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% Landfilled 34% Recycled 12% Incinerated Houston MSW disposal: 86% Landfilled 14% Recycled 0% Incinerated
Houston’s “One Bin for All” ALL waste in one bin One 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 company Construction to begin next year Could 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 against Mayor and city sustainability coordinator Environmental Defense Fund Clinton Climate Initiative Keep 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
Collection Curbside or Drop off
Collection How do you increase participation? Intrinsic motivation Education Extrinsic motivation Fines Bottle bills Cost differentials Bottle Bill Video and Petition Bottle Bill Video and Petition The Fun Theory--Bottle Bank Arcade The Fun Theory--Bottle Bank Arcade
Collection Materials 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
Reprocessing Paper – fibers shorten (losing strength) with each reprocess
Reprocessing Aluminum and Glass – can be recycled without reducing quality Recycling aluminum saves 95% of energy compared to virgin materials Recycling glass saves 50% of energy
Reprocessing Plastic - # indicates polymer type
Reprocessing Yard waste – leaves, grass, small branches = compost/mulch!
City of Houston As of April 5, 2010 NO yard waste can be put in trash Buy biodegradable bags at Walmart, Kroger, Randall’s Lowe’s Homedepot; bags have city logo. $7.50/10 bags Two trucks come around on trash day, one for garbage, one for compost. Noncompliance? No pick up
Repurchase Complete the loop! Demand for recycled materials is critical to the industry Preconsumer wastes - collected from factories; production wastes
Repurchase Postconsumer – collected at a MRF
Check for understanding What 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 management Reduce Reuse Recycle
