Sandia goes beyond basic recycling of common papers, plastics, and metals. We divert as many waste streams for recycling as feasible. The list of materials diverted grows every year. We regularly re-evaluate processes for efficiency and improved revenues as well. Revenue received from recycling goes back into the program to fund material streams that currently cost to process, and to improve and expand the waste reduction infrastructure.
The state of New Mexico has a target to recycle 35% of its waste by 2018. The Department of Energy has a goal of 50% by 2015. Sandia/New Mexico is contributing toward both of these goals by recycling nearly 71% of its waste in FY12. Sandia/California is doing even better at 78%.
Sandia/New Mexico sends green waste in the
form of branches to Kirtland Air Force Base’s mulching program. Additionally, sensitive documents are destroyed onsite and the remains
are sent to a local composting company. In 2010-2011, the green waste
and composting efforts began and expanded greatly.
To reduce green waste going to the landfill, two large rolloff
containers were strategically placed on campus to receive any green
waste not eligible to be mulched (leaves, grass, trimmings). When full,
these containers are hauled to a local composting facility. As
needed, finished compost is simultaneously purchased by the truckload to
save on return transportation. To reduce the volume of grass clippings
and leaves, campus landscapers purchased two new mulching
lawnmowers using recycling revenue.
Building on momentum from a 2009 waste audit, a
six-month pilot of food waste composting from the main dining facility
was completed in 2010 — it diverted more
than 25% of the facility’s waste. The pilot was converted into an
ongoing contract, and at Earth Day 2011 it expanded to the satellite café
on campus. Diversion continues to improve, most recently reaching 66%
of the two facilities’ waste.
If computer and laboratory equipment don't find a reuse at Sandia, audited pathways exist to move the material offsite to be reused by other federal agencies, donated
to New Mexico K-12 schools, sold at a local auction, or recycled domestically.
Unusable ISDN telephones previously
sent for recycle along with computers are now carefully
separated and shipped for free to a vendor that refurbishes the phones. Any leftover telephone scrap is recycled.
Computers, peripherals, and accessories for recycling go to an R2 Certified Facility. Circuit boards are sent to a precious metals recovery vendor. Currently being explored is the diversion of hard drive magnets for the
capture and sale of the neodymium (“rare earth”) material.
