Alison Badgett named director of the Priscilla King Gray Public Service Center
Vice Chancellor for Undergraduate and Graduate Education Ian A. Waitz announced recently that Alison Badgett has been appointed the new associate dean and director of the Priscilla King Gray (PKG) Public Service Center. She succeeds Jill Bassett, who left that role to become chief of staff to Chancellor Melissa Nobles.
“Alison is a thought leader on how to integrate community-engaged learning with systematic change, making her ideally suited to actualize MIT’s mission of educating transformative leaders,” Waitz says. “I have no doubt she will make the PKG Center a model for all of higher ed, given her wealth of experience, finely honed skills, and commitment to social change.”
“I’m excited to help the PKG Center, and broader MIT community, develop a collective vision for public service education that builds on the PKG Center’s strength in social innovation programming, and leverages the Institute’s unique culture of innovation,” Badgett says. “MIT’s institutional commitment to tackling complex societal and environmental challenges, taking responsibility for outcomes and not just inputs, is exceedingly rare. I’m also especially excited to engage STEM majors, who may be less likely to enter the nonprofit or public sector, but who can have a tremendous impact on social and environmental outcomes within the systems they work.”
Badgett has over 20 years of experience leading public policy and nonprofit organizations, particularly those addressing challenging issues like affordable housing and homelessness, criminal justice, and public education. She is the founding principal of a consulting firm, From Charity to Change, which works with nonprofit leaders, educators, and philanthropists to apply systems-change strategies that target the root causes of complex social problems.
Prior to her consulting role, Badgett was executive director of the Petey Greene Program, which recruits and trains 1,000 volunteers annually from 30 universities to tutor justice-impacted students in 50 prisons and reentry programs. In addition, the program educates volunteers on the injustice of our prison system and encourages both volunteers and students to advocate for reforms.
She also served as executive director of Raise Your Hand Texas, an organization that aims to improve education by piloting innovative learning practices. During her tenure, the organization launched a five-year, $10 million initiative to showcase and scale blended learning, and a 10-year, $50 million initiative to improve teacher preparation and the status of teaching.
Before leading Raise Your Hand Texas, Badgett was executive director of several organizations related to housing and homelessness in New York and New Jersey. During that time, she developed a $3.6 million demonstration program to permanently house the chronically homeless, which served as a model for state and national replication. She also served as senior policy advisor to the governor of New Jersey, providing counsel on land use, redevelopment, and housing.
Badgett holds a global executive EdD from the University of Southern California, an MA from Columbia University Teachers College in philosophy and education, and an BA in politics from Princeton University.
Her appointment at the PKG Center is especially timely. Student demand for social impact experiential learning opportunities has increased significantly at MIT in recent years, and the center is expected to play a sizable role in increasing student engagement in social impact work and in helping to integrate social innovation into teaching and research.
At the same time, the Institute has made a commitment to help address complex issues with global impacts, such as climate change, economic inequality, and artificial intelligence. As part of that effort, the Office of Experiential Learning launched the Social Impact Experiential Learning Opportunity initiative last year, which has awarded nearly $1 million to fund hundreds of student opportunities. Projects cater to a broad range of interests and take place around the world — from using new computational methods to understand the role of special-interest-group funding in U.S. public policy to designing and testing a solar-powered, water-vapor condensing chamber in Madagascar.
Badgett, who is currently writing a book on re-imagining civic education at elite private schools, will begin her new role at the PKG Center in July. In the meantime, she is looking forward to bringing her experience to bear at MIT. “While leading public interest organizations was highly rewarding, I recognized that I could have a far greater impact educating future public interest leaders, and that higher education was the place to do it,” she says.

New method aims for more plastic recycling - Technology Org
Arnott’s Group, the maker of the iconic Tim Tam, is exploring ways to use patented research from UNSW to convert solid waste plastic with low energy and minimal cleaning.

UNSW researchers have developed a new low-energy technique to recycle plastic, which could be coming to a Tim Tam package near you.
The process can transform many forms of waste plastic into their respective polymer nanoparticles dispersed in water which can then either be extracted for re-use in preparing new consumer products, or utilised still in the aqueous dispersion in applications such as asphalting and waterproof coatings.
The innovative technique also removes dyes from the original plastic waste, which currently requires separate treatment, thus reducing the time and cost of recycling and expanding the waste source.
