Last week, I asked several environmental groups for feedback on the city’s One Bin For All proposal. I said I would follow up on that with the city. I have their response here, but before I get to it I want to report that I got some further feedback from David Weinberg of the Texas League of Conservation Voters:
TLCV has revised our position on this issue. We have taken no position on Houston’s “One Bin For All” project. We are not deferring to any other organization on the merits of this project. The board of directors is evaluating the project and we will take a public position at a later date.
With that out of the way, here is what the city has to say about the One Bin project.
One Bin for All
By Laura Spanjian, Sustainability Director, City of Houston
The City of Houston is very proud to have won the Bloomberg Philanthropies Mayors Challenge and Fan Favorite contest for One Bin for All. Houston won $1 million for our idea (one of 5 winners out of 305 cities), after working through a challenging and thorough vetting process by Bloomberg Philanthropies.
The City of Houston is excited to work on this game changing technology and make it successful for all Houstonians.
Houston is shaking up the status quo in so many areas:
- Houston a bike friendly city? Yes, with our voter approved $100 million Bayou Greenway and almost $2 million expansion of Bike Share.
- Houston a city that couples historic preservation with sustainability? Yes, the renovated historic Julia Ideson Building and Houston Permitting Center are both LEED Gold.
- Houston a cutting edge forensics hub? Yes, the City is leading the nation in creation of an independently managed Forensic Science Center.
- Houston a city with a growing public transportation system? Yes, we are currently investing more than $4.1 billion to expand the current 7.5 mile urban light‐rail system toa 39‐mile system.
- Houston a recycling leader? Yes, with the potential of One Bin for All, we can transform how people think about trash, making “trash” extinct.
These initiativesare transforming our City. As Mayor Annise Parker has said, “If you can dream it, you can achieve it here.”
The best part of exploring a new idea is to work with people to try to make it happen. There is so much opportunity to work towards something that could have huge positive benefits for Houston, the region and the nation. We appreciate the large positive response we have received in support of this idea, as well as the 15k people who voted for One Bin for All as their favorite idea. We also appreciate the questions and suggestions we have received about the idea, and look forward to continuing our many dialogues and a robust public process as we begin a competitive process to solicit a partner to work with the City. There are many process steps to be undertaken before anything is finally decided. Our Advisory Committee will also be launching soon to provide expert advice as we continue our work.
One Bin’s powerful metaphor is that everything is a resource and everything can be repurposed.
This innovation is in some ways a natural progression for the recycling industry. When recycling first started, it began for a single commodity and then it changed and more commodities were deemed to have value beyond their original use. This change caused these materials to have to be separated (plastics from aluminum from paper). Then, technology advanced again and could handle all recyclables commingled. The waste/recycling industry is constantly figuring out new and different ways that additional materials can be put into this “single-stream” recycling bin. Now, we believe technology has advanced again and is ready to address full commingling and the bulk of the remainder of the waste stream. Thus, the cycle continues its natural progression from dual-stream to single-stream to One Bin.
Unfortunately, what is not very well known is that recycling rates are still very low in the US. According to EPA estimates, after 40 years of recycling education cities only effectively recycle about 30 percent of their trash.The traditional sorting approach to recycling produces low rates of recycling and generally leads to multiple bins, multiple routes, increased operating costs and increased greenhouse gas emissions (GHGs). We believe it’s worth our effort to try to find a better way to address resource recovery. And in the process, we will educate residents about the value all materials have. The concept of trash will be extinct and replaced by an understanding that all discarded material has value and can be recycled or repurposed. Nothing will be “thrown away” any longer.
Will the technology work to achieve high waste diversion?
Many of the individual components contemplated to be deployed have long been used in the waste, mining, food or refining industries. Currently, no facility integrates all of the technologies, processes and systems in the manner envisioned for One Bin for All—but, that’s the innovation. One Bin for All will expand on successful projects in California, Canada, Greece, Germany and England. City staff members have visited several of these facilities, and have seen that residential commingled materials can be processed into valuable resources.
Houston will have a robust and transparent competitive RFQ process and rely on an RFQ Review Committee, leveraging its technical and financial expertise to evaluate critical components of the RFQ responses. To enhance implementation and scalability, an Advisory Committee will provide guidance and recommendations to the City regarding technology evaluations, partnerships, education and outreach.
During negotiations, the City will work to include guarantees for equipment uptime performance and diversion rate and will require escrow funds to compensate the City if there is a breach of contract or default.
Plus, Houston will continue its expansion of its current single-stream recycling program until
One Bin for All is fully implemented. The recycling bins will be used as the One Bin, reinforcing the idea that trash is extinct and all discarded materials have value.
Can the facility be financed?
Raising capital and providing a location lies with the successful proposer. However, Houston can guarantee the city’s residential waste stream and a per ton processing fee for a long-term period, thus providing investors with the assurance they require as well as a reasonable rate of return. Houston can also cultivate commercial and regional partnerships to broaden the reach of the program. Houston will not proceed with a technology that requires the City to pay additional costs than what it is currently paying. The program will be designed to save costs, and by treating all trash as assets with value, generate revenue to the City.
What are the environmental benefits?
As Houston is able to recover and recycle more material from its waste stream, the City will have a reduction in GHGs. The principal source of the reduction will come from diverting organic material (primarily food) away from the landfill, because its decomposition releases methane. Methane is estimated by EPA to be 21 times more potent, in terms of its ability to warm the earth, than the more common carbon dioxide.
According to EPA’s Waste Reduction Model, by diverting 75% of the mixed municipal solid waste to reuse/recycling and composting processes, Houston will reduce roughly 3.72 metric tons of carbon equivalent per ton of MSW diverted.
