  • LGD F200 - Designed for easy zeroing and span adjustments

    Regular zeroing and span adjustments to gas analyzers in the field are suggested and required for a variety of reasons. Compliance to environmental standards, e.g. those outlined in the US EPA (40 CFR) or EN 14181 is an important factor. Special application conditions, e.g. a varying gas matrix or compensating for pressure effects can be additional reasons, where a zeroing and span adjustment ...

  • Zero Waste - Zero Waste - Zero Waste

    The Planning Group of the Zero waste International Alliance defines zero waste as: “Zero waste is a goal that is ethical, economical, efficient and visionary, to guide people in changing their lifestyles and practices to emulate sustainable natural cycles, where all discarded materials are designed to become resources for other use.” I recently posted this question on ...

  • Welcome to Net-Zero

    For most people (and for most homes) the likelihood of going through a whole year spending next to nothing on energy is a goal that seems far out of reach. In fact, it is only relatively recently that insulation technologies, coupled with cutting-edge renewable energy tools, have made the concept of a net-zero energy use home anything more than a pipe dream. However, thanks to a program at the ...

  • Winning With Zero Waste

    In the business of professional and collegiate sports, with top priority on championships, player injuries, and filling stadium seats, attending a meeting with Martin Tull, Executive Director of the Green Sports Alliance (Alliance), seems like a walk in the ballpark. “When we speak to potential members, we often say, ‘Would you like to know how other teams are saving millions of ...

  • Zero Waste System in Paradise

    Most visitors to Fiji come for rest and relaxation on the white sand beaches or for diving and snorkeling among the unspoiled coral reefs. Few visitors realize that this tropical island in the South Pacific, north of New Zealand, is on the cutting edge of industrial ecology with a fully functional, zero waste program located near the Fijian capital of Suva. As part of an EPA funded review of ...

  • How to reach zero net greenhouse gas emissions in three steps

    Can the world’s nations afford to make the changes needed to reach net zero greenhouse gas emissions and avoid catastrophic climate change? Yes, says the World Bank Group — if we start now and incorporate three important components into our strategy. In a new report, ...

  • Net Zero Waste – So What?

    Leading world organizations warn us that economic growth and social development cannot be sustained with our current consumption, production and disposal patterns. Yet in spite of increasing sustainability initiatives and better product and recovery technologies, global waste continues to grow at an alarming rate. According to ISWA (International Solid Waste Association) global communities ...

  • Denmark’s Near-Zero-Waste Wonder

    Has this Danish community found the formula for environmentally friendly industry? When we look closely at systems in nature — coral reefs or rainforests, for instance — we see something we don’t often see in human systems: mutually beneficial relationships and energy flows among the various elements, such as air, water, rocks, soil, and plant and animal life. If we ...

  • Zero emissions day: What it is and why we need it

    Today is September the 21st – a day that didn’t hold any particular significance until a simple observation occurred in the 1980’s. Ken Wallace, father of a newborn daughter, realized, after witnessing the local neighborhood pizzeria truck, parked, running and driverless, combined with the surrounding traffic that “Stopping all this for a bit would be most excellent for ...

  • Pilot-scale demonstration of the hybrid zero-valent iron process for treating flue-gas-desulfurization wastewater: Part I

    The hybrid zero-valent-iron (hZVI) process is a novel chemical treatment process that has shown great potential in previous laboratory and field bench-top scale tests for removing selenium, mercury and nutrients from various industrial wastewaters. In this study, a pilot-scale demonstration was conducted to continuously treat 3.8–7.6 L/min (1–2 gpm) of the flue-gas-desulfurization ...

  • Zero Waste to Landfill Goal: Portland Aluminium

     Portland Aluminium has achieved a significant reduction in the amount of waste going to landfill. Although driven primarily by business needs including the pursuit of efficiencies, waste reduction has been achieved by evaluating processes, gaining the commitment of its workforce and combining these efforts with both cleaner production and waste minimisation concepts. ...


  • Feeding yourself - The concept of a zero-emissions home

    The discipline of Ecological Engineering is an emerging field mimicking ecological processes, within natural or constructed imitations of natural systems to achieve engineering goals. Applying ecological engineering to a future, carbon intensive environment considers the transport of nutrients and energy within our local micro-systems to integrate and maximise eco-efficiencies. Zero emission ...

  • Old Tires Face the Zero Waste Option

    TIRE PILES and tire fires were a prominent environmental burden 20 years ago, but today's options are cleaner with better economic payback. Recovery and use of rubber as an industrial material are far more valuable than use of these feedstocks as fuel. While the price of energy may have doubled in the past few years, the price of virgin rubber compounds has more than tripled - from 30 cents to 95 ...

  • 3 Steps to Decarbonizing Development for a Zero-Carbon Future

    A new World Bank Group report lays out three steps countries can follow to reduce net emissions of greenhouse gases to zero and stabilize climate change: Plan for the end goal, not just the short-term; get prices right as part of a broad policy package that triggers changes in investment and behavior; and smooth the transition for those most affected. The actions ...

  • Pilot-scale demonstration of the hybrid zero-valent iron process for treating flue-gas-desulfurization wastewater: Part II

    The hybrid zero-valent-iron (hZVI) process is a novel chemical treatment process that has shown promise for removing heavy metals and nutrients from industrial wastewaters. In this study, a pilot-scale demonstration was conducted to continuously treat 3.8–7.6 L/min (1–2 gpm) of the flue-gas-desulfurization (FGD) wastewater at a coal-fired power plant for 5 months. In this paper, a ...

  • Exergy analysis of natural gas/DME combustion in homogeneous charge compression ignition engines (HCCI) using zero–dimensional model with detailed chemical kinetics mechanism

    In the present work, a single zone combustion model with detailed chemical kinetics is developed to study the effect of dimethyl ether (DME) concentration on the combustion of natural gas from second law point of view in a homogeneous charge compression ignition (HCCI) engine. The code can predict all exergy terms in the cylinder with crank angle during a closed cycle. The chemical kinetics ...
