How can I produce less hazardous waste?

Try these tips for a less-toxic household!

  • Buy only the amount of paint and cleaners you need.
  • Use up materials for the purpose they were intended.
  • Buy latex paint instead of oil based paint. It is easier to cleanup and easier to recycle.
  • Buy non-toxic or the least toxic product that will do the job.
  • Read the label! Avoid products that are marked “dangerous” since they are usually the most toxic.
