Answer: increasing demand for a product.
Step-by-step explanation:
Recycling is a process of conversion of a useless material into a form so that it can be used again. It is associated with the reuse of materials like aluminum cans, wooden items. This process reduces the dependency of the human society largely on resources. It reduces the cost of generation of the new materials as the ingredients used for construction were used previously. It reduces the concentration of wastes from the landfill as majority of the used materials can be reused for the preparation of the new materials. It also reduces the cost of energy required for the generation of new ingredients.
On the basis of the above explanation, increasing demand for the product is the correct option.
