  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • What`s the Best Air Pollution Control Technology for My Process?

    Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release

    The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester. Methane hydrate, which is also referred to as ...

  • Optimising laboratory environment for successful IVF

    The London Women’s Clinic in Cardiff (LWC Wales) is one of ten clinics within its group which collectively provide expert fertility treatment to families across England and Wales. When it comes to IVF and fertility treatment there is no ‘off-the-shelf’ or ‘one size fits all’ solution and, as such, the medical teams produce a bespoke fertility programme for each and ...

  • What`s cool about air conditioning

    Conservationists often mock Americans for their love affair with the car. But the air conditioner appears to be a growing rival for our affection. Twenty years ago only about one-quarter of US residences had central air conditioning; by 2005 it was up to 62%, according to the United States Census Bureau. ...
