A recent collaboration between the MIT School of Architecture and Planning and Fundación RIA (FRIA) in Galicia, Spain, highlights the growing intersection of sustainable design and biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More utilization. In a design studio course titled “Territory as Interior,” graduate students were tasked with repurposing abandoned industrial infrastructure on the Barbanza Peninsula. The initiative, led by lecturer Roi Salgueiro Barrio, aimed to develop architectural interventions that not only rehabilitate physical structures but also regenerate local economies by leveraging regional material resources and fiscal sectors.

The region faces distinct economic and ecological challenges, specifically its heavy reliance on pulp production and wood harvesting. This dependency has created economic vulnerability and significant waste streams in the form of post-harvest residue. The primary challenge identified by the research team was to find value in these forestry byproducts while simultaneously addressing the needs of the local agricultural sector. The situation demanded a systemic solution to close the resource loop and provide a sustainable economic alternative for the community, rather than a standalone architectural renovation.

To address these issues, graduate student Dong Nyung Lee proposed the development of a biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More production facility titled “From AshAsh is the non-combustible inorganic residue that remains after organic matter, like wood or biomass, is completely burned. It consists mainly of minerals and is different from biochar, which is produced through incomplete combustion.   Ash Ash is the residue that remains after the complete More to Soil.” Utilizing existing concrete and terra cotta blocks found on-site, the design outlines a plant capable of converting harvested wood residue into biochar through pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More. This process transforms the biomass in a low-oxygen environment, creating a stable carbon product. The facility is designed to integrate seamlessly with the local forestry industry, transforming what was previously considered waste into a valuable input for other sectors. The outcomes of this proposal extend beyond the theoretical. The design establishes a functional link between forestry and agriculture, where the produced biochar acts as a soil enhancer for local farmers. Fundación RIA recognized the project’s potential, hosting an exhibition in Santiago de Compostela to showcase how these designs address real-world territorial issues. This validation from a regional think tank confirms the increasing relevance of biochar systems in contemporary territorial planning and their potential to revitalize marginalized areas.

For the biochar industry, this case study illustrates the critical importance of integrating production facilities into existing community supply chains. Effective biochar deployment requires not just technological efficiency, but spatial and economic planning that aligns feedstockFeedstock refers to the raw organic material used to produce biochar. This can include a wide range of materials, such as wood chips, agricultural residues, and animal manure. More sources with local end-users. Facilities that act as bridges between sectors—like forestry and agriculture—are more likely to secure long-term sustainability and community adoption.
