Mow Down Pollution: 2019 Lawn Mower Exchange
Who Says Old Buildings Can’t be Energy Efficient?
The Golden History Museum in partnership with the Community Sustainability Advisory Board have installed new mini-splits in two cabins at the Golden history park. The museum has been working hard to find an efficient way to heat and cool the 1800’s buildings. Mini-splits are heating and cooling systems that allow you to control the temperatures in individual rooms or spaces.
Mini-splits provide a high-efficiency alternative to conventional window-type or wall-type HVAC equipment. In addition to offering energy efficiency, ductless mini-splits can be installed with minimal modifications to indoor spaces. They can be especially useful in sturdy constructions such as pre-war apartment buildings, where the installation of ducted HVAC systems is especially challenging.
Council Approves Sustainability Goals
After an extensive community input process, on Feb. 14, 2018, City Council unanimously passed a resolution to formally revise Golden’s existing sustainability goals and set new targets related to energy, water and waste. The Community Sustainability Advisory Board (CSAB) worked diligently to renew the City’s commitment to sustainability by creating new sustainability goals.
“It’s a special time for our sustainability efforts in Golden,” said Mayor Marjorie Sloan. “Golden was an early adopter of sustainability goals, and it has been exciting to see how sophisticated we have become in terms of what can be accomplished and the time it will take to achieve of our goals.”
Golden intends to meet the following Sustainability Goals:
- Renewables: To achieve 100% renewable energy for electricity by 2030 and 100% renewable for heating by 2050. To align Greenhouse Gas Emission reductions with the Paris Accord by 2050.
- Efficiency: To reduce consumption of electricity by 15% by 2030 and reduce consumption of natural gas by 15% by 2030.
- Transportation: To achieve 20% fossil fuel-free transportation sector by 2030 and 100% fossil fuel-free transportation sector by 2050.
- To reduce total landfill contribution by 40% by 2030.
- Recycle 80% of recyclables by 2030.
- Compost 80% of compostables by 2030.
- Reduce total trash by 20% by 2030.
- Strive for zero waste in municipal operations by 2030.
- Responsible Use: To reduce per capita total water use in Golden by at least 15% by 2030.
- Drought Planning: To develop a resiliency plan by 2020 to prepare for a time where Golden’s and Colorado’s climate may be substantially warmer and drier than it is today.
- Resource Recovery: To develop and implement a plan by 2020 where Golden’s surplus water is used effectively not only to manage the cost of water and sewer services, but to enhance the environment in Golden and elsewhere in our watershed. Additionally, to recover resources from the City’s wastewater by 2030.
“It is a lot of hard work to set and revise goals. We often set goals and they are left unrevised until we achieve them or until time expires,” said Laura Weinberg, City Councilor Ward 4. “I think it is really exciting to look at what we have already accomplished and keep moving that goal line forward to set even more ambitious goals for the City.”
“As Council acknowledged, these goals aren’t just a pipe dream,” said Ken Jacobs, CSAB Chair. “We fully expect them to be realized. It will take the combined efforts of all segments of the Golden community, from the School of Mines to mom and pop retailers, from Jeffco government and schools to big businesses like CoorsTek. It will take all of us working together to succeed in becoming a truly sustainable community. Luckily, from all of the input we’ve received, it seems as if the community is more than up to the task.”
The next step is to evaluate community ideas and potential projects. CSAB will quantify the costs and benefits of various proposals and create a strategic plan. For more information about the City’s Sustainability Goals, visit the Sustainability Initiative page.
Golden Recycling Provider Responds to China’s Recycling Restrictions in a Big Way
For many years, recycling sorting facilities in the U.S. (also called “MeRFs”, or Material Recovery Facilities) have shipped certain plastics to China where any contamination (trash, non-plastics) that may have been missed in the U.S. sorting process must be discarded. Last year, China became stricter with how much contamination would be allowed in the shipments. Business-savvy MeRFs invest in innovative technologies to ensure a lower level of contamination and therefore a higher market price for the materials. Other MeRFs who cannot effectively prevent contamination are forced to sell to processors inside the U.S. This surplus of plastics within the U.S. has a temporary, but negative affect on commodities prices.
