Study Notes

Pollution Prevention

  • Pollution Prevention (P2) refers to techniques that reduce waste generation and associated environmental impact.

  • Incentives for P2:

    • Economic: Waste is viewed as a misplaced resource, reducing waste can save money in the long run.
    • Legal and Regulatory: P2 practices are often mandated by law, avoiding future liabilities.
    • Public Demand: Public pressure against hazardous waste production fuels change in legislation and consumer behavior.

Waste Minimization Strategies

  • Waste Minimization Audit:

    • Planning: Obtaining commitment from management, allocating resources, setting goals, and training employees.
    • Waste Characterization: Identifying specific waste sources, physical and chemical properties, generation rates, and current management methods.
    • Information Gathering: Utilizing process flow diagrams, material balances, operating manuals, equipment specifications, MSDS, material purchase records, production records, and maintenance records.

  • Pollution Prevention Methods:

    • Commonsense Waste Reduction: Immediate opportunities for reducing waste such as lowering water usage.
    • Information-Driven Waste Reduction: Replacing hazardous materials with less harmful alternatives.
    • R&D-Based Waste Reduction: Developing new processes and technologies to reduce waste generation..
    • Audit-Dependent Waste Reduction: Implementing changes based on thorough waste audits and analyses.

  • Housekeeping Changes:

    • Preventing waste streams from being mixed, especially for non-hazardous materials.
    • Maintaining separation of cooling water and waste streams.
    • Utilizing dry methods when possible.
    • Efficient waste segregation through equipment changes.

  • Reuse:

    • Repurposing contaminated materials for less sensitive applications.
    • Validating expired raw materials for reuse.

Toxicity Reduction

    • Powder coating technology replaces solvent-based paints, reducing hazardous waste.

  • Equipment Modification:

    • Optimizing equipment for smaller quantities of powdered chemicals to avoid waste.

  • Housekeeping Practices:

    • Ensuring proper storage areas for easy leak detection.
    • Comprehensive training for waste minimization implementation.
    • Encouraging employee suggestions for waste reduction.
    • Consistent labeling for waste identification.
    • Integrating waste reduction practices into routine facility inspections.

  • Material Substitution:

    • Using synthetic, recyclable lubricants instead of petroleum-based oils.

Recycling

  • Onsite Recycling:

    • Optimizes recycling practices by minimizing transportation and liability concerns.
    • Prioritize recycling within the facility to reduce transportation and disposal costs.

  • Water Recycling:

    • Recirculating process water for less sensitive applications within the facility.
    • Utilizing non-contact cooling water for reuse.

  • Solvent Recycling:

    • Implementing practices for recycling various solvents like alcohols, ketones, ethers, and hydrocarbons.
    • Utilizing cascade reuse, where solvents are used sequentially in different applications.

  • Oil Recycling:

    • Recycling contaminated oil rather than disposing of it as hazardous waste.
    • Reclaiming energy from spent oil through combustion in industrial boilers or furnaces.

  • Solid Recycling:

    • Recycling various solid materials such as paper, metals, and plastics.
    • Utilizing regular paper and paperboard recycling programs.
