EmissionsEmissions of environmentally harmful and health-hazardous substances to the air, to the ground and to water, are an undesired effect of many types of industrial activity. Our daily lives, too, result in the creation and spread of hazardous substances, in such ways as through the use of logs as fuel for heating, or the discharge of chemicals in waste water. Emissions also include chemicals from building materials and household products, as well as non-substantive emissions such as noise from traffic or machinery.
One of the working areas of the SP Group is the development of technology and new knowledge to reduce emissions and improve the quality of life. Examples of our expertise areas include emissions from biomass combustion, agriculture and food production, noise, industrial processes, water and effluent treatment, fire and other working areas. We use many different methods to measure and reduce hazardous emissions.
We have substantial expertise in most aspects of measurement, as well as in the chemical and physical characterisation of aerosols and sub-micron particles. We investigate the formation of emissions in combustion processes, together with related problems such as sintering, the creation of slag coatings at high temperatures and dust precipitation. Our expertise includes working areas such as the quantification of particle concentrations in dusty working environments and in everyday domestic indoor environments. We can measure emissions of volatile organic substances and formaldehyde from, for example, construction products, both in the laboratory and in the field.
Fire is another source of emission of health-hazardous and environmentally harmful substances. SP has many years' experience of characterisation of fire smoke from very differing sources such as domestic fires (furnished rooms), chemical stores, cables and vehicles, as well as of estimates of emissions to the environment.
An overall view of emissions and other environmental effects
The whole working area of emissions is complex, and in many ways associated with other problems such as that of climate effects. With its systems analysis expertise, SP can help to assess the overall perspective of the effects of emissions, and the use of resources for such purposes as the cultivation of foodstuffs or bioenergy crops, on environmental and climate mechanisms. These assessments help to show where improvements can have the greatest benefits, and what paths should best be pursued from both an environmental and an economic point of view.
