ISSUES ON COSTS AND INVESTMENT FOR ENVIRONMENTAL PROTECTION

The concept of sustainable development has emerged in order to correlate the need to continue increasing the level of human and increasingly fragile "health" level of environment. At the industrial level, things have moved more quickly. Thus, many companies use waste as fuel, and in some localities they are trying to implement systems for heating cottage on the combustion of waste. They are first to have acknowledged the eco-economical importance of recovery and reuse waste. Researchers draw attention to the conflict between industrial civilization and environment and mention two aspects: the tendency of depletion of natural energy resources, raw materials and food or renewable consumption on a pace above their capacity of regeneration and physical damage and pollution of the environment: water, air and land, All efforts for avoiding pollution or to protect the remaining resources quantify the money spent by the private and public sector. There should be a directly relationship between expenditure and the environment "health" state. The involvement tendency of increasingly amounts for environmental protection should create cleaner and less polluted environment.
