Welcome!Please get out objectives #1-8 for a stamp!
By adding new learnings in a different pen, you’ll be reviewing for the quiz.
Please read the board!
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

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
