BetterWorld Books Metrics
Check out our metrics from Better World Books in the past year. Through our partnership we were able to reuse or recycle 294 books saving 4 trees, 3,257 gallons of water, and 631 pounds of greenhouse gases.
How can you help? Bring us your books you no longer want. We'll see if Better World is interested. Buying books? Go to the link on our home page to go to Better World and we will get a commission.

EXPLANATION OF DATA VALUES
BOOKS – This category is made up of the sum of books sold and donated.
The reuse of these books is considered waste prevention. Reducing the
volume of waste we create results in limiting the environmental impact
of disposal or recycling¹.
BOOKS – Books we deem unsalable and not appropriate for donation to our
participating literacy partners. Recycling books is termed waste
reduction¹. Our recyclers report that the efficiency of recycling a
book yields 97% of that book as usable fiber.
OF BOOKS – The average weight of the outbound books that Better World
Books has processed is 1.37 pounds. This average weight is multiplied
by the number of books categorized as ReUsed. Recycled books are
multiplied by the efficiency rating of generating recycled fiber (see
Usable Fiber below).
– The number of typical trees assumes a mix of hardwoods and softwoods
6-8inches in diameter and 40feet tall. The number of trees saved per
ton of 100% recycled fiber produced is twenty four².
(g) - There are 8,750 gallons of water saved per ton of paper produced
when comparing 100% forest fiber sources to 100% postconsumer fiber².
& GREENHOUSE GASES (lbs) – Landfilling produces .725 pounds of
methane per book³. One way of measuring the impact of greenhouse gases
is by assigning them a Global Warming Potential (GWP). The concept of a
global warming potential (GWP) was developed to compare the ability of
each greenhouse gas to trap heat in the atmosphere relative to another
gas. The definition of a GWP for a particular greenhouse gas is the
ratio of heat trapped by one unit mass of the greenhouse gas to that of
one unit mass of CO2 over a specified time period*. Methane has a GWP
of 25 which makes this particular emission a greater cause for concern
than CO2. The total greenhouses gases, including Methane saved in
production of one ton of paper from 100% postconsumer fiber versus 100%
forest fiber sources is 2108 pounds²
SPACE (cu yd) – 1 ton of books takes up 3.3 cubic yards of space in a
landfill². The total pounds divided by 2000 equals total tons. Tonnage
multiplied by 3.3 cubic yards and multiplied again by the 97%
efficiency rating of postconsumer content paper yields the total cubic
yards of space conserved.
– There are 4893 Kilowatt Hours of electricity saved per ton of paper
produced when comparing 100% forest fiber sources to 100% postconsumer
fiber². The conversion factor utilized was 1 Btu = 0.00029307108333
of Usable Fiber – Our recyclers report that 97% of the books that we
send are turned into usable fiber. This 3% of refuse is used in
calculation of any pertinent metrics. The total pounds of Recycled
books divided by 2000 yield the total tonnage of usable fiber.