Because China is the largest importer of recyclable materials, Golden’s recycling provider, Alpine Waste & Recycling, has made aggressive changes to their operations. During a recent tour Alpine Waste & Recycling’s MeRF in Denver, Vice President Brent Hildebrand explained the steps Alpine has taken to respond to China’s new rules. “The restrictions are very tough to meet. We have slowed the processing system down and brought in extra workers to more thoroughly vet the materials going through to look for contaminants.”
Alpine’s continued investment in innovative technologies has also helped. A new robot, nicknamed Clark, uses artificial intelligence to pick up and sort recyclables at a rate much faster than humans. Workers help it recognize new materials so it is continually learning and it even shares its new information with other MeRFs around the country. Elsewhere, an optical sorting machine “sees” different types of materials on the assembly line and uses puffs of air to shoot the materials to an appropriate bin.
The new technologies not only increase efficiency, and reduce contamination, but have also helped Alpine process materials not previously accepted, like block Styrofoam and Starbucks coffee cups (Yes, if your household participates in the City’s waste and recycling collection program or uses Alpine Waste as its hauler, you can now recycle single use coffee cups!).
One way you help keep the stream clean? “Metal objects, such as car parts, oven pans, and tools can cause the sorting system to be down for hours due to damaged equipment,” Hildebrand said. “It’s a really big deal and we need to educate people on what’s acceptable and what is not acceptable in the recycling stream.” Check out the complete list of Alpine’s accepted materials on the City website and spread the word. Together, we can keep the business of recycling in business.
America Recycles Day Resources
Let’s be honest, recycling can get confusing pretty quickly. Here are “recycling decoders” These templates (magnets , bookmarks, flyers) are designed to help make it easy to get stuff recycled right.
- Recycling Decoder (Print Ready Recycling Tip Magnet)
- Recycling Fact Sheet
- “Recycling by Room” Infographic
Nothing can be more daunting to would-be recyclers than trying to figure out what can be recycled, when, where and how. Fortunately, figuring out when, where and how to recycle in your community couldn’t be easier. Check the America Recycles Day recycling locator to get started.
A Firsthand Look at the Where Our Green Waste Goes
Recently, Golden residents were given the opportunity to tour Alpine Waste and Recycling’s Class II Compost Facility in Bennett, CO. As the hauler of the City of Golden’s compost, Alpine processes up to 250 tons of compost a month. This experience provided a firsthand glimpse into the path our food and yard our waste takes once it leaves our homes and businesses.
The process begins with Alpine’s compost route trucks collecting food and yard waste. After a transfer in Denver, the material arrives at the main hot commercial compost site in Bennett. The compost is then placed in mixing machines, which make sure there is a right combination of nitrogen (green materials) and carbon (brown materials) to create the compost. The compost is then placed in approximately a dozen, 400-foot -long “windrows” where it is turned and generates internal heat until it reaches a minimum of 131 degrees. The process takes about ten weeks.
After rigorous testing, the final product of enriched compost is sold to buyers in the landscaping and agricultural industries. King Soopers is one of Alpine’s largest suppliers of compostable material and buyers of finished compost. King Soopers brings their composting effort full circle by sending spoiled produce to Alpine’s compost facility and then purchasing back the finished product and selling it as potting soil in their stores. This summer, look for Kroger brand bagged compost with the “Colorado Proud” logo.
It’s the perfect time to sign up for Golden’s curbside Organic Compost Service. This bi-weekly, year-round service is directly billed to you for $9.45/month. Anyone can participate – sign up for yourself, split the costs with a neighbor, or ask your complex to sign up for a compost dumpster.
