Reduce Reuse

Recycle

Houston’s recycling:National MSW

disposal:54% Landfilled34% Recycled12% Incinerated

Houston MSW disposal:

86% Landfilled14% Recycled0% Incinerated

Houston’s “One Bin for All”ALL waste in one binOne truck instead of four (MSW, yard waste, recycling,

heavy trash)Materials sorted in $100 million state of the art facility to

be built by private companyConstruction to begin next yearCould divert 75% of material from landfill (resold by private

company)Biomass (yard, food, clothing and plastics) converted into

biofuels First of its kind in the nation. Could set new standard.Would include an incinerator.

Should the city move forward?Those in favor Those againstMayor and city

sustainability coordinator

Environmental Defense Fund

Clinton Climate InitiativeKeep Houston Beautiful

Texas Campaign for the Environment calls the plan “Anti-recycling” and “a pipe dream”. Concern that the city will end up having to pay for the construction and that technologies are unproven.

Are we being “greenwashed” or is this a step towards waste = food/cradle to cradle/ sustainability?

What is the standard recycling practice?

Recycling in three easy steps

Collection

Reprocessing

Repurchasing

CollectionMaterials sent to a MRF

Material Recovery Facility – recyclables are sorted and bundled then sent to reprocesses

Contamination lowers quality of recyclables, lowers sales price.

Reprocessing Paper

ReprocessingPaper – fibers shorten (losing strength) with each reprocess

ReprocessingAluminum and Glass – can be recycled without reducing quality Recycling aluminum saves 95% of energy compared to virgin materials

Recycling glass saves 50% of energy

ReprocessingPlastic - # indicates polymer type

ReprocessingYard waste – leaves, grass, small branches =

compost/mulch!

City of HoustonAs of April 5, 2010 NO yard waste can be put

in trashBuy biodegradable bags at Walmart, Kroger,

Randall’s Lowe’s Homedepot; bags have city logo.

$7.50/10 bagsTwo trucks come around on trash day, one

for garbage, one for compost.Noncompliance? No pick up

RepurchaseComplete the loop!

Demand for recycled materials is critical to the industry

Preconsumer wastes - collected from factories; production wastes

RepurchasePostconsumer – collected at a MRF

Check for understandingWhat do the three arrows in the recycling symbol stand

for?Describe the tradeoff between intrinsic and extrinsic

motivation.What are three benefits of recycling?Of the three R’s, which is the best for the environment, and

why?What is the difference between renewable and recyclable?

Now what do you think?

One bin for all!If you had the deciding vote on whether to go forward with this, what questions would you need answered?

What parts of the standard recycling system are going to be dramatically changed?

How might the new plan change recycling rates?

How might the new plan change citizens’ attitudes about consumption?

Don’t confuse them!The Three R’s = the

hierarchy of waste managementReduceReuseRecycle
