Food waste is approximately 14% of the household waste we discard. Food waste is of concern to environmental agencies and municipalities because in landfills food waste is a primary cause of methane gas emissions, a very potent greenhouse gas, and the methanogens that food waste supports in landfills also cause the mobilization of other pollutants in landfills, resulting in an increase in both air pollutants and leachate.

A new report, developed by Eunomia on behalf of Zero Waste Europe, says that better waste management can help in reducing emissions of greenhouse gases, but that this is “being obscured by current statistics”.
One of the authors, Ann Ballinger, said: “Our calculations make clear that if we manage waste in the way that the EU has been proposing, we can cut greenhouse gas emissions by the equivalent of around 200m tonnes of carbon dioxide a year by 2030 – the same as the annual emissions of the Netherlands.” Read more
JAIPUR: Garbage dumped in and around the Jaipur railway station premises would help cook food and run trains in the near future.
Authorities of the North Western Railways (NWR) are coming up with two waste plants not only for the disposal of solid bio-degradable waste but also for the disposal of plastic. It will also be used for energy generation. The officials said that both the plants would be operational at the Jaipur railway station within this financial year. Read more
Sea turtles are vulnerable to ocean pollution at all stages of life, from eggs to hatchlings to juveniles to adults. Pollutants include things like toxic metals, pcb’s, petroleum products, and agricultural and industrial runoff of contaminants such as fertilizers, chemicals, nutrients, and untreated waste. Pollutants may cause immediate harm to sea turtles through direct contact or can build up in tissues over time and lead to immunosuppression resulting in disease and death. Read more
Growing amounts of waste put an increasing burden on the climate, particularly in newly industrialising countries, where greenhouse gas emissions are rising, according to a new study for the German environment agency. EurActiv.de report
While Germany has been able to reduce harmful emissions through waste processing, the waste management industry in many developing and newly industrialising countries, as well as in numerous OECD countries and the United States, could do much more to contribute to climate protection. Read more
The basic methods of concentration and purification of liquid radioactive waste on the nuclear power plant are distillation and ionic exchange. During vaporization of oil waste products and the fulfilled washing solutions the part of oil passes into a condensate. Clearing of such condensate on ion-exchanged filters results to oiling of ion-exchanged materials and to decrease number of filter cycles. Due to the often regeneration of ion-exchanged filters additional volumes of waste products as the fulfilled reclaiming solutions, washing and loosening waters are formed. The attention of scientists was involved with methods of clearing of water environments from the organic substances, based on deep oxidizing transformations of hydrocarbons into carbonic gas and water. From processes of oxidation of hydrocarbons up to CO and HO, sold at moderate conditions, our attention has involved photochemical oxidation with the help of UV-radiation.
The production of waste in India is growing at an exponential rate. However, the welfare and dignity of the informal workers involved in the stigmatised sector of waste management remains at the bottom of any government’s political agenda.
Human society has always produced waste and always will. Waste materials — substances without value — are constantly generated in all production, all distribution and all consumption processes. The time waste spends without any value may be a few minutes at the minimum and, at a maximum, eternity. Nature, the key provider of resources, is not simply a tap. In subjecting waste to the physical laws of decomposition and re-composition, it also acts as a sink. Many bio-physical processes take place at an extremely slow rate, compared to the rapid physical cycles of the economy. My 2015 fieldwork on the waste economy of a small town indicated that about half the waste could not be recycled and was left to nature’s sinks. Read more
- Step 1 : Segregated waste accumulation
(Pre and post kitchen waste (veg and non veg),
Garden waste (twigs upto 20 mm, dry leaves,
dry grass, garden cutting)other waste – tissue paper,
card board, paper etc.
- Step 2 : Shredding of the total mixed waste.
- Step 3 : Output from shredder in the form of pulp.
- Step 4 : Pulp laoded to digester.
- Step 5 : Worms eating the pulp (composting process)
- Step 6 : Fall out of worms in the form of manure
- Step 7 : Manure used in garden
Almost after completion of 15 year into the 21st century we still know Dussehra (Dasara), is a famous Hindu festival that seeks to celebrate the victory of good over evil. But the question is,” Is evil the same in this 21st century?” The answer is no, the evil has changed and it is far more evil and disruptive than it was then. Read more
Inadequate waste management has become a major public health, economic and environmental problem, with 7-10 billion tonnes of urban waste produced each year and 3 billion people worldwide lacking access to controlled waste disposal facilities. Fuelled by population growth, urbanization and rising consumption, the volumes of waste are likely to even double in lower-income African and Asian cities by 2030, warns the Global Waste Management Outlook – launched by the United Nations Environment Programme (UNEP) and the International Solid Waste Association (ISWA) today.
