Cannabis Recycling Solutions: How SunMed Growers and The High 5 Initiative Are Shaping a Greener Industry

The cannabis industry is experiencing rapid growth, and with that expansion comes an equally significant environmental challenge: packaging waste. Due to strict regulations, cannabis products must be sold in child-resistant, tamper-evident, and opaque packaging. While these requirements help ensure safety and compliance, they often result in the use of single-use plastics and mixed materials that are notoriously difficult to recycle through traditional means.

Fortunately, a new wave of environmentally conscious organizations and companies are stepping up to the challenge. From grassroots recycling movements to large-scale cultivation operations, leaders like the High 5 Initiative and SunMed Growers are championing sustainability in cannabis.

The High 5 Initiative: Tackling Cannabis Packaging Waste

Founded in Maryland, the High 5 Initiative is a nonprofit organization with a mission rooted in environmental conservation. They’ve honed in on one of the cannabis industry’s biggest environmental pain points: packaging waste, particularly the kind made from #5 polypropylene plastics. These plastics are common in cannabis containers, but they’re rarely recycled properly due to limitations in single-stream recycling programs.

To combat this issue, the High 5 Initiative launched their "Return to Retail" recycling program—a first-of-its-kind effort in Maryland that empowers cannabis consumers to return their used packaging to participating dispensaries. Once collected, these containers are manually sorted, cleaned, and processed into post-consumer resin, which can then be used to manufacture new, useful products.

Over the past three years, the initiative has achieved a remarkable impact, diverting more than 550,000 containers and over 18,000 pounds of plastic from landfills. Their work not only reduces environmental harm but also raises consumer awareness about the long-term impact of cannabis waste. By closing the loop between consumers and recyclers, the High 5 Initiative is helping to normalize sustainability within a traditionally waste-heavy industry.

SunMed Growers: Integrating Sustainability from Cultivation to Packaging

As Maryland’s largest cannabis cultivator, SunMed Growers is setting a gold standard for sustainability across the entire production cycle—from cultivation to packaging.

SunMed operates out of a massive, state-of-the-art "Dutch-style" greenhouse, which harnesses full-spectrum sunlight to grow cannabis in a way that’s both energy-efficient and environmentally friendly. By relying less on artificial lighting and HVAC systems, SunMed significantly reduces its carbon footprint compared to indoor grows.

But their sustainability efforts don’t stop at cultivation.

SunMed partners with packaging experts to create environmentally conscious solutions that meet both regulatory requirements and sustainability goals. Unlike microplastics, which never fully break down, biodegradable and compostable materials like wood pulp, bamboo, and rice husk offer an eco-friendly alternative. Landfill-degradable bags for products like flower and edibles also cut back on excess plastic and help reduce waste. 

The Broader Impact and Future Outlook

The combined efforts of The High 5 Initiative and SunMed Growers underscore a critical truth: sustainability in cannabis is not just possible—it’s essential. As more consumers begin to prioritize environmental values when making purchasing decisions, these forward-thinking initiatives serve as a blueprint for the rest of the industry.

Retailers and cultivators alike can learn from their example:

• Recycling programs are accessible, community-driven and impactful.

• Eco-friendly packaging doesn’t mean you sacrifice compliance or functionality.

• Sustainability practices can enhance brand trust and customer loyalty.

Looking ahead, increased collaboration between cannabis companies, recyclers and consumers will be key to building a greener future. With the groundwork laid by the High 5 Initiative and brands like SunMed, the industry is already proving that environmental stewardship and cannabis innovation can go hand-in-hand.
