Although an Eco-friendly process and one of the important ways to save the environment, recycling is not gaining pace in the industry. The recycling undergoes many process. First is collecting and sorting of garbage. This required a lot of manpower and tools which are expensive. Another disadvantage of recycling which makes it unviable is that for the manufacturers economically, the recycled material is not highly demanded since its quality is not as good as the original material. So, if the marketing of recycled goods is not worthwhile then the whole process of recycling cannot be economically efficient. Recycled products face other disadvantage as well, such life, difficult in de-linking the dyed products and less durability etc.
Why is the marketing of recycled products not worthwhile according to the author ?
1. The original products are being sold at a much lower price as compared to the recycled products.
2. The overall effects of recycle on the environment is detrimental rather than beneficial.
3. It does not give appropriate economic returns since recycled products lack demand in the market.
