Exploring Opportunities for Woody Biomass Utilization in Coconino County, Arizona

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.

Biochar Briquettes: Alternative to Firewood and Charcoal Fuel

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.

Gumantar Coffee Project

The community of Gumantar in Lombok, Indonesia, one of the poorest regions of the island, is home to a large number of coffee farmers. Due primarily to production quality, these farmers struggle to earn a sufficient wage. While trying to provide for their families, the local environment often suffers. The persistent poverty has resulted in lower education levels, health care barriers, and decreased well-being. In an effort to empower the farmers and promote sustainable development, I have created a best practice guide that looks at five coffee production factors. The local farmers have specifically requested case supported, science-based information regarding these factors. The factors include farming techniques, drying practices, coffee specific small business skills, financial literacy, and coffee certification requirements. Access to information regarding these topics is intended to help reduce poverty, increase accessibility to quality education, and support local economic development, environmental health, and community health and well-being.

Paving the Road for Community Support in a Garden Based Learning Program

This project focuses on building capacity for the long-term viability of the garden based learning program at Martin Luther King Early Childhood Center through cultivating relationships with local organizations and businesses. Building upon Matthew Waldman’s 2018 MSUS project work with this school and The Farm at South Mountain, this project’s purpose was to explore ways to integrate the greater school community and allow them to share their vision for an outdoor community space.
The intervention tool used to engineer this collaborative mindset was individual square foot garden boxes that each child in the 2019 student body was able to decorate and take home.
As a tangible piece of this Culminating Experience, I have installed a pollinator garden that has been registered with Monarch Waystation Program. This space serves as a celebration of the school’s mascot and provides a totem for the collective action of the community.
With the onset of COVID-19 and the implementation of local, state and federal guidelines, the school has been closed since March and has curtailed the anticipated deliverables.