Houston has been designated a non-attainment area for ozone, a criteria pollutant under the Clean Air Act. One Bin for All will allow solid waste collection routes to be optimized resulting in the removal of the equivalent of 5,000 vehicles off the road each year. The associated emissions reductions in ozone precursors (nitrous oxide and volatile organic compounds) will benefit Houston in its ongoing efforts to achieve attainment status. The City will buy and maintain fewer trucks and residential bins, and will have fewer truck routes to develop, manage, and operate. The current system requires two entirely separate truck routes, crews and equipment (in addition to yard waste and heavy trash pick-up, which the new program might also be able to address). The volume of recyclables in the dual and single-stream is fairly consistently less than a bin full. The One Bin for All proposal lets that inefficient volume of material join the routine weekly stop at the residence to be more efficient, removing VMT and the related emissions.
Beyond these localized effects on air quality, One Bin for All will provide regional and global benefits because reclaimed material will replace virgin raw materials for manufacturing. Using reclaimed material as feedstock reduces or eliminates the energy used in extraction and manufacture of new products.
Why is the One Bin for All process different than a “dirty” materials recovery facility (MRF)?
This innovation is a highly adaptable series of technologies and process innovations. It is unique in that it will process unsorted curbside residential waste, treating all materials as recyclables or valuable assets.
Remove contamination: This innovation will remove 2-inch minus (very small) material early in the sorting process to minimize contamination.
New Design: The innovation has an optimized design which will allow it to be capable of mining all conventional recyclable commodities (paper, plastics, ferrous metals, non-ferrous metals and glass), while producing compost or carbon neutral fuel streams from the remaining low-value wet and dry organics.
Technology: The innovation will utilize only field tested and proven components (ballistic shredders creating 3-D chunks, optical scanners, density separaters, eddy currents, etc.), arranged in a unique order to maximize system productivity and guarantee uptime and high diversion rates without a thermal element.
Organics: The innovation will divert virtually all organics from landfill disposal, turning them into compost or methane (via anaerobic digesters).
Highly specialized sorting: The innovation will separate inbound residential waste into as many as twenty highly concentrated material streams. Separated food and green waste will be further processed with a highly productive, yet passive, biological process to produce large quantities of bio-methane, compost, which is virtually weed seed and pathogen free, and a concentrated, natural, nutrient rich fertilizer. The clean bio-methane will be used to produce electricity, bio-diesel or natural gas through licensed technologies. Lower value, dry organics (wood and textiles) could provide a consistent feedstock ideal for processing using catalytic conversion to drop-in fuels (gasoline and diesel).
Some responses from civic, environmental, waste and industry leaders:
- Michael R. Bloomberg, New York City Mayor and philanthropist, has said, “Recycling has often been treated as an individual responsibility, like paying taxes. But Mayor Parker’s innovative One Bin for All idea turns that notion on its head. Achieving a 75% recycling recovery rate in Houston would represent a huge leap forward in urban sustainability practices.”
- Brian Yeoman, City Director Houston, C40 Cities Climate Leadership Group, says, “The processing technology for Houston’s proposed One Bin for All system is an innovative new integration of improved existing technologies. However, such integration has not been implemented commercially in the United States and only partially in Europe. The City of Houston should continue to follow strict due diligence as it works toward implementation of this alternative to traditional recycling. Special attention should be put forth when drafting the performance requirements, fee structuring, revenue sharing and GHG emissions accounting. C40 believes that there is significant merit in the City of Houston pursuing further and deeper due diligence for this game-changing system. The benefits to the national and international waste industry could be tremendous.”
- Elena Craft of Environmental Defense Fund has said: “I think the One Bin proposal is an interesting and innovative approach to the issue. The City of Houston needed to take a proactive step to deal with its low recycling rate. This proposal beat out many others from other cities to win the Bloomberg Philanthropies grant, and I would like to see it succeed. I believe the concerns that have been raised by others can be addressed.”
- Drew Sones, former director of the Bureau of Sanitation for the City of Los Angeles, has said new sorting technology is already working and that if he were director today, he would use Houston’s approach. “People don’t recycle everything or don’t recycle at all and don’t participate.”
- Alan Del Paggio of CRI Catalyst Company, a Houston subsidiary of Shell, is now turning biomass into gasoline and diesel. “We’re well on our way to demonstrate to the world that this is not just wishful thinking but, in fact, this is a technical reality and an economic reality.”
Other groups supporting our work to move this forward and continue due diligence include: Rocky Mountain Institute; William McDonough + Partners; Houston-Galveston Area Council; Houston Advanced Research Center; University of Houston; Keep Houston Beautiful; Air Alliance Houston; the Greater Houston Partnership; and the Johnson Space Center/NASA.
Republic Services, a waste industry giant, has partnered with Bulk Handling Systems and the City of San Jose to operate a facility that takes all commingled commercial dry waste, using a process similar to what Houston is proposing. And Lancaster, CA, is also considering a one bin type solution. The Lancaster City Council approved a plan to move this idea forward. Overall, companies are very interested in working with the City to try to implement our idea or are interested in learning more. And as reported in Resource Recycling, other waste industry leaders such as Waste Management are neutral. Large recyclers such as the Newark Group would take material from a commingled source if it met their criteria.
Our vision is to obtain the highest possible diversion rates, greatest reductions in greenhouse gas emissions, improved air quality, reduced operations costs, increased revenue and easiest to use program for residents. Let’s work together on what could be an innovation that helps all cities achieve their recycling rates and diversion goals.
Together we can accomplish anything if we work cooperatively, keep an open mind and support new ideas that are trying to do something better, if different. Change is hard, but together we can achieve great things.
That answered a lot of my questions about this project. I hope it answered yours. My thanks to Laura Spanjian for all the information.
