Waste is unwanted or undesirable material leftover or thrown after the completion of any process. In other words, it can also be stated that any substance or matter which the holder discards or intends to discard is waste or which is generally not used again. Waste management can be done through the 3R (Reduce, Reuse, Recycle) Principle also.
Some of the waste which is commonly seen are around are :
Yash Krishi dose has worked with the field of Biodegradable waste and two types of Non Biodegradable waste namely C& D waste and Polythene waste. In this regard a relevant article entitled “Getting Ready to Plan the Future Townships though Renewable Material and Technology” is attached. In this article waste like C&D, Fly Ash, Silica Fume, Blast Furnace slag, Red mud Etc.
It is one of the wastes which come from all Hospitals and Nursing homes. There are large varieties of medicines and their associated storage glassware or syringes’ which have to be destroyed. No 3R principle of waste management can apply for such waste.
Out of the various type of waste Yash Krishi……. has dealt with only two types of waste is Bio degradable waste & two non-Bio degradable wastes.
“Composting” is the biological decomposition of lingo-cellulosic organic material like solid wastes, press-mud, etc – into a simple compound/humus-like end product called “compost”. The product is of value in agriculture both as an organic fertilizer and as a soil improver. It is used as an organic manure for moisture control and nutrient addition.
Following two steps are necessary for Processing of waste
“Yash Activator Plus”- a microbial consortium has been developed by Yash Krishi – which is highly effective in composting press-mud, flowers and other biodegradable material collected from the ground, rivers/temples, and used in STPs, etc. The process of Bio-degradable waste converts into manure is given below.
There are large Varieties of Non-Bio-degradable waste available in all places like Roadside, Industry, Hospitals, polythene waste, Construction sites, etc. Techniques for two types of Nonbiodegradable waste have been developed to convert them to items like resources by YASTK: Following two wastes have been tried
The process of treating this waste into useful materials like bricks, Interlocking Blocks, Perforated Blocks, etc has been developed. The process of these is given in the article and technology is also available on-demand to entrepreneurs.
Such Polythene waste can also be used for making Perforated Polymer Concrete blocks or slabs for rain water harvesting from Road sides, parking lots, etc as shown below. This is done by heating a small size of aggregate and heating it. On heated aggregate, the waste polythene pores as described in the article.
