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.”
Horizon and water treatment
Horizon is an environment company focused on water treatment.In the latest years,with the improvement of industrial economy,water quality is becoming worse and worse.To prevent the pollution trend,our government has raised the standard of sewage discharge several times,so traditional process and technology of water treatment can’t apply for the environmental requirements and technology revolution and innovation are necessary.In the recent years,many company and community have improved products to meet...
Santa Cruz Meets THM/DBP Challenge with Unique Air Stripping Process - Case Study
SummarySanta Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. The City evaluated various aeration treatment processes and chose an E-Z Tray® Air Stripper from QED as the best fit for meeting their water quality and O&M goals. The EZ Tray air stripper...
Numerical routing of tracer concentrations in rivers with stagnant zones
Modeling pollution transmission in rivers is an important subject in environmental engineering studies. Numerical approaches to modeling pollution transmission in rivers are useful tools for managing the water quality. The advection-dispersion equation is the governing equation in the transport of pollution in rivers. Recently, due to advances in fractional calculus in engineering modeling, the simulation of pollution transmission in rivers has been improved using the fractional derivative approach. In this...
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...
