Xinca Villagers Cut Plastic Burning Through Community Cleanups in Guatemala

In Guatemala’s Santa María Xalapán mountains, Indigenous Xinca communities working with the Ecolectivos research project have removed thousands of bags of trash and chosen local strategies to burn less plastic.

Today’s Progress

In the mountain village of El Duraznal near Jalapa, Guatemala, Soila Elizabeth Cruz—known as Betty—pulls plastic bottles and packaging from under a barbed-wire fence and into a garbage bag. Her community organizes cleanups every three to five months. Cruz, a mother of three, was elected promotora, or environmental health leader, after months of workshops run by Ecolectivos, a research collaboration among the University of California, San Francisco (UCSF), Emory University, and Universidad del Valle de Guatemala.

The project is co-led by Lisa Thompson of UCSF and Eri Saikawa of Emory. It works with rural Indigenous Xinca villages in the Santa María Xalapán mountains, where plastic is often burned to dispose of waste or to start and stoke cooking fires. Burning releases toxic chemicals linked to cancer, immune disorders, birth defects, and disruption of hormone and nervous systems.

According to reporting by Liza Gross for Inside Climate News (supported by the Pulitzer Center), workshops helped residents design feasible long-term plans to cut plastic waste and combustion. Strategies included community cleanups and sorting glass, metal, and plastic that can be sold to recycling companies.

Thompson told Inside Climate News that people in eight intervention villages removed more than 4,500 large bags of trash during dozens of cleanups over two years. Even residents of control villages joined at least one cleanup and recycling event. In El Duraznal, Cruz said the workshops motivated neighbors to support one another: “Now we motivate each other to not burn plastic and to reduce.”

Elsewhere, promotora Wendy Hernandez was trained to teach recycling and reuse—turning old items into art instead of tossing them on the ground or into kitchen fires—and visited more than two dozen households each month. Early cleanups drew as many as 200 people; later ones about 50, she said.

Why This Matters

Open burning of plastic is both a waste and a household-energy problem in places with limited collection services. Guatemala has limited capacity to manage waste while imports of household plastic goods have risen sharply; an Inside Climate News review of United Nations trade data found more than 1.2 million tons imported over the past decade.

When communities stop burning plastic, they reduce local emissions of microplastics, dioxins, polycyclic aromatic hydrocarbons, and other pollutants that harm people—especially women and children who cook and tend fires—and nearby ecosystems. Cleanups also remove litter that clogs landscapes and waterways. The immediate, documented benefit is collective action that removes waste and builds local leadership; longer-term health gains from lower exposure remain under study.

Evidence and Context

Ecolectivos is described as the first research project to test, with villages randomly assigned to intervention or control groups, whether planned behavior changes can reduce women’s exposure to plastic-combustion by-products. A 2019 proof-of-concept led with anthropologist Mayari Hengstermann in La Fuente informed later educational materials.

Strengths of the current evidence include a multi-year count of trash bags removed, elected community leaders, household outreach, and reported shifts in motivation away from burning. Limits are clear: published snippets do not yet detail final measured drops in personal exposure or health endpoints; participation in cleanups has varied over time; and selling recyclables depends on markets and buyers. Saikawa has noted that creating access to waste collection could mitigate emissions and improve human and ecosystem health—an observation that points to infrastructure gaps beyond workshops alone.

Broader context includes high rates of household waste burning in Guatemala reported in earlier research and surveys, and a global plastic stream in which only a small share is ever recycled.

What Made This Possible

The work rests on partnership between U.S. and Guatemalan researchers and Xinca community members; NIEHS-linked research framing village-level interventions; workshops that let residents choose their own strategies rather than impose a single technology; and training of promotoras who sustain outreach between formal sessions. Pulitzer Center support enabled field reporting that brought the project to wider attention in August 2026.

Progress Toward Global Goals

Documented cleanup volume and community plans to reduce open burning align with SDG 3 (Good Health and Well-being) by targeting a source of toxic household and ambient pollution, and with SDG 11 (Sustainable Cities and Communities) and SDG 12 (Responsible Consumption and Production) through local waste management and recycling pathways. Women’s leadership as promotoras supports inclusive participation consistent with aspects of SDG 5 (Gender Equality). Alignment is outcome-based and partial; national waste systems and upstream plastic production remain largely unchanged. No UDHR article is claimed as a formal legal advance from this project alone.

Building on This Success

The following possibilities were generated with the assistance of AI to explore how this progress might be improved, expanded, or adapted. They are ideas for further investigation, not established findings or recommendations from the people featured in the original reporting.

Sustained bag counts and elected leaders show that community-chosen plans can move plastic out of fires and off roads. Next questions center on durable collection routes, exposure measurement, and fair recycling markets that do not shift harm elsewhere.

How are Ecolectivos workshops helping Xinca villages in Guatemala burn less plastic?

Through a participatory lens, Ecolectivos’s workshops function as structured choice architecture: researchers present health and waste information; villagers select tactics—cleanups, sorting for sale, reuse crafts—that fit daily life; promotoras reinforce habits door to door. The mechanism is social commitment plus repeated practice, not a new cookstove alone. An obstacle is tapering turnout after the first large cleanups; a measurable test would track bags collected and self-reported or sensor-based burning frequency per household over successive seasons in intervention versus control villages.

Through a public-health lens, the same design aims to cut inhalation and deposition of combustion toxins among women of reproductive age and children. The actor chain runs from university teams and UVG partners to village leaders to households. Obstacle: without reliable municipal pickup, residual waste may still be burned. A measurable test is before-and-after biomarkers or air samples tied to workshop cohorts, which the trial structure is built to support once full results are reported.

Three Promising Next Steps

1. Intervention: Extend scheduled waste pickup pilots linked to promotora networks. Actor: Municipal authorities with Ecolectivos and village committees. Mechanism: Replace open burning with collected loads. Obstacle: Road access and funding. Test: Tons collected versus estimated burn events over 12 months.
2. Intervention: Publish and share final exposure and behavior results from the randomized village design. Actor: Thompson, Saikawa, and UVG co-investigators. Mechanism: Evidence enables replication. Obstacle: Analysis and peer-review timelines. Test: Peer-reviewed effect sizes on burning frequency and pollutant markers.
3. Intervention: Expand local buy-back events for sorted recyclables with transparent pricing. Actor: Community groups and regional recyclers. Mechanism: Income reinforces sorting over burning. Obstacle: Price volatility and transport costs. Test: Kilograms sold and share of households participating quarterly.
