What began as a radical Danish commune inspired by Mao has grown into a multinational clothing-recycling operation accused of cult-like control, diverting aid funds, and exploiting vulnerable children—while its bins still stand in neighborhoods across America.
In parking lots from the fog-shrouded hills of the San Francisco Bay Area to the strip malls of suburban New York and the heartland of the Midwest, the bins stand sentinel. Bright yellow ones bear the logo of Planet Aid, promising to turn your old T-shirts and jeans into aid for farmers in Malawi or teachers in Mozambique. Green-and-white “TreeMachines” from USAgain promise trees planted for every full bin. They are convenient, eco-friendly, and seemingly benevolent—drop off your unwanted clothes, and you help the planet while supporting noble causes.
But behind these unassuming metal boxes lies a story that stretches from the radical communes of 1960s Denmark to the halls of Congress, from international fraud trials to allegations of cult-like control and exploitation of the vulnerable. It is the story of Tvind, or the Teachers Group, a secretive organization founded by Mogens Amdi Petersen that has been accused by defectors, investigators, and courts of transforming utopian ideals into a global network of financial opacity, diverted funds, and broken lives. While the bins continue to collect donations in neighborhoods near you, the full history reveals a cautionary tale of how charisma, ideology, and complexity can mask darker realities.
This investigative profile draws on Danish court records, defector testimonies, U.S. government documents, congressional correspondence, and decades of journalism to unravel the threads. It is a story of revolution that became routine commerce, of schools that became revenue streams, and of a network that adapted, endured, and persists.
The Charismatic Revolutionary: Mogens Amdi Petersen and the Birth of Tvind
Mogens Amdi Petersen was born in 1939 in the border town of Tønder, Denmark, the son of a teacher. In the turbulent 1960s, as anti-nuclear protests swept Europe and the counterculture blossomed, a small group of young idealists in Odense formed a commune. They discussed poetry, politics, and the possibility of a better world. Petersen, tall and thin with shoulder-length hair, joined them. His oratory skills quickly set him apart.
Former members recall how Petersen discovered his power. “He realized he was able to impress people very much,” said early follower Walther Juul Hansen. “He noticed that he was able to make a fantastic influence over people.” In 1967, the group bought a bus and embarked on a journey that would define their path. They traveled through Europe, Africa, and Asia. In Hong Kong, Petersen immersed himself in Mao Zedong’s writings. He began to see their travels not as mere adventure but as a modern equivalent of the Chinese Communists’ Long March—a heroic struggle that would forge a dedicated vanguard.
Petersen wrote letters to Mao and Fidel Castro, positioning himself and his followers as equals in the global revolutionary struggle. By 1970, he formalized the inner circle as the Teachers Group (Lærergruppen), gathering around 40 committed disciples. The name reflected their ambition: to train educators who would transform society from the ground up.
The founding ideology blended several powerful currents of the era. It was anti-imperialist, drawing inspiration from struggles in the Global South. It was environmentalist, rejecting nuclear power and fossil fuels in favor of self-sufficiency. It was collectivist, emphasizing the “common economy” where personal assets were pooled for the greater good. And it was educational, rooted in Denmark’s folk high school tradition but radicalized into tools for social change.
In 1972, the group purchased land at Tvind farm in West Jutland, near the North Sea. There they built schools and, most famously, Tvindkraft—the world’s largest electricity-producing wind turbine at the time. Built by volunteers, teachers, and students in the mid-1970s, it became an icon of grassroots renewable energy.
The turbine still stands today, a testament to early idealism, and helped inspire Denmark’s wind power industry.
Tvindkraft – the oldest operating wind turbine in the world
Petersen demanded extraordinary sacrifice.
“They promise each other to work together for the rest of their life,” recalled Carsten Ringsmose. “And they say they have common economy, common tasks. It means common work time. It means everybody gives up even the smallest bit of their private life.”
New members took oaths of loyalty. The group lived communally, ate together, and submitted major life decisions to the collective—or to Petersen’s inner circle.
Early projects focused on “traveling folk high schools” that sent volunteers to Africa and elsewhere for hands-on development work. In 1977, Humana People to People was established as the international arm. Clothing collections began, initially presented as donations for the poor but quickly becoming a commercial operation selling textiles in bulk.
What began as a small radical commune was evolving into something larger: a network spanning education, aid, and eventually business. Petersen, however, began to withdraw from public view around 1977 as media scrutiny grew. He would remain a shadowy, almost mythic figure for decades.
A 1995 letter provides a blueprint for secrecy and control
By the 1990s, the organization had grown into a complex web of schools, aid projects, and commercial ventures. Public funding, clothing sales, and grants provided substantial revenue. But maintaining control and shielding assets from taxes and authorities required strategy.
