Reduction Program

Monsanto is committed to being a leader in reducing waste discharges to the environment. The Company announced in June 1988 a commitment to reduce air emissions of hazardous materials by 90% by the end of 1992. In addition, Monsanto Agricultural Company established a further goal to reduce the discharge of organic and hazardous inorganic materials to all environmental media. Projects have been identified for the Agricultural Company to achieve the 90% air emission reduction goal and to reduce projected 1995 waste discharges from 150 million pounds to 50 million pounds.

Abstract This article presents data on the anthropogenic air emissions of selected substances (CO2, SO2, total suspended particles (TSP), dioxins and furans (PCDD/F), Pb and Cd) subject to reporting under the Climate Convention (UNFCCC) or the Convention on Long-range Transboundary Air Pollution (UNECE CLRTAP). It also presents the national emissions of these substances in 2014 by the major source categories and defines the share of metal production in these emissions. Analysis is based on national emission inventory reports. Most important source of air emission in case of CO2 and SO2 is 1.A.1 Energy industries category. TSP and PCDD/F are emitted mainly from fuel combustion in small sources (i.a. households). Emission of heavy metals (Pb and Cd) is connected mostly with 1.A.2. Manufacturing industries and construction category. Metallurgy is significant source of emission only for lead and cadmium from among all considered substances. The shares of particular sectors in the national emissions of given pollutants are important, in view of the possible reduction measures and the determination in which industries they could bring about tangible results.

A speech disorder that occurs due to deformities of speech organs, especially articulators, is called dysglosia. The congenital deformities of speech organs of people around us result in various difficulties in communicating due to inaccuracies or inconsistencies in articulating words. One of the methods in the field of speech therapy being able to to overcome the problems including the abnormalities in sound resonance is Cul-de-sac (Nose Pinching) method. This study aimed to determine the effect of the application of the Cul-de-sac (Nose Pinching) method in increasing the awareness of Dysglosia clients about the differences in sound resonance in the nasal cavity and oral cavity when producing consonants and reducing nasal air emissions when producing consonant sibilant apicoalveolar / s. / at the Cleft Center Bandung. The research method used is single subject experiment. Data were collected through interviews with the client's parents, direct observation of the client, tests, and a document study of the client's medical record. After 15 sessions of therapy using the method, the client's ability had improved for about 65% and he was successfully able to pronounce the consonant of / s / in the presence of a nasal air emission between 1-2 cm. Therefore, based on the results it can be concluded that the Cul-de-sac (Nose Pinching) method has influenced as much as 65% of nasal air emission reduction.

Alcoa World Alumina Australia has undertaken comprehensive air emissions monitoring aimed at characterising and quantifying the complete range of emissions to the atmosphere from Bayer refining of alumina at its Western Australian refineries. To the best of our knowledge, this project represents the most complete air emissions inventory of a Bayer refinery conducted in the worldwide alumina industry. It adds considerably to knowledge of air emission factors available for use in emissions estimation required under national pollutant release and transfer registers (NPRTs), such as the Toxic Releases Inventory, USA, and the National Pollutant Inventory, Australia. It also allows the preliminary identification of the key chemical components responsible for characteristic alumina refinery odours and the contribution of these components to the quality, or hedonic tone, of the odours. The strength and acceptability of refinery odours to employees and neighbours appears to be dependent upon where and in what proportion the odorous gases have been emitted from the refineries. This paper presents the results of the programme and develops a basis for classifying the odour properties of the key emission sources in the alumina-refining process.

The City

Together with the urbanization, industrial activities are increasing and transportation system is being rapidly developing. In 2017, the population of Ho Chi Min city (HCMC) is over 8.6 million. The city has 8 million vehicles including 637,323 automobiles and more than 7,339,522 motorcycles. Up to now, the city has a total of 2708 factories generating air emissions (including 3 processing zones (EPZs) and 16 industrial parks (IPs), with thousands of factories outside the IPs / EPZs), resulting in an increase in emissions from these activities and affecting the air quality of the city. Therefore, in this study (i) collect air emission data, evaluate and calculate of air emissions by applying EMISENS emission calculation models and survey and traffic counting methods; (ii) Develop clean air action plan and climate change mitigation for Ho Chi Minh City. The results showed that on-road activities are the major contributor, accounting for 88% of NOx, 99% of CO, 79% of SO2, 99% of NMVOC, 88% of PM in total emissions from transportation activities. Key finding in this study is that harbour activities contribute up to 20% of total SOx and 10% of total PM. Other sources (airport, harbour, bus station, rail way) only accounting for negligible amount of emissions. Emission maps showed that emissions in harbours and in central areas of the city as District 1, district 10, district 3 and district 5 are higher than the other districts. This study has also developed 13 measures to effectively manage air quality and reduce GHG in Ho Chi Minh City.

The performance of an industrial prototype of a biological system was investigated during more than two years, for the treatment of exhaust gas from air emission of wooden painting activities. Two different type of VOCs mixture were treated at different weather conditions. Removal efficiencies were sufficiently high to maintain the outlet emissions within the legal thresholds. Particularly low costs for management were experienced, confirming the biofiltration a sustainable technology.