Team leads Professor Per Zetterlund and Dr Vipul Agarwal, from the School of Chemical Engineering, are working in collaboration with ‘impact investment’ firm FP Paradigm to further develop and commercialize the technology specifically pertaining to PET (polyethylene terephthalate) recycling. The relevant aspects of the UNSW patent (PET in food and beverage applications) have been licensed to FP Paradigm.
Paco Industries, the R&D subcontractor for FP Paradigm, has recently announced a deal with the Arnott’s Group – makers of Tim Tams and Shapes – to explore the use of this new technology as a more sustainable PET alternative across their range of products.
The UNSW researchers say their new method – which can be used on a wide range of common materials such as bags, bottles made from polyethylene, polypropylene, polystyrene, and PET – has the potential to significantly reduce the degradation of the plastic (polymers) during recycling.
Arnott’s is particularly keen on the fact that the process can isolate PET from other types of waste plastics and has the potential to turn contaminated PET waste back into food-grade PET for the food and beverage industry.
Non-degradation
“Plastics recycling is a massive challenge globally and there are many hurdles to overcome. For example, CSIRO statistics show that 84% of plastic currently used in Australia is sent to landfill and only 13% is recycled,” said Dr Agarwal.
“One of the main issues with the current way of recycling plastics is that it typically requires very high temperatures and therefore considerable amounts of energy and, in many cases, high shear forces during melt extrusion,” said Prof. Zetterlund.
“This can lead to the breakdown of individual polymer chains in the plastic, which is one of the reasons why you cannot recycle an infinite number of times, because each time the process is done the polymer degrades.
“Our method has the potential of causing no mechanical or chemical degradation of the polymer, so we believe it may be possible to recycle the plastic a higher number of times than using existing recycling processes.
“In addition, there is no need for extensive cleaning of the waste plastic before it is recycled. This process also has the potential to separate the polymer from various additives such as dyes, eliminating one of the stages currently required in current recycling processes.
“The other advantages of this new technology are tolerance to mixed plastic waste allowing segregation of different waste plastics during the recycling process, and recycling of chemicals used in the process,” said Dr Agarwal.
In addition to the deal with Arnott’s, Paco has also facilitated an agreement with Sydney-based sustainably-focused coffee company Pablo & Rusty’s to assist with the commercialisation of the UNSW-developed recycled PET.
Arnott’s Group Chief Transformation Officer Simon Lowden said: “This agreement reflects our commitment as a business to go beyond our sustainable commitments and find new technologies – so that the Arnott’s Group can continue to create delicious moments, not just for our consumers, but for our value chain and planet as well.”
According to the CSIRO, Australians used 3.5 million tonnes of plastics in 2018 to 2019, with around 130,000 tonnes leaking into marine environments each year.
By 2050, they estimate that plastic in the oceans will outweigh fish.
CSIRO has calculated that Australia is missing out on an estimated $419m of economic value each year by not recovering all PET and HDPE (high-density polyethylene) materials.
PET is one of the world’s most commonly used plastics, with approximately 10% of all plastics being made from PET, and around a third of that used in global food and beverage packaging.
The primary challenge is the level of contamination in such plastic, making it harder to recycle without being thoroughly cleaned.
Aqueous dispersion
Prof. Zetterlund and Dr Agarwal’s patent covers the specific process that converts waste plastic into an aqueous dispersion of plastic polymer nanoparticles, allowing the very small solid polymer particles to be uniformly distributed in a water-based solution.
The obtained dispersed nanoparticles are not to be confused with microplastics.
In their patented method, different types of waste polymers can be segregated, potentially enabling simultaneous recycling of different types of plastics.
At the next stage, a traditional filtration process can extract the nanoparticles to then produce pellets or powder which can be used to make new plastic materials.
But the UNSW research team, which also includes postdoctoral fellow Dr Mike Dinh and previously Dr Rabiatul Adawiah Mat Noor, say the aqueous solution with the particles remaining dispersed can provide benefits in various other applications, such as the production of asphalt as one example.
Recycled plastic is currently used in asphalt via a melting process whereby it becomes part of the bituminous binder that ‘glues’ together the sand and gravel aggregate.
“Using our process, we can take the aqueous waste plastic dispersion and instead coat the aggregate material before it’s added to make the asphalt, and that can help everything to bind really well. We believe it will improve the strength and durability of the final asphalt,” said Dr Agarwal.
“We also believe that our recycled aqueous waste plastic dispersion has potential use in the production of waterproofing materials and high-strength concrete, following the same principle as asphalt, paints, and insulation coatings.”
