RENCA aims to reduce the carbon footprint and safety risks associated with traditional construction methods by creating geopolymer building materials from industrial waste. This approach addresses the environmental issues caused by conventional cement production, which contributes to 8% of global CO2 emissions. Additionally, traditional building materials can be flammable and hazardous, while construction sites are often dangerous due to outdated practices and slow processes.
The Scale of the Problem
Globally, the construction industry's high carbon emissions contribute to climate change. Organic-based insulation materials are flammable, increasing fire risks. Conventional cement-based products corrode when exposed to water and sulfates, leading to mold growth and requiring costly chemical treatments. The unsafe working conditions and high rates of injuries at construction sites further exacerbate the problem.
RENCA's Solution
RENCA's geopolymer building materials are derived from industrial waste, reducing carbon emissions and energy consumption by 10 times compared to conventional cement. These materials are fire-resistant, withstanding temperatures up to 1200°C, providing enhanced safety. Geopolymers resist acid, salt, and water, offering greater durability. They don't contain large amounts of calcium, reducing mold growth risks.
The use of 3D printing technology in RENCA's solution reduces construction site risks by automating processes, removing the need for human labor in hazardous conditions. This approach allows for flexible and mobile construction, enabling onsite or offsite building.
RENCA's innovative solution addresses key issues in the construction industry, providing a safer, more sustainable, and efficient alternative to traditional materials. This contributes to a greener construction industry with a reduced carbon footprint and improved safety practices
RENCA's solution is to create sustainable building materials from industrial waste, using geopolymer technology and 3D printing to reduce carbon emissions and improve construction safety.
What is Geopolymer?
Geopolymer is a type of inorganic polymer derived from industrial by-products, offering an eco-friendly alternative to traditional cement. It reduces CO2 emissions and energy consumption by 10 times compared to conventional cementitious binders. This is due to the use of recycled materials, avoiding the energy-intensive calcination process associated with cement production.
How Does it Work?
RENCA's geopolymer building materials are produced by combining industrial by-products with a reactive liquid, forming a durable and stable inorganic polymer structure. This process uses significantly less energy and generates far fewer emissions than traditional cement production. The resulting geopolymer materials are fire-resistant, durable, and resistant to acid, salt, and water.
