In 2019, MIT’s Setting, Well being, and Security (EHS) Workplace collaborated with a number of analysis labs within the Division of Biology to find out the feasibility of recycling clear lab plastics. Based mostly on early successes with waste isolation and plastics assortment, EHS collaborated with GreenLabs Recycling, an area startup, to take away and recycle lab plastics from campus. It was an enormous success.
In the present day, EHS spearheads the campus Lab Plastics Recycling Program, and its EHS technicians often collect clear lab plastics from 212 MIT labs, transferring them to GreenLabs for recycling. Since its pilot stage, the variety of labs taking part in this system has grown, rising the overall quantity of plastic gathered and recycled. In 2020, EHS collected 170 kilos of plastic waste per week from taking part labs. That elevated to 250 kilos per week in 2021. In 2022, EHS collected a complete of 19,000 kilos, or 280 kilos of plastic per week.
Joanna Buchthal, a analysis assistant with the MIT Media Lab, signifies that, previous to becoming a member of the EHS Lab Plastics Recycling Program, “our laboratory was repeatedly troubled by the substantial quantity of plastic waste we produced and disheartened by our lack of ability to recycle it. We often addressed this subject throughout our group conferences and explored numerous methods to repurpose our waste, but we by no means arrived at a viable resolution.”
The EHS program now gives an answer to labs dealing with comparable challenges with plastics use. After pickup and elimination, the plastics are shredded and offered as free inventory for injection mould product manufacturing. Buchthal says, “My total lab is delighted to recycle our used tip packing containers and rework them into helpful objects for different labs!”
Just lately, GreenLabs introduced EHS with a three-gallon bucket that native producers produced from one hundred pc recycled plastic gathered from MIT labs. No fillers or components have been utilized in its manufacturing.
Conserving it clear
The now-growing EHS service and operation began as a pilot. In June 2019, MIT restricted which lab-generated objects may very well be positioned in single-stream recycling. MIT’s waste distributors have been now not accepting presumably contaminated waste, akin to gloves, pipette tip packing containers, bottles, and different plastic waste sometimes generated in organic analysis labs. The waste distributors would audit MIT’s single-stream recycling and reject objects in the event that they noticed any contamination.
Dealing with these challenges, the EHS coordinator for biology, John Fucillo, and a number of other EHS representatives from the division met with EHS workers to brainstorm potential recycling options. Making certain the decontamination of the plastic and coordinating its elimination in an environment friendly means have been the first challenges for the labs, says Fucillo, who shared his and lab members’ issues concerning the quantity of plastic being thrown away with Mitch Galanek, EHS affiliate director for the Radiation Safety Program. Galanek says, “I instantly acknowledged the frustration expressed by John and different lab contacts as a possibility to collaborate.”
In July 2019, Galanek and a group of EHS technicians started segregating and gathering clear plastic waste from a number of labs throughout the biology division. EHS supplied the labs with assortment containers, and its technicians managed the waste elimination over a four-month interval, which produced a snapshot of the quantity and kind of waste generated. An audit of the waste decided that roughly 80 % of the clear plastic waste generated was empty pipette tip packing containers and conical tube racks.
Based mostly on these information, EHS launched a lab plastics recycling pilot program in November 2019. Labs from the Division of Biology and the Koch Institute for Integrative Most cancers Analysis have been invited to take part by recycling their clear, uncontaminated pipette tip packing containers and conical tube racks. Along with offering these labs with assortment packing containers and plastic liners, EHS additionally developed an online waste collection request tool to submit plastic pickup requests. EHS additionally collected the waste containers as soon as they have been full.
Assistant professor of biology Seychelle Vos joined the pilot program as quickly as she began her lab in fall 2019. Vos shares that “we already use pipette suggestions packing containers that produce minimal waste, and this program permits us to principally recycle any a part of the field apart from suggestions. Pipette packing containers are a major supply of plastic waste. This program helps us to be extra environmentally and local weather pleasant.”
Given the elevated participation in this system, EHS technician Dave Pavone says that plastic pickup is now a “common element of our work schedules.”
Collectively, the EHS technicians, generally generally known as “techs,” handle the pickup of almost 300 plastic assortment containers throughout campus. Normand Desrochers, one of many EHS techs, shares that every morning he plans his pickup route “to get the job completed effectively.” Whereas weekly pickups are a rising a part of their schedules, Desrochers notes that everybody has been “tremendous appreciative in what we do for his or her labs. And what we do makes their job that a lot simpler, with the ability to deal with their analysis.”
Barbara Karampalas, a lab operations supervisor throughout the Division of Organic Engineering, is considered one of many to precise appreciation for this system: “We have now a pretty big lab with 35 researchers, so we generate a whole lot of plastic waste … [and] figuring out what number of tip packing containers we have been utilizing involved me. I actually respect the hassle EHS has made to implement this program to assist us scale back our affect on the surroundings.” This system additionally “makes individuals within the lab extra conscious of the problem of plastic waste and MIT’s dedication to scale back its affect on the surroundings,” says Karampalas.
Wanting forward
MIT labs proceed to enthusiastically embrace the EHS Lab Plastics Recycling Program: 112 college throughout 212 labs are at the moment taking part in this system. Whereas solely empty pipette tip packing containers and conical tube racks are at the moment collected, EHS is exploring which lab plastics may very well be manufactured into merchandise to be used within the labs and repeatedly recycled. Particularly, the EHS Workplace is contemplating whether or not recycled plastic may very well be used to supply secondary containers for gathering hazardous waste and benchtop switch containers used for gathering medical waste. As Seychelle notes, “Most plastics can’t be recycled within the present schemes as a result of their use in laboratory science.”
Says Fucillo, “Our hope is that this program could be expanded to incorporate different merchandise which may very well be recycled from the moist labs.” John MacFarlane, analysis engineer and EHS coordinator for civil and environmental engineering, echoes this sentiment: “With plastic recycling dealing with financial constraints, this effort by the Institute deserves to be promoted and, hopefully, expanded.”
“Having extra alternatives to recycle ’biologically clear’ plastics would assist us have a smaller carbon footprint,” agrees Vos. “We love this program and hope it expands additional!”
