Which of the Following Substitutions Can Help Reduce Air Pollution



Pollution prevention and other ecology stewardship activities, such equally recycling and proper waste management, help ensure that Indiana’due south environs and economy are sustained for future generations.

Pollution prevention (P2) means working at the source of pollutants to forestall them from being generated or to reduce the amount generated. It is using materials and free energy more than efficiently, and conserving natural resource, including h2o. It is following best management practices, and involving all relative people in their implementation, to reduce and prevent pollution. Finally, P2 also means seeing the financial benefits of increased efficiency in the use of raw materials, energy, water or other resources. The “Pollution Prevention Hierarchy” illustration outlines the concepts of pollution prevention in the order of greatest effectiveness related to resource use and waste / pollution generation.

Defining Pollution Prevention (P2)

Source Reduction is whatsoever activeness that prevents the creation of solid or hazardous waste at the point of generation or minimizes the book and toxicity of waste material entering the waste stream. Source reduction is one of the main components of P2, and sometimes the term is used synonymously with P2.

The focus of P2 is conservation and waste matter minimization or elimination, not pollution control. Actions taken later on waste product has been generated, including out-of-process recycling, composting, treatment, concentration, or dilution, are non considered P2.

The “Waste Management Hierarchy” illustration demonstrates that the nearly desirable waste material reduction priorities are source reduction and reuse, followed by environmentally sound recycling and composting; energy recovery; treatment; and as a last resort, disposal or release (including unintended spills).

Since source reduction and reuse both result in the prevention of waste, the amount of waste requiring management is reduced overall. Waste reduction of these types are given the highest priority in solid waste management plans considering they reduce the demand placed on the management systems.

Pollution Prevention Includes:
  1. Any practice that (these practices are known every bit “source reduction”):
    • Reduces the amount of any hazardous substance, pollutant or contaminant inbound any waste stream or otherwise released into the environs (including fugitive emissions) prior to recycling, treatment, or disposal, and
    • Reduces the hazards to public health and the environment associated with the release of such substances, pollutants, or contaminants.
  2. Other practices that reduce or eliminate the creation of pollutants through:
    • Increased efficiency in the use of raw materials, energy, water, or other resources, or
    • Protection of natural resource past conservation.
  3. Equipment or engineering science modifications; process or procedure modifications; product reformulation or redesign; substitution of raw materials; or improvements in housekeeping, maintenance, training or inventory control.

To consider an “in-procedure” or “airtight-loop” recycling and / or energy recovery activeness a form of pollution prevention, it must serve a productive part with the making of the commercial product or the service provided for which the original procedure was designed. Such practices are only considered P2 if they become an integral role of the operations (i.eastward., the production process cannot function without the “in-process” recycling component).

Pollution Prevention Does Non Include:
  • Energy recovery that is external to the process
  • Recycling that is external to the process
  • Treatment of a waste matter stream
  • Disposal or release
  • Any practice that alters a chancy substance, pollutant or contaminant once it has been generated
  • Any practice that is not necessary for production
  • Practices that create new risks to human health or the surround
