This study investigated the use of effective microorganisms (EM) for enhancement of biogas production through composting of solid pyrethrum remains after extraction of pyrethrins (marc). The laboratory scale experiment involved composting of the waste as substrate mixed with EM at different ratios consisting of a control, substrate with EM at of 1:250, 1:500, and 1:1000 v/v. Results show highest production of biogas at EM ratio 1:500 v/v, while biogas produced at EM ratio of 1:250 v/v had the highest methane yield.

Leaking underground storage tanks (USTs) containing gasoline represent a significant public health hazard. Virtually undetectable to the UST owner, gasoline leaks can contaminate groundwater supplies. In order to develop remediation plans one must know the extent of gasoline contamination. Centrifugal simulations showed that in silty and sandy soils gasoline moved due to the physical process of advection and was retained as a pool of free products above the water table.

Energy efficiency and the profitable use of biomass residues are often demonstrated by pulp and paper factories, which are forerunners in this area. A new example is given by Dalkia and Metso, global players in bioenergy service and technology in France.

Organic farming is gaining wide attention among farmers, entrepreneurs, policy makers and agricultural scientists because it minimizes dependence on chemical inputs like fetilizers, pesticides and other agro-chemicals and safeguards and improves the quality of resources and the environment.

The Jaipur Municipal Corporation (JMC) will draft bylaws for enforcing Greenline service on all restaurants and hotels in the city.
Under this service, JMC's vehicles will collect garbage and wastes from eateries and transport it to compost plant at Sevapaura.
Launching the service, city mayor Jyoti Khandelwal talked about benefits of the Greenline service on Wednesday.

Agricultural  application  of  Municipal  Solid  Waste  (MSW),  as  nutrient  source  for plants and as soil conditioner, is the most cost­effective option of MSW management because  of  its  advantages  over  traditional  means  such  as  landfilling  or  incineration.

The present laboratory study reports the results of various engineering properties, such as compressive strength, tensile strength, flexural strength and impact strength of fibre reinforced concrete produced from waste plastic fibres and flyash which are the two environmental pollutants.

KOCHI: Soon electricity and bio-products will be produced from solid waste in Kochi. Loro Marketing and Trading Pvt Ltd, an Abu-Dhabi-based business group of NRIs, is coming to Kochi with a project to produce electricity and bio products from solid waste with the aid of Irish-based Wilson technology, known for waste management and green energy production.

THIRUVANANTHAPURAM: A scheme to supply the bio manure produced from the city garbage to households has been launched by the Thiruvananthapuram Corporation. The programme was inaugurated by Ports Minister V Surendran Pillai at the Press Club here on Thursday.

Speaking at the function, the Minister lauded the unique venture.
