Alternate fuel research has been the topic of the highest priority in the context of depletion of fossil fuels at alarming rate and increasing of pollution levels of the engines with conventional fuel

In Little League dugouts, community parks, professional athletic organizations, and international soccer leagues, on college campuses and neighborhood playgrounds, even in residential yards, the question being asked is "grass or plastic?' The debate is over synthetic turf, used to blanket lawns, park spaces, and athletic fields where children and adults relax and play; the questions are whether synthetic turf is safe for human and environmental health, and whether its advantages outweigh those of natural grass.

The cluster of beige corrugated-iron sheds and silos don't look like much, but this unassuming factory in a suburb of Melbourne, Australia, represents a potential revolution in greenhouse gas emissions. It's the first commercial enterprise in the world dedicated to transforming waste from power stations and blast furnaces into geopolymer concrete, a particularly promising green concrete.

In view of the environmental problems generated by large-scale production of fly ash, increasing attention is now being paid to the recycling of fly ash as a good source of nutrients. Because
availability of many nutrients is very low in fly ash, available ranges of such nutrients must be improved to increase the effectiveness of fly ash as a soil amendment. In our experiment, we assessed the possibility of increasing total nitrogen, total phosphorus, total potassium and micronutrients in fly ash through

Recycling

Enriched compost produced with use of municipal solid wastes (MSW) recorded narrow C:N ratio at the end of decomposition period than municipal solid wastes decomposed without enrichers. To enhance the decomposition rate, quality of municipal solid wastes and enrichers/amendments are found very significant for production of compost.
