Innovia Films have established sound environmental credentials for their products and processes by using Life Cycle Assessment and Scenario Modelling-tools in the GaBi Software. Andrew Sweetman, Business Development and Sustainability Manager at Innovia Films describes the benefits thus “When we are looking towards possible process changes, our department is now being consulted to see if there might be any impacts, positive or negative, associated with these changes. So it´s helping to lead our investment programme and make sure that, if we do plan to change anything, we understand the impacts and make an informed choice between different options, before we commit the capital investment.”
Modeling Tip: Importing & Exporting Traffic Data in CALRoads View
The CALINE series of models was developed to estimate pollutant concentrations from motor vehicles at roadway intersections. It includes three primary models: CALINE, CAL3QHC, and CAL3QHCR. The latter allows processing of real meteorological data (up to one year) and input of vehicular emissions, traffic volume, and signalization (ETS) data. Data reflecting traffic conditions for individual hours of a week can be input into CAL3QHCR. Lakes Environmental recently released CALRoads View Version 6.5 which includes...
Study shows online consumers want environmentally friendly options
Reducing the carbon footprint of what we buy isn’t easy, but the opportunity for impact is substantial: In the United States, producing and delivering consumer purchases releases twice as much carbon into the atmosphere as home energy use and personal travel. By gathering and sharing information on carbon emissions associated with their products, companies can make environmentally friendly choices easier for consumers and boost their own reputations as planet-friendly businesses. Advances in online technolog...
Studies on competitive adsorption of dyes onto carbon (XC-72) and regeneration of adsorbent
Carbon as an adsorbent has been widely studied for wastewater treatment, but the regeneration of adsorbent has been scarcely reported. In this paper, an economical and environmental method was applied to regenerate carbon (XC-72). Results showed that both anhydrous ethanol and deionized water did not obtain optimal effect for the desorption of Acid Orange 7, Ponceau 2R and Rhodamine B, but the desorption effect was dramatically improved when anhydrous ethanol and deionized water were mixed in a certain volume...
Beliefs, Politics, and Environmental Policy
IntroductionMany of us who work on environmental issues have faced the challenge of conveying their importance to nonspecialists. Perhaps we have found ourselves defending the robustness of climate science to a contrarian uncle, or extolling the importance of biodiversity to a dubious aunt. Our relations and friends are often educated people, skilled in their own professions, who have formed strong opinions about the science underlying environmental problems, their potential consequences for their own lives, and...
Intrinsic kinetics for fixed bed bioreactor in hospital wastewater treatment
Variation in hospital wastewater (HWW) pollutants and differences with municipal wastewater (MWW), make the use of biokinetic coefficients obtained from activated sludge in the MWW treatment unprofitable for designing, modeling and evaluation of biological processes for HWW treatment. Since this study was conducted to evaluate the performance and biokinetic coefficients of a fixed bed bioreactor (FBBR) using rice husks as fixed media in HWW treatment, a new modified method was also proposed for biokinetic estimatio...
