Contact the Direct Marketing Association (DMA). DMA is the oldest and largest trade association for the users and suppliers in the direct, database and interactive marketing field. You can use the DMA website to request their no cost Mail Preference Service (MPS). With DMA's MPS you can remove your name from DMA member prospect lists. Please note that signing up with MPS may prevent you from receiving mail you want, such as new catalogs, coupons, announcements about new businesses in your community, and notices of special offers. But, this can significantly reduce your “junk mail” load (at least 75%).

If you want to REDUCE your paper MSW, here is an easy first step:

But most (54%) of our MSW still goes to landfills…

Eventually these have to be closed…

• 5% of plastics by total weight

• 50% of aluminum cans

• 65% of steel

• 31% of glass containers

Why would recycling rates vary so much by material?

Why Don’t We Recycle More?

• Environmental costs are not passed on to consumers in market prices (cheap goods)

• Most government subsidies are for those extracting virgin materials

• Fees/charges for dumping in landfills are low

• Lack of large, steady markets for all recycled materials (varies by material)

• Source separation inconvenient?

Solutions?• Taxing virgin resource extraction and ending

mining subsidies?• “Pay-as-you-throw” systems?• Requiring government funded agencies to

increase demand and lower prices by purchasing more recyclables?

• Pass “take-back” (cradle-to-grave) laws for manufacturing (like some European nations)?

• Labeling of postconsumer vs. preconsumer recycled content?
