Pollution Prevention Introduction
Collision Repair Curriculum
Paid for, in part, by the Kansas Department of Health and Environment
Pollution Prevention (P2)• True P2 is reduction at the source of
generation– Solid and hazardous wastes– Air emissions– Wastewater contaminants
• 1990 P2 Act– Established new hierarchy for waste management
2
P2 Act of 1990
Shifted the focus from “end-of-pipe” pollution treatment and cleanup, to policies, technologies, and processes which prevent and minimize the generation of pollution
3
P2 Act of 1990• P2 Act says:– Pollution should be prevented or reduced at the
source whenever feasible– If not preventable then recycled in an
environmentally safe manner– If not recyclable, should be treated to be less
hazardous– Disposal into the environment is a last resort
4
Why do P2?• Reduce regulatory responsibility• Reduce wastes and emissions, thus liabilities• Reduce raw material use or losses• Reduce energy consumption• Reduce operating expenses• Reduce insurance rates• Safer work environment• Enhance good will and rapport with regulators
and your neighbors
6
Pollution Prevention (P2)
• Can be accomplished through several methods:–Change in process (work practices)–Change in materials–Change in technology
7
Change the process• Changing how someone works – Cheapest approach possibly– Hardest (that’s the way we’ve always done it!)
• Examples: Manage inventory Color matching Close paint and solvent containers Improve paint measurement and mix only what’s
needed
8
Change the process• The painting process
Follow paint and spray gun manufacturers’ instructions
Operate spray equipment within regulated pressure limits
Follow operating and maintenance procedures for your spray booth and curing equipment
Consider using tintable primer systems to improve color matches and to get complete coverage with fewer coats
9
Change the process• The painting process (cont.)
Schedule waterborne primer work for the end of the day
Remove the body part from the vehicle before painting
Continue to improve your spray application technique and transfer efficiency
• The paint booth Perform routine maintenance on filters
10
Change the material• Use a different chemical/substance to
accomplish the same result• Use the least hazardous material• Example:– Consider using waterborne paints– If paints contain heavy metals, consider using
alternatives, if available
11
Change the technology• Many new technologies promote P2 by
building waste reduction into new equipment by– Increasing efficiency/material utilization– Internal reuse of chemicals or materials– Mechanizing a process– Using a different “science” to achieve same results
12
Change the technology• Examples:– Upgrade spray equipment• Does the gun operate effectively within the required
pressure range?• Can it achieve the required transfer efficiency?• Is the spray gun approved for use by air regulations?
13
Change the technology• Examples (cont.):– LaserPaint• Iowa Waste Reduction Center developed• Attaches to any spray gun• Helps painter maintain correct angle and distance,
optimize overlap, and reduce overspray
14
Good P2 projects• Easily defined goal• Maximum two year payback or less• User friendly and adaptable to existing
operations• Measureable results• Reduce impacts to environment and improve
health and safety of employees
