Resource Management


Don’t we feel embarrassed at accumulated waste? Don’t we feel the need of reusing it? We are approaching to a world where Waste would need to be managed optimally. The Problem is to develop a system for sitting purposes out of waste resources or commonly available not in use materials.
Recycling is a process that involves processing used materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production. Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.
Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics.
One can approach this to make the use of other available stuff for useful purposes.

Thus, design a complete system/device made from recycled material which provides a new and more efficient way of using the recycled material to form a new device. The cost-efficiency and innovativeness of the device would be given more weightage.

SOIL AND WATER CONSERVATION

Rainwater harvesting is the gathering, or accumulating and storing, of rainwater. Rainwater harvesting has been used to provide drinking water, water for livestock, water for irrigation or to refill aquifers in a process called groundwater recharge. Rainwater collected from the roofs of houses, tents and local institutions, or from specially prepared areas of ground, can make an important contribution to drinking water. In some cases, rainwater may be the only available, or economical, water source. Rainwater systems are simple to construct from inexpensive local materials, and are potentially successful in most habitable locations. Roof rainwater is usually of good quality and does not require treatment before consumption.
There are a number of types of systems to harvest rainwater ranging from very simple to the complex industrial systems. Generally, rainwater is either harvested from the ground or from a roof. The rate at which water can be collected from either system is dependent on the plan area of the system, its efficiency, and the intensity of rainfall.
Suggest such methods for conserving water in the both rural and urban areas such as rainwater harvesting, but more cost-efficient and effective than the ones available with us. Then develop a complete method to implement it and also find out the financial details involved.
