Reclaiming Residues: Brazil Nut Shells and the Future of the Development of Circular Construction Materials

About the Project

This PhD project explores the potential of Brazil nut shells and other agro-forestry residues from the Amazon rainforest as innovative, sustainable construction materials. With growing global demand for low-carbon solutions and circular economy models, the project addresses two critical challenges: reducing waste and promoting inclusive development in rainforest communities. Forestry by-products such as Brazil nut shells are abundant yet underutilised, often discarded despite their promising mechanical and thermal properties. This research aims to transform these materials into viable construction components, contributing to both environmental sustainability and socio-economic resilience.

The project will begin with the characterisation of Brazil nut shells and similar residues, assessing their physical, chemical, and structural properties through laboratory testing. Mechanical strength, thermal insulation, and durability will be evaluated to determine suitability for various construction applications. Prototype materials will be developed and tested under controlled conditions to assess performance and compliance with building standards. Lifecycle assessments will be conducted to quantify carbon savings, resource efficiency, and environmental impact compared to conventional materials.

A key component of the project is community engagement. Participatory design workshops will be held in Amazonian regions to co-develop solutions that reflect local needs, cultural practices, and traditional knowledge. Collaboration with Brazilian industries will support pilot applications and integration into existing supply chains, enabling scalability and long-term impact.

The project will be co-supervised by Dr Lina Bufalino from the Federal Rural University of the Amazon (UFRA), a leading institution in sustainable development and agro-industrial innovation in the Amazon region, ensuring strong regional insight and academic collaboration. The expected outcomes include sustainable, waste-derived construction materials; a replicable model for community-inclusive industrial decarbonisation; and strengthened research and industry ties between the UK and Brazil. By bridging material innovation with environmental and social sustainability, this project offers a holistic approach to regenerative design and low-carbon construction. It positions agro-forestry waste not as a liability, but as a valuable resource for building a more equitable and sustainable future.

Candidate requirements:

Applicants must have, or be about to obtain, a UK Honours degree 1st or 2.1, or international equivalent, in a relevant subject. A master’s level qualification would also be advantageous.

A strong background in one or both fields of civil engineering or materials science, with experience or willingness to develop skills in laboratory testing, material characterisation, and prototype development. Familiarity with lifecycle assessment tools and environmental modelling is desirable; expertise is not required. A demonstrated interest in low-carbon construction, circular economy, and regenerative design. Able to work across disciplines, integrating technical research with social engagement and design thinking. Strong communication skills with a willingness to participate in field visits and stakeholder workshops in the Amazon region. Prior experience with community-based research or participatory methods is a plus. Fluency in Portuguese or Spanish is beneficial but not required. Ability to produce good-quality research articles.
