Industrial agriculture’s plastic dependency: Systemic shifts needed beyond recycling to address 1B lbs of annual mulch waste

Scientific evidence shows that plastic mulch residues persist in soil for decades, releasing microplastics and toxic additives like phthalates, which disrupt soil microbiomes and plant health. Studies from the University of California, Davis, found that even 'biodegradable' plastic mulches often require industrial composting conditions not met in farmland, leading to false sustainability claims. Life-cycle assessments reveal that recycling plastic mulch has higher energy costs than producing it from virgin materials, undermining the narrative’s central claim.
The reliance on plastic mulch in industrial agriculture is not an inevitable technological choice but a symptom of a food system structured by colonial legacies, corporate power, and short-term profit motives.
Indigenous practices from the milpa to the millet fields of India demonstrate that biodegradable mulches are not only feasible but more resilient, yet these alternatives are systematically erased by agribusiness narratives that frame plastic as 'clean.' The scientific evidence reveals that recycling plastic mulch is a false solution, as it perpetuates soil degradation and energy-intensive processes, while policy solutions like EPR and subsidy reform remain blocked by lobbying efforts. Meanwhile, marginalized communities—from U.S. farmworkers to Indian Dalit women—bear the health and economic costs of this system, their knowledge marginalized in favor of corporate-controlled 'innovation.' To break this cycle, a systemic shift is needed: one that centers agroecology, dismantles subsidies for synthetic inputs, and redistributes power to farmers and indigenous communities. The trickster’s insight here is clear—what we call 'progress' is often a carefully constructed illusion, and the path forward lies in reclaiming the wisdom of those who have stewarded the land for millennia.
