We at Technogreen have firm belief that the life of humans is full of novelty & modernization. Creativity is the basis of human life. Man has been so developed, as to create new ideas, technologies, solutions, etc. & implement them to meet the new or existing requirements. The end user is ultimately the society, markets & governments, so as to make these systems simpler with the use of the advancements. Pursuing this fact of human race, TES is constantly involved in developing new ideas in this extremely vast & challenging field of environmental sciences. Our aim is to provide a new dimension to the existing system which will serve the industries & society towards a better living.
Traffic related pollution have been studied for long and several policy interventions in terms of fuel change, alternative fuels, vehicle technology improvements, cleaner fuel, etc. & implemented from time to time to reduce pollution from this sector. Nevertheless, even after all these interventions, due to the exponential growth of vehicle in cities have witnessed enormous potential of pollution through high density development leading to creation of bottlenecks at several traffic junctions. On the Other hand, Cold Start and idle emissions from vehicles is also one of such indoor air problems that have been witnessed in India recently and not much attention has been given to the same needless to say the ever increasing contribution of outdoor air to indoor spaces. There is an urgent need to assess the status and plan for remedial measure since these concentrations of pollutants in terms of gases sometimes reach to lethal concentrations (acute exposures) in presence of limited or no ventilation.
Department of Environment along with MPCB and World Trade Center recently conducted Conference cum exhibition on “Pathway Towards Formulation of Science Based Environmental Policy for State of Maharashtra” on the eve of Earth Day 22nd April, 2016. The concluding agenda of conference was extended by the Hon’ble Addl. Principal Secretary and Member Secretary to prepare an exhaustive list of such interesting technologies having potential for environmental management in near future.
One such technology that could serve as an easy and effective solution to fugitive sources of air pollution is “Yuka Yantra” an unconventional technology to treat the indoor air & its successive variant in form of - 3 stage virtual chimney for traffic junctions as one of end of the pipe air pollution abatement mechanism. The unit is a blend of a unique methodology using low temperature catalysis with a combination of Advanced Oxidation Process and adsorption as one of the pioneering technologies for air pollution cleaning in closed spaces of building as well as in terms of virtual chimney at traffic junctions.
Human development have always been responsible to resource usage in an unplanned fashion over the ages which has now lead to policy makers think in the direction of sustainability of mankind itself. The growth of population and resource constraint followed by exploitation of nature and its potential has lead to a questioning of carrying capacity of the mother earth. Recent changes in the climate has lead people rethink about their very existence since pollution has become a global issue and especially considering the trans-boundary effects of certain pollutants realized lately. A lot has been talked about the same though nothing has been done much about it. It is high time that some initiative has to be taken up to carryout capacity building programmes which rather we call it as SENSITIZATION programmes for various organisations enhancing their Corporate Social Responsibility and believing that sustainability can never be brought about through agencies but it has to born in the minds of people that every individual shall contribute for remaking of this earth to utilize its resources for our present & conserve enough to be sufficient for our future generations vis a vis development. The benefits is global and not limited to individuals as each individual taking part in this process will be setting up trend for the entire world to take up individual efforts which is the only way to save the earth from the deadly effects of global climate change.
With the increasing densities of urban areas, it is inevitable for builders to go vertical for building structures in order to accommodate maximum population in comparatively smaller footprint of construction. Though this has been more evident in metropolitan cities like Mumbai, the same has led to certain scenarios of unacceptability factors categorized in 3 major sectors viz; traffic bottlenecks, pollution hotspots & reduced dispersion of pollutants.
People have been facing critical issue of pollution hotspots at several locations which may lead to complications of severe origins. The dispersion analysis studies carried out in the past shows that the basic flaws of high background traffic and creation of some bottlenecks around the site leading to excessive concentration build-up at certain receptors at junctions which may form considerable concerns. The basic problem as understood from assessment of secondary data that even if the project related emissions from traffic may not be of serious concern at present, the cumulative traffic and projections for the site related study area may result in serious concerns of pollution indicators.
There may be options available through policy mechanisms of mitigating pollution through smoothening of traffic via more efficient synchronization or road widening, etc. but most of these methods are already in place and some of them being planned may not result in the thorough cleaning of air around the site based on the earlier studies in metropolis. Conventional methods of such pollution control through technology improvement, fuel improvement, signal synchronization, etc. are already in place not only in metropolis but other major cities also, and thereby its effective performance on ever growing hotspots may be irrelevant in this case. There is a need to seek some unconventional options.
While most media attention has focused on outdoor air pollution in the last few years, indoor air pollution is typically under-reported and less regulated than its counterpart. A cursory glance at news reports and government reports in recent years on buildings with poor Indoor Air Quality (IAQ) suggests that the number of IAQ-related health complaints, and therefore, the costs of insurance and litigation to redress these problems, is significant, and perhaps rising.
Environmental Protection Agency studies of human exposure to air pollutants indicates that indoor levels of pollutants may be 2 – 5 times, and occasionally more than 100 times, higher than outdoor levels. These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their times indoor. Research has shown greater exposure to indoor air pollutants in economically developing countries based on income, and in some cases greater occupational exposure to air pollutants for those in lower income brackets. In addition to exposure, baseline health status and health-related behaviors differ depending on the socioeconomic factors.
Cold Start and idle emissions from vehicles is one of such indoor air problems that have been witnessed in India recently and not much attention has been given to the same. There is an urgent need to assess the status and plan for remedial measure since these concentrations of pollutants in terms of gases sometimes reach to lethal concentrations (acute exposures) in presence of limited or no ventilation. Self sustaining system with multiple treatment system philosophies shall be employed to solve the problem of parking area related static / semi-static pollution. The system shall use adsorption as well as alternative means of low temperature catalysis and / or photochemical oxidation (AOP).
