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:
- Segregating hazardous waste to prevent mixing.
- Training employees to implement new procedures, including proper labeling.
Volume Reduction
-
Process Modification:
- Raw Material Substitution: Replacing hazardous materials with less harmful options.
- Equipment Changes: Upgrading or modifying equipment to reduce waste generation.
- Operating Procedure Alterations: Optimizing processes to minimize waste.
- Material Storage Optimization: Efficient storage to avoid waste.
- End Product Optimization: Modifying product designs to reduce waste.
-
Segregation:
- 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
-
Process Modification:
- 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.
