  • Tax Credit Tips For Biogas Projects

    With the end of 2016 in plain view, anaerobic digestion (AD) projects in the development phase should examine what has to happen by December 31 in order to tap into available federal tax credits. Under current law, Section 45 of the federal tax code makes AD projects eligible for a Production Tax Credit (PTC), which can be converted into an Investment Tax Credit (ITC), if the projects are used to ...

  • Why Your Project Should Include Articulated Concrete Blocks

    During any construction project, large or small, planning for potential construction erosion is essential. Failing to take into consideration the possibility of erosion when planning a construction site will not only reduce the quality of the soil at the site, but it may also damage surrounding properties, harm the local environment and result in hefty fines and liability costs. To avoid the ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Porirua New Zealand – WaStop® DN225 - Case Study

    Porirua City located 20 km north of Wellington has over 70 storm water outlets into the harbour. A number of these outlets are very flat on their approach to the harbour which generally means they are severely influenced by high tides. The problem with these outlets is that if a rain fall event coincides with a high tide, the ability of the storm water network to discharge is severely restricted. ...

  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Environmental impact of higher recycled content in construction projects

    Construction clients, policy bodies and planning authorities are increasingly setting requirements for projects to measure and increase reused and recycled content. They are asking project teams to adopt the most significant opportunities for cost-neutral good practice within the chosen design, by identifying the top 5-10 substitutions specific to the project where one product can be replaced by ...

  • Construction activities and environmental issues in and around Gaborone City

    Being one of the fastest growing cities in sub-Saharan Africa, Gaborone City, Botswana, is experiencing much construction activity. However, evidence from a study whose findings are reported in this paper, shows that the construction activities have had a negative impact on the environment in and around the city. A few cases have been presented in the paper to raise awareness regarding the issue. ...

  • Conditional constructions: environmental discourses on natural ventilation

    The critical potential of the concept of sustainability may depend on its ability to provide a space for a meaningful dialogue about the possible appropriate relationships between technology, nature and society. However, the contemporary interpretation of sustainable building reflects a process in which a global, consensual and technocratic vision of environmental change has tended to dominate ...

  • Construction Sector - practicing environment

    This article approaches the norms in constructions activities from the environmental perspective. It is solely based on the author's close proximity with the construction activities in terms of site audits, EMS ISO14001 assistance and on-site trainings rendered since 2003. This discussion represents environmental repercussion and effects incurred by many construction companies. These issues are, ...

  • Water cleaning and wetland construction

    Slippery Rock University's Macoskey Center for Sustainable Systems has served as an ideal locale for the study of biological waste and wastewater concerns in Western Pennsylvania. The Center's constructed ponds, waterless composting toilet and indoor greywater treatment system produced, in 19982000, great amounts of data on ecological approaches to wastewater treatment, which need to be reviewed. ...

  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Economic, environmental and socio-cultural sustainability of three constructed wetlands in Thailand

    Constructed wetlands (CWs) for wastewater treatment may be part of the answer to the urgent need for a change in the approach to wastewater treatment in developing countries. Although Thailand has several CWs, there have been no studies of their sustainability. To remedy this, the sustainability of three promising CWs in very different settings was assessed. These were located at Koh Phi Phi, a ...

  • Effects of environmental conditions on the phosphorus distribution of constructed duckweed (Lemna minor) microcosm

    The restoration of eutrophicated lakes using duckweed plants (Lemna minor) is recognised as a potentially low-cost method. In this study, the effects of environmental conditions on phosphorus (P) distribution were investigated in constructed duckweed microcosms by means of 32P isotope labelling; 32P activities in microcosms were monitored to determine P distribution activities. Results indicated ...

  • Cumulative Environmental Impact Of Cascade Hydropower Dams Construction On The Water-River

    Abstract Variation of environmental indices in cascade dams could be intensified in comparison with single dams. In cascade dams the intensification of long term negative impacts are more important than the impacts in single case dam. In addition, these impacts are more permanent and intense, so the precise study of cascade dams is indispensable. The main goal in this research is to study the ...
