Where does food go when it’s not sold every day in Phoenix businesses are faced with this simple but essential question. The solution is an opportunity, in Denali’s opinion. Denali transforms these common foods into green products that benefit the environment and finds value in uncooked food that lives longer. Plastic that is frequently thought of as a messy, time-consuming issue eventually becomes a component of a larger solution.  ,
Denali collaborates with restaurants, grocery stores, food service providers, food producers, and professional kitchens to collect leftover food and used cooking oil from across the city. It’s a frictionless, reliable service that keeps kitchens running smoothly for restaurants. It represents a significant shift in terms of the environment toward cleaner energy.  ,
Greener open spaces, healthier landscapes, and more adaptable ecosystems are now a result of food scraps from commercial kitchens or institutions, or unused food from a grocery store.  ,
Unused food continues to be one of the most important and underappreciated environmental issues in the United States, with nearly 40 % of it going unpasteurized and 24 % going to landfills. This national organics recycling company helped reduce lifecycle greenhouse gas emissions by up to 80 % compared to standard petroleum fuels by recovering and turning 106 million gallons of used cooking oil into feedstock for green biofuel in 2024.  ,
Denali is assisting in the transformation of that narrative in Phoenix. The company works with businesses, institutions, and municipalities to collect billions of pounds of non-edible food items annually, keeping them in circulation and out of landfills, and preventing the production of methane, a greenhouse gas that is more than 25 times more powerful than carbon dioxide. AllPro, a facility where used cooking oil is transformed into biofuel, is even owned by Denali.  ,  ,
The impact fast adds up. A ton of recovered food scraps can significantly lower greenhouse gas emissions and lead to new, valuable applications. The result is a system that, when combined with other systems across the entire metro area, constantly contributes to a more sustainable local economy.  ,
Denali’s management of the City of Phoenix’s burning facility is at the center of this endeavor. Compost plays a crucial role in an drier environment where water conservation is important and soil quality is important, promoting water retention, and reducing the need for chemical fertilizers. In order to support landscaping, agriculture, and land restoration in the region, natural materials are transformed into nutrient-rich compost, creating a closed-loop system that returns important nutrients to the soil.  ,

The value goes beyond collection for Denali’s customers. Denali’s programs are designed to seamlessly integrate into everyday life. The business offers regular pickups, spotless equipment, and transparent processes to prevent disruption. Businesses even gain access to reporting and tracking their impact, from recovered materials to emissions reduced. These metrics are important in a world where sustainability is significantly dependent on brand reputation and stakeholder expectations.
” Customers are asking more questions about what happens behind the scenes,” says Margaret Wilson, Denali’s general manager of the local Phoenix facility. Being ready to demonstrate that your food is being recycled into fuel and compost is powerful.
Denali’s model is flexible, attainable, and becoming more and more necessary. Solutions that extend the life of resources, reduce emissions, and conserve materials will only get more significant as cities grow and economic pressures get worse.  ,
Beyond the spiral food system, Denali’s presence extends to the Phoenix neighborhood. The SkyFire Film Festival, an event that brings up filmmakers and audiences to explore environmental issues, complex issues, and solutions through encouraging storytelling, is a proud sponsor of the company.  ,
Denali is even a committed member of the Arizona Compost Council, helping to advance composting practices and build up the state’s organics recovery infrastructure. These collaborations help ensure that the systems that support large-scale resource recovery are continuing to evolve in line with growing demand.
Denali also contributes to the development of novel ideas that can lead to significant change considerably beyond Phoenix by taking an active role in the Global Challenge Lab project with Arizona State University’s Thunderbird School of Management. Students from all over the world are collaborating on this initiative to address pressing issues of sustainability, offering new perspectives on topics like resource management and round economies.  ,
Denali is supporting businesses and communities in moving toward a more sustainable future in a region with both its challenges and opportunities. Not through philosophical objectives, but through regular actions that keep resources in use and have a long-lasting impact.
Collectively, these efforts aim to make a larger shift in how food is perceived, not as something to be left over, but as a resource that will continue to be useful. Denali’s work in Phoenix demonstrates how the appropriate infrastructure, partnerships, and vision can create opportunity in unanticipated areas, from clean fuel to nutrient-rich compost.
Sustainability is not a trend in Phoenix, where growth is moving at a quick pace; it is a necessity. One collection, one conversion, and one partnership at a time are now taking shape.