A pivotal document—a 1995 internal letter from Petersen to Teachers Group members—reveals the thinking. Seized during Danish police raids and cited in court proceedings and investigations, it outlines how to structure finances:
“The funds are placed so that at any time they are available to us, that they are never available to others, that they are protected from theft, taxation, and prying by unauthorised persons, that the joint ownership is ensured.”
Petersen advocated “twisted paths” for money movement—layered offshore entities in places like the Cayman Islands and Switzerland, salary kickbacks from aid workers in Africa, inter-entity “expenses,” and trusts that kept assets accessible only to insiders. The goal was protection and control: funds available for the group’s purposes while opaque to outsiders.
This letter became central evidence in later fraud cases. It demonstrated not naive communalism but deliberate engineering of financial secrecy. Prosecutors argued it showed intent to divert charitable resources while maintaining the facade of humanitarian work. Defectors described it as the moment the idealistic “common economy” was weaponized into a tool for elite preservation.
The strategy proved effective. The network expanded globally, with clothing bin operations in Europe and the United States generating tens of millions annually. Aid projects in Africa received government grants. Yet questions about where the money ultimately flowed persisted.
The Small Schools: Exploitation of the Most Vulnerable
Among the most harrowing chapters in Tvind’s history are the “Small Schools” (De Små Skoler)—residential programs for troubled youth. Launched in the late 1970s and 1980s in Denmark and the UK, they targeted runaways, children from abusive homes, orphans, immigrants, and those struggling with addiction or behavioral issues. Municipalities paid high fees—sometimes hundreds of pounds or kroner per week per child—for what was marketed as specialized, caring education.
In reality, according to defectors, former pupils, and official inquiries, many of these programs became sites of exploitation.
In the UK, the Red House school near Buxton operated from 1984 to 1998. Dozens of former pupils later alleged physical abuse, sexual abuse, neglect, and harsh discipline. Photographic evidence circulated. A former Tvind head teacher described the English Small Schools as “money machines,” alleging funds were extracted and funneled to support leaders’ lifestyles rather than the children’s welfare.
The UK Charity Commission’s 1997 investigation exposed financial irregularities and poor practices. The schools were closed. One former student successfully sued his local authority for placing him in such an environment. Multiple complaints of abuse surfaced, painting a picture of vulnerable children isolated from families and subjected to controlling conditions.
In Denmark, similar patterns emerged. Small, intimate units received public funding but allegedly delivered substandard care. Funds were reportedly diverted through the broader network. Defectors described psychological manipulation—indoctrination into group ideology, pressure to conform, and isolation that made escape difficult.
The human cost was profound. Survivors reported long-term trauma, trust issues, and difficulty reintegrating into society. The programs exemplified critics’ claims that Tvind exploited public resources and vulnerable populations while projecting an image of progressive education.
Defectors speak of psychological control and shattered lives
The most intimate insights come from those who left. Their accounts, compiled in Frede Farmand’s 2003 book Mesteren fra Tvind and later investigations, describe a system of psychological control that began with idealism and ended in personal devastation.
Steen Thomsen joined in 1977 and rose through the ranks before departing in 1998. In a letter to Danish education authorities, he wrote: “What I for so many years regarded as a peacemaking organisation, working for the oppressed and poor, has turned out to be a cult.” He described initial excitement at being part of world-changing work giving way to authoritarian control, financial opacity, and a sense of betrayal.
Early commune members like Carsten Ringsmose, Walther Juul Hansen, and Eva Kock Sørensen recounted Petersen’s growing charisma.
Hansen described revolutionary fantasies in which Petersen equated himself with Mao and Castro. They spoke of demands for total surrender—finances, relationships, even the right to start a family—pooled into the “common economy.” Upon leaving, many faced broken families, financial loss, and profound regret over years sacrificed.
Volunteer programs through the DRH Movement and IICD (later One World Center) drew idealistic young people with promises of training for aid work. In practice, many reported paying tuition only to perform unpaid labor—collecting and sorting clothes for bins, street fundraising—with minimal actual training or meaningful aid experience. Conditions were often substandard; dissent met with bullying or isolation.
Exit was difficult. The group’s culture framed leaving as selfish failure or betrayal. Some defectors reported shunning or fear of repercussions. The psychological toll was heavy: identity crises, depression, financial ruin, and difficulty trusting institutions or relationships afterward. Many described years of recovery, comparing it to escaping a high-control group.
These accounts humanize the broader allegations. Behind the bins and grants were real people whose lives were reshaped—sometimes shattered—by the organization’s demands.
Communism crossing the Atlantic: Cult’s operations in the United States exploit government grants
Tvind’s reach extended to the United States in the 1990s. Planet Aid, founded in 1997 and headquartered in Maryland, placed yellow donation bins across dozens of states. It collected used clothing and shoes, sold them in bulk, and claimed proceeds supported development projects in Africa and elsewhere through Humana People to People affiliates. Leaders including co-founder Mikael Norling and CEO Ester Neltrup had documented ties to the Teachers Group.
