R&D PROJECTS

CONSTANT
EVOLUTION

Ongoing projects

During 2023, R&D projects continued to increase, reaching a record high in our history.

Countries involved

More than twenty countries around the globe are striving to benefit from this much-needed improvement in all the areas in which we work.

Research lines

Recycling of aggregates, Recycling of insulating mineral fibres, Recycling of wind turbine blade fibres, Reuse of steel, and the Digitisation of deconstruction processes.

Innovation products

Products that are an example of Lezama Demoliciones commitment to constant innovation and technological improvement.

ICEBERG

OBJECTIVE

Design, develop and validate innovative technologies for the reuse and recycling of building materials to produce high value, low impurity (less than 8%) materials, validating their effectiveness on an industrial scale in several case studies in Europe.

The project includes a number of lines of action among which the main ones are:

Demolition Support Tool: Development of a tool to create fast and accurate virtual models of buildings to be demolished, providing reliable estimates of the type and quantity of waste, as well as their environmental and economic impacts.

Digital Platform and Authentication System: Creation of a digital platform and authentication system based on wireless technologies to improve the identification and traceability of materials and products.

Improvement in Waste Sorting and Separation Technologies: Design and manufacture of a mobile unit for the automatic separation of mixed waste, equipped with hyperspectral sensors, machine learning, robotic arms and blower nozzles to optimise waste separation.

Improved Recycling and Purification Technologies: Optimisation of recycling and purification technologies for key materials such as concrete, ceramics, wood, gypsum, polyurethane foams, and glass, using advanced processes such as carbonation, micro-grinding, pyrolysis and solvolysis.

Development of Circular Products for Construction: Design and manufacture of new, durable and easily disassembled construction products, integrating between 30% and 100% recycled materials. This includes the development of eco-cements, eco-concretes, ultra-lightweight concretes, ceramic products with lower embedded energy, wood fibre and recycled polyurethane insulation panels, and gypsum boards with higher thermal insulation.

OBJECTIVE

Provide knowledge and update BIM methodologies to make them useful and affordable to companies in the construction industry, allowing benefits in terms of circularity and traceability, without requiring significant investments in software or equipment.

RECYCLEBIM

The project includes five main developments:

Development of a new methodology for surveying existing buildings.

Establish appropriate modelling rules and BIM information requirements to enable the BIM model to accommodate all relevant information for the complete analysis of its deconstruction.

Create an IFC-based tool for multi-criteria optimisation of deconstruction strategies and materials.

Strategic and optimised use of recycled demolition waste in 3D printed concrete for local digital construction practice.

Bring all previous developments together with a specific set of tools for municipalities to use in their tendering processes.

DRASTIC

OBJECTIVE

Develop and implement a comprehensive sustainability strategy in the building sector that achieves a significant and traceable reduction of greenhouse gas (GHG) emissions throughout the entire life cycle of buildings, from design to end-of-life, through the accelerated adoption of innovative design solutions, materials, techniques and business models.

The project includes three main aspects:

GHG reduction: Achieve a reduction in GHG emissions from the life cycle of buildings with a robust measurement and traceability system that allows for transparent verification and reporting of progress.

Adoption of Innovations: Increase the adoption of innovative design solutions, materials and techniques that reduce the life-cycle costs and impacts of buildings compared to conventional construction practices.

Circularity and Efficiency: Incorporate circularity and efficiency practices in construction and renovation projects, with a focus on maximising life-cycle performance and reuse of resources.
