In northern Arizona, the removal of woody biomass from forested land has garnered a high level of interest as threats of catastrophic wildfires have increased in recent years. Although there has been a great deal of vocal support for forest restoration, efforts on the ground are often stalled by complex federal contracting systems, a weak logging and sawmill industry, low-quality timber, and inabilities to guarantee long-term biomass supplies to processers. These barriers are exceedingly apparent in in the Flagstaff area, where the vast majority of forested land falls under the jurisdiction of the federal government and little infrastructure exists for wood product industries. In order to address these obstacles, forest stakeholders in Coconino County are actively searching for enterprises to utilize material that urgently needs to be removed from the surrounding forests. This project aimed to assist stakeholders in this endeavor by identifying and researching a number of practical and innovative woody biomass utilization enterprises that are suited to the existing regional infrastructure. While there are a variety of ways to process biomass, this project focuses on the following four end products because of their ability to use residual materials from harvest and sawmill operations, their low-tech nature, and the end product’s proximity to potential markets: biochar, compost, wood-plastic composites, and mushroom cultivation. Each of these products, and the processes used to create them, were analyzed and evaluated using a sustainable enterprise framework, and the final results were summarized in a portfolio for stakeholders in the region to review. Although this project offered just a glimpse of what is possible, the ultimate aim was to foster collaborative conversations regarding how forest restoration residues can be used in sustainable and innovative ways.

Domestic energy is an important component of our day to day lives and is something we cannot live without. Imagine how life would be without a means to cook our food, to warm our house, life would be unbearable. As we enjoy these comforts rarely do we stop to think

Domestic energy is an important component of our day to day lives and is something we cannot live without. Imagine how life would be without a means to cook our food, to warm our house, life would be unbearable. As we enjoy these comforts rarely do we stop to think what the opportunity cost is. For those using renewable sources, it is not a big issue, but for those who rely on wood fuel, they have to strike a delicate balance between need for fuel and the need to conserve the greatest support systems of their livelihoods, the forests. The main source of energy for households in many developing countries is biomass, mainly from forests and woodlands. The continued use of firewood and charcoal fuel puts a strain on forests, resulting in adverse effects on the environment such as prolonged droughts, loss of biodiversity, dwindling water resources, changing weather patterns among other sustainability challenges. An alternative to firewood to charcoal lies in biochar briquettes. This paper discusses the role of biochar briquettes in mitigating climate change and serves as a step by step guide on how biochar briquettes may be produced.

The commonly accepted goal of sustainability, to fulfill our current needs and maintain the worlds systems so future generations can also fulfill their needs, unifies efforts efficiently and aligns people with future thinking. But the concepts related, and their applications are fairly ambiguous in guiding people to what exactly they can do to make choices for sustainability. Individuals choices make a difference, adding up to societal shifts that change the world for the better. In such a complex world, there is a clear need for guidance through these systems. Sustainability and Resilience (S&R) is an optimistic podcast that journeys through thought-provoking science-based sustainability challenges with a bit of comedic relief. Listeners are entertained and become empowered to know what sustainable choices are, and why they are sustainable. S&R podcast uses systems thinking to pinpoint, realistic actionable items that empower listeners with a broad-spectrum sustainability knowledge for making everyday choices. Foundational research proved, developed and formed the idea of the podcast. Recording research lead to the ability to record test episodes, gather listener feedback and update the podcast concept. The podcast was officially created with the release of the debut episode that can anyone can listen to for free on all major platforms.
