  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • Why ‘custom-built’ is often cheaper than off the shelf

    We know that we’ve said it before, but even though we list what we call our ‘standard range’, by far and away most of the incinerators and cremators we manufacture are specially designed and manufactured to match the individual needs of each customer.  Since everyone’s requirements are different, virtually every unit we produce is ‘made to order’ and the ...

  • 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 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. ...

  • 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 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, ...

  • Vertical Flow Constructed Wetlands

    The constructed wetland technology is today continuously evolving with new and innovative applications. Vertical flow constructed wetlands is a relatively new and still developing technology in the field of ecological and environmental engineering. These ecological systems offers us the potential to treat water and sludge in a more sustainable way, even when financial sources are limited. The ...

  • Construction Waste Recycling

    Construction Waste Recycling,Construction Waste Plant | Machine Construction waste recycling and demolition materials produced at a construction location are increasingly significant. The environmental advantage of recycling can be considerable. A great deal of this energy savings result from reduced utilization of natural ...


  • 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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Kirk Environmental constructs Biffa`s `super AD facility` case study

    Contracting for Biffa, Kirk Environmental constructed the UK's largest anaerobic digestion plant capable of processing up to 120,000 tonnes of food waste every year. The plant will produce enough energy to power up to 6,000 homes which will be diverted to the national grid. Kirk Environmental constructed the 5 4800m² Glass Coated Steel Digestion Tanks complete with Stainless Steel Roofs. ...

  • Management systems for sustainable construction: integrating environmental, quality and safety management systems

    The management systems implemented by contractors are paramount to encouraging sustainable construction. Evolving from developments in the manufacturing industries, a number of forward-looking contracting organisations are at the forefront of establishing Integrated Management Systems (IMS) within the UK. IMS can provide a framework for sustainable construction through the effective management of ...

  • 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 ...

  • Construction of a low–cost laser–based multiplexed spectrometer: a potential probe for environmental pollution monitoring

    A low–cost, sensitive, laser–based (Helium Neon; He–Ne) optical Fourier–transformed (multiplexed) spectrometer has been constructed for the quantification of suspended particulates in the air. The optomechanical features of the spectrometer are presented together with a theoretical framework of its operation. The apparatus is calibrated by using a standard commercial spectrophotometer and has ...

  • Influence of design, physico-chemical and environmental parameters on pharmaceuticals and fragrances removal by constructed wetlands

    The ability of several mesocosm-scale and full-scale constructed wetlands (CWs) to remove pharmaceuticals and personal care products (PPCPs) from urban wastewater was assessed. The results of three previous works were considered as a whole to find common patterns in PPCP removal. The experiment took place outdoors under winter and summer conditions. The mesocosm-scale CWs differed in some design ...

  • Environmental impact of irrigation with greywater treated by recirculating vertical flow constructed wetlands in two climatic regions

    Reuse of greywater (GW) has raised environmental and public health concerns. Specifically, these concerns relate to onsite treatment operated by non-professionals; systems must therefore be reliable, simple to use and also economically feasible if they are to be widely used. The aims of this study were to: (a) investigate GW treatment efficiency using 20 full-scale recirculating vertical flow ...
