When China’s plastic ban took impact in January 2018, recycling facilities in Boise, Idaho, have been compelled to chop again on the plastics they might settle for.
Plastics marked with plastic resin codes 3 through 7 have been now not accepted in curbside recycling carts, resulting in frustration amongst Boise residents. “Our group is deeply dedicated to sustainability, so sending these plastics to the landfill was the final possibility for us,” defined former Boise Mayor Dave Bieter in a press release.
Fortunately for Boise residents, town gained a $50,000 grant to ascertain a neighborhood Hefty trash bag assortment program that launched in April 2018. The authentic EnergyBag® Program, initiated in 2014, aimed to divert non-recyclable plastics from landfills by changing them into power sources. However, this method faced environmental concerns, significantly concerning the incineration of plastics, which might launch pollution and greenhouse gases.
In response to those issues, Hefty rebranded the program as Hefty ReNew™ in March 2023, emphasizing extra sustainable practices. The ReNew™ Program focuses on superior recycling applied sciences, such the controversial process known as pyrolysis and typically known as “superior chemical recycling,” to transform hard-to-recycle plastics into priceless sources like artificial diesel gasoline, thereby lowering reliance on fossil fuels and minimizing environmental influence. Critics argue that pyrolysis can emit pollution, together with carcinogens like benzene and dioxins, and should produce extra greenhouse gases than conventional plastic manufacturing strategies. Additionally, some research counsel that pyrolysis usually depends closely on fossil fuels, with a good portion of the output containing minimal recycled materials.
Hefty commissioned an independent life cycle assessment performed in 2022 to guage the environmental impacts of the Hefty ReNew™ Program, reporting that the research discovered that utilizing program supplies as gasoline in cement kilns resulted in larger environmental advantages throughout varied components in comparison with landfilling.
What Is the Hefty ReNew™ Program?
The EnergyBag program permits collaborating households to position a variety of plastic products — resembling meals pouches, plastic utensils, plastic grocery luggage, straws, and candy wrappers — right into a particular orange bag. When full, the orange bag could be tied up and positioned within the curbside recycling bin. From there, it makes its strategy to the native recycling facility the place it’s presorted, baled, and delivered to a neighborhood recycling companion.
In Boise, supplies collected for the Hefty ReNew program are despatched to a Firstar Inc.-owned pyrolysis facility that converts plastic waste right into a power and recycled composite lumber merchandise. The course of retains plastics out of the landfills. It additionally reduces the quantity of fossil gasoline that should be extracted from the bottom and retains sources in use — ostensibly contributing to a extra circular economy.
In an 2018 interview with KTVB, Colin Hickman, the communications supervisor for the City of Boise Public Works Department, reported this system’s success in its first two months. “We’ve collected about 54,000 kilos of non-recyclable plastic. You take into consideration how light-weight plastic is, that’s an incredible quantity of fabric. At its most elementary stage, that’s 54,000 kilos of fabric that may’ve been buried within the landfill eternally and now could be going to be given new life and be beneficially reused.”
Where Is the Program Running?
Besides Boise, the Hefty ReNew™ Program is lively in northern Chicago, Cincinnati, Dayton and Central Ohio, Atlanta, Omaha and Lincoln, Nebraska, Tucson, Arizona, and Chattanooga, Tennessee. As with Boise and Omaha, Cobb County’s plastics will make their strategy to an authorised finish market. However, Omaha’s program has been lambasted by critics as dangerous to the setting; the plastics collected in Omaha finish their life cycle incinerated, not transformed into gasoline.
In 2018, Earth911 requested this system’s sponsor, Dow, and the incinerator operator’s response to the criticism.
“Using onerous to recycle plastics as gasoline retains these supplies out of landfills and acts as a stepping stone till pyrolysis applied sciences and the associated infrastructure are additional developed and in place at a viable scale,” stated Jeff Wooster, Global Sustainability director at Dow Packaging and Specialty Plastics, which sponsors the Hefty ReNew™ program, in response to critics of the Omaha incineration program. “Ultimately, every step helps deliver us nearer to elevated chemical recycling that may allow the manufacturing of plastics from recycled chemical compounds.”
“Even although plastic incineration is being questioned,” stated Dale Gubbels, president and CEO of supplies restoration facility Firstar Inc., which processes EnergyBag supplies, “these in any other case onerous to recycle plastics displace the necessity for non-renewable gasoline sources, resembling coal and coke, within the manufacture of cement. Interim end-markets that use collected plastics as fuels, like cement kilns, offset the necessity for virgin gasoline and prolong the usefulness of waste plastics.”

By shifting to the Hefty ReNew™ Program, Hefty goals to handle earlier environmental points and contribute to a extra round economic system, successfully diverting hard-to-recycle plastics from landfills and changing them into priceless sources. It claims to have diverted greater than 3,000 tons of waste for the reason that program started nearly a decade in the past. However, the controversies surrounding pyrolysis spotlight the significance of steady analysis and enchancment of recycling applied sciences to make sure they supply real environmental advantages.
Although recycling isn’t one of the best factor we will do for the setting — ideally, we’d stop waste creation within the first place — it’s nonetheless preferable to therapy or disposal. Until resembling time as single-use plastics are banned or customers cease shopping for them, the Hefty ReNew™ program is a step that communities can take to maintain plastics out of landfills and oceans.