USAgain, a for-profit company, operated green bins and later solar-powered drop spots, with some executives acknowledging Teachers Group membership. Gaia Movement USA and Recycle for Change (formerly Campus California) followed similar models.
These operations generated substantial revenue. Planet Aid alone reported earning tens of millions from textile sales in peak years. Bins became flashpoints in local “clothing bin wars”—zoning disputes, complaints about litter and competition with traditional charities like Goodwill. Planet Aid successfully challenged some municipal restrictions on First Amendment grounds.
More controversially, Planet Aid received significant U.S. government funding. Over more than a decade, the USDA Foreign Agricultural Service allocated over $133 million in grants for projects in Malawi and Mozambique—Farmers’ Clubs to improve agriculture, school feeding programs, teacher training, and health education. These were often implemented through local Humana/DAPP partners.
Investigations by Reveal/CIR and NBC in 2016 raised serious questions. Field reporting in Malawi described minimal actual aid reaching communities—examples included a single goat and pig that died, pre-existing trees credited as new plantings, and “demonstration plots” that were Potemkin villages staged for auditors. Whistleblowers alleged kickbacks, fabricated invoices, and pressure to overstate results. Funds allegedly flowed through layered entities back toward the Teachers Group network.
USDA maintained that its audits and site visits found no major issues at the time, though internal concerns existed. The agency referred allegations to its Inspector General. Planet Aid denied wrongdoing and emphasized positive outcomes and compliance.
The bins and grants created a paradox: visible, convenient recycling infrastructure funded in part by taxpayer dollars, yet shadowed by persistent questions about ultimate beneficiaries and impact.
Legal battles, congressional scrutiny, and enduring questions
Danish authorities launched major investigations in the early 2000s. Raids in 2001 seized computers and documents. Petersen was arrested in the U.S. in 2002 and extradited. The main fraud trial concerning the Humanitarian Fund began in 2003.
In 2006, a district court acquitted most defendants, including Petersen. Sten Byrner received a suspended sentence. Prosecutors appealed. In 2009, Poul Jørgensen was convicted and sentenced to 2.5 years. In 2013, Petersen and four others were convicted in absentia and sentenced to one year each. They remain fugitives, believed to be in Mexico; Interpol warrants are active.
A separate 1999 Supreme Court ruling struck down a special law targeting Tvind school funding as unconstitutional—the first time the Court had invalidated legislation on such grounds.
In the U.S., the 2016 Reveal reporting prompted Rep. Betty McCollum (D-MN) to write to the GAO and USDA Inspector General on August 17, 2016, urging comprehensive investigations into Planet Aid contracts and potential misuse of funds. Investigations were launched, including by USDA OIG and the Department of Justice. FOIA documents later confirmed coordination with international partners. However, no major public final reports with detailed findings of widespread fraud leading to contract terminations were prominently released; existing grants largely continued under procurement rules.
Planet Aid sued Reveal for libel; the case involved complex anti-SLAPP motions and ultimately settled with Planet Aid paying significant legal fees.
The network adapted. Operations continued. Charity watchdogs gave low ratings to some entities for efficiency and transparency. Yet bins remained, grants flowed in some forms, and the organization maintained its humanitarian and environmental messaging.
A Neighborhood Near You—and the Lessons Beyond
Today, the bins persist. In California, New York, Illinois, and beyond, residents encounter Planet Aid yellow boxes or USAgain green ones. They offer a simple, tangible way to recycle textiles amid growing awareness of fast fashion’s environmental toll. Planet Aid highlights community drives, solar centers, and reported impacts in partner countries. USAgain emphasizes tree planting and reuse statistics.
Yet the full history raises uncomfortable questions. How much of the revenue truly reaches intended beneficiaries versus sustaining the network’s infrastructure and leadership? What accountability exists when operations span multiple countries, layered entities, and decades of shifting legal scrutiny? How do communities balance convenient recycling infrastructure against concerns about the organizations behind it?
The bins in your neighborhood are not inherently sinister. They represent one model of textile reuse in a world drowning in discarded clothing. But understanding their origins—the communist-inspired Danish collective that became a global operation accused of cult-like control and financial engineering—transforms a mundane act of donation into a window onto power, idealism, betrayal, and resilience.
Mogens Amdi Petersen, now in his mid-80s and a fugitive, built something that outlasted him. The Teachers Group’s influence, through affiliated entities, still touches everyday American life. Whether that influence is primarily environmental good, commercial enterprise, or something more complex remains a matter of ongoing debate and scrutiny.
The next time you see a yellow or green bin, pause. The story behind it is longer, stranger, and more consequential than the simple act of dropping off an old sweater suggests. It is a story of revolution that became routine, of dreams that became dollars, and of a network that, for better or worse, operates in a neighborhood near you.
