In most of the western countries and developing countries are launching the new concept called the “ Recycling Malls ” in major cities and towns across their countries. The main objective of the recycle mart is to sell the used products (ex: used plastic, glass, paper, etc.). This is an innovative way of making things and helping in reducing environmental pollution in the surroundings across the globe.   There are different kinds of pollutions that are generated effecting Air, Water, Land, Food, Sea, Ocean pollutions. It is damaging the EARTH gradually and impacting directly and indirectly that are highly toxic and increase the scope of new harmful viruses etc.   Issue: Wastes are different types that are generated in the world which is mostly produced by man. Anything that is produced excess and unable to control is added into pollutant list. The recycling plants are getting adopted across the globe with different techniques, methodologies and Strategic ways in c...
