in Nepal.

Abstract: A study to assess the various gases emitted by motorcycles in a metropolitan State, Uyo, in Nigeria was carried out. Two hundred commercial motorcycles the mostly available means of transport were used for the study drawn from seven motorcycle parks. The gases examined were nitrogen dioxide, sulphur dioxide, carbon monoxide, chlorine, hydrogen sulphide and ammonia. The overall collection results per motorcycle parks showed the following gases concentrations: Motor Park –A; NO₂; 12.7ppm, SO₂; 13ppm, CO; 1337ppm, H₂S; 20.2ppm, NH₄; 97ppm, Cl₂; 20.3ppm, HCN; 80ppm. Motorcycle Park B-NO₂; 12.1ppm, SO₂, 11ppm, CO; 1508ppm, H₂S; 20.4ppm, NH₄; 116ppm, Cl₂; 19.6ppm, HCN; 71ppm. Motorcycle: Park-C NO₂; 11.7ppm, SO₂; 8.7ppm, CO; 1084ppm, H₂S; 14.1ppm, NH₄; 48ppm, Cl₂; 18.6ppm, HCN; 65ppm. D: NO₂; 5.1ppm, SO₂; 4.7ppm, CO; 550ppm, H₂S; 18.4ppm, NH₄; 48ppm, Cl₂; 25.9ppm, CO; 550ppm, H₂S; 18.4ppm, NH₄; 48ppm, Cl₂; 25.9ppm, HCN; 101ppm. Motorcycle Park E:NO₂; 5.4ppm, CO; 596ppm, H₂S; 4.9ppm, NH₄; 48ppm, Cl₂; 79ppm, HCN; 101pm. Motor Park F: NO₂; 51ppm, SO₂; 5.4ppm, CO; 596ppm, H₂S; 4.9ppm, NH₄; 48ppm, Cl₂; 7.3ppm, HCN; 40ppm. Motorcycle Park G: NO₂; 11.9ppm, SO₂; 10.5ppm, CO; 1616ppm, H₂S; 18.4ppm, NH₄; 185ppm, Cl₂; 25.9ppm; HCN; 101ppm. The most harmful gas; carbon monoxide was significantly high in all the parks and the general results showed an alarming degree of polluted gases emission.

Abstract: Developed a method of synthesis of layered double hydroxides (LDH) of different composition. The investigations the processes of adsorption of phenols on LDH variable composition. Were designed kinetic parameters the processes of adsorption of phenols.

Abstract: Sugarcane straw ash (SCSA), an agricultural waste of sugar industry with disposal problems, was utilized as a source for the synthesis of zeolitic material. Zeolitic material was synthesized by alkali fusion followed by hydrothermal treatment. The effect of crystallization time was studied and the conditions optimized. The materials were characterized by XRD, XRF, SEM, FT-IR, Brunauer-Emmett-Teller (BET) surface area techniques, particle size analyzer, TG /DSC and nitrogen physisorption. The presence of zeolite NaP1 in adsorbent confirms successful conversion of native SCSA into zeolitic material. The physico-chemical properties of SCSA and zeolitic material were compared. The particle size distribution of zeolitic material was in the range of 0.796 – 399 µm and nitrogen adsorption indicated a surface area around 350 m² g^-1. Zeolitic material from sugarcane straw ash was examined by removal of Crystal violet from aqueous solution.
