So, thought Sjouke Postma, the managing director of a Hong Kong-based firm called Hednesford, why not dispose of one pollutant (waste cooking oil) by burning it in diesel engines and thus reducing the level of another pollutant (vehicle fumes).Of course, it is not quite that simple.
The combination of municipal sewage and industrial waste discharges coupled with an expanding economy required that pollutant waste loads be reduced.
The preparation of polymeric composites from recycled thermoplastic with natural fibers is an interesting alternative that contribute for preservation of natural resources, decrease of pollutant waste and production of low cost materials.
These processes and subsequent refining result in pollutant waste.
Another approach for reducing the production costs is developing processes which use renewable lowcost raw materials or high-pollutant wastes.
According to citizens' opinion, environmental sustainability and liveability are the most relevant issues (see Tables 3 and 4): reducing greenhouse-gasses, air pollutants, waste and accidents from transport are considered as priority by more than 58% of respondents.
An effective cleaner production programme requires the efficient collection and interpretation of data relating to a facility's activities, including information of pollutant emissions, wastes generated and raw materials consumed.
Prior studies (Post and Obirih-Opareh 2002; Oteng-Ababio et al. 2013) have shown that waste management remains the single largest item on the assemblies' budget yet the most pernicious local pollutant (uncollected waste remains the leading contributor to local flooding and pollution).
The strong magnetic performances would be helpful to the removal of heavy metal ions or organic pollutant in waste water.
Precipitation absorbs gases and particulates from the atmosphere, dissolves and leaches materials from vegetation and soil, suspends matter from the land, washes spills and debris from urban streets and highways and carries all these pollutants as wastes in its flow to a collection point (Luo et al. 2008).
