In a quiet office at the University of Kashan, Elham Shafaii Moghadam, a researcher in social sciences, has uncovered a web of challenges that could either stall or accelerate the global recycling industry—one that holds immense potential for energy savings and resource efficiency. Her study, published in *Environment and Cross-Sectoral Development* (formerly *محیط زیست و توسعه فرابخشی*), uses the Interpretive Structural Modeling (ISM) approach to map out the 15 most critical barriers to waste recycling, revealing a layered system where some obstacles act as silent tipping points while others are mere symptoms of deeper systemic issues.
Shafaii Moghadam’s findings suggest that the recycling industry is not just a matter of good environmental stewardship—it’s a strategic economic lever, particularly for energy-intensive sectors. “Raw material shortages sit at the very top of the hierarchy,” she explains. “Without stable feedstock, even the most advanced recycling plants struggle to operate efficiently. This doesn’t just affect waste management—it ripples through supply chains, energy grids, and corporate sustainability targets.”
The research identifies seven structural levels of barriers, with government policy gaps—like the absence of subsidies or tax incentives—ranked at the bottom. These may seem like slow-moving factors, but Shafaii Moghadam emphasizes their long-term importance. “Policies aren’t just paperwork,” she says. “They shape investment decisions. If a recycler can’t get tax relief or secure low-interest loans, they’re competing on uneven ground against landfills and incinerators, which have lower operational transparency and fewer environmental constraints.”
At the top of the hierarchy, raw material scarcity and high technology costs emerge as dominant forces. These aren’t just environmental concerns—they’re commercial red flags. For energy companies, particularly those investing in circular economy models, this means that securing recycled feedstock isn’t just a sustainability goal—it’s a supply chain imperative. “If you’re in the energy sector and you’re planning to pivot toward recycled materials to cut emissions, you need to know where your inputs are coming from,” Shafaii Moghadam notes. “A power plant switching from virgin aluminum to recycled feedstock can cut energy use by up to 95%. But if the recycled material isn’t available at scale, that transition stalls.”
The study also highlights fierce competition between recycled and virgin materials. “Producers of virgin materials often benefit from lower production costs and established supply chains,” she says. “Recyclers, especially in the formal sector, face a constant uphill battle in pricing. That’s not just a market failure—it’s a missed opportunity for energy savings and carbon reduction.”
What makes this research particularly compelling is its use of ISM to reveal not just *what* the barriers are, but *how* they interact. Raw material shortages don’t just limit production—they inflate costs at every level, from collection to processing. High technology costs aren’t isolated; they’re reinforced by low profitability and weak policy support. “This isn’t a list of problems,” Shafaii Moghadam observes. “It’s a map of leverage points. If we address the right barriers first—like stabilizing raw material supply and reducing technology costs—we can unlock systemic change.”
For energy companies, this means rethinking procurement strategies. Investing in recycling infrastructure isn’t just about corporate social responsibility—it’s a hedge against volatile raw material markets and a pathway to lower energy intensity. The research suggests that long-term policy commitments, such as subsidies and tax breaks, could catalyze private investment, making recycled materials more competitive and reducing reliance on energy-intensive virgin production.
As the circular economy gains momentum, Shafaii Moghadam’s work offers a critical reminder: recycling isn’t just about waste diversion. It’s about reimagining supply chains, reducing energy demand, and creating a more resilient industrial ecosystem. The barriers are real, but so are the opportunities—especially for sectors that stand to benefit the most from a shift toward sustainable materials.
