CO2-Binding Algae Fiber Composite for Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of pressure- and tension-resistant building materials like concrete, steel, glass, and aluminum requires large amounts of energy derived from fossil fuels, leading to significant CO2 emissions and contributing to global warming, necessitating a method to produce these materials in a CO2-neutral or CO2-free manner.
Innovation Solution
A process involving the extraction of CO2 from the atmosphere using algae in saltwater vessels, converting the resulting algae oil into synthetic fibers, such as carbon or aramid fibers, which are then combined with natural stone to create hybrid building materials, utilizing a combination of fossil and regenerative energy sources, eventually transitioning to purely regenerative energy, thereby permanently binding CO2 in the materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional building materials (concrete, steel, aluminum) are produced using fossil fuels, then sufficient energy is available for production, but large amounts of CO2 are released accelerating climate change
Solution Approach 1:
The patent converts CO2, previously a harmful emission, into a valuable raw material for producing algae oil through photosynthesis. Algae consume CO2 from flue gases to generate biomass that is converted into oil, which serves as feedstock for synthetic fiber production. This transforms the waste product into the foundation of a new material chain, simultaneously reducing emissions and creating economic value.
Solution Approach 2:
The patent fundamentally changes the chemical composition and properties of building materials by replacing traditional fossil-based materials with hybrid composites containing synthetic fibers derived from algae oil. These fibers exhibit superior tensile strength and lightweight characteristics compared to conventional materials, enabling new performance parameters in construction applications.
2Power
If fossil fuels are burned to produce energy for building materials, then production can proceed, but CO2 is added to the atmosphere that needs to be removed to limit warming to 2°C
Solution Approach 1:
The patent introduces algae as an intermediary organism that mediates between CO2 emissions from power plants and the production of valuable materials. Algae serve as a biological converter, taking in CO2 from flue gases and transforming it into biomass and oil, which then become raw materials for synthetic fiber production. This intermediary step decouples energy production from direct atmospheric CO2 accumulation.
Solution Approach 2:
The patent recovers CO2 that would otherwise be discarded into the atmosphere, converting it into a resource for algae cultivation. The CO2 separation and capture process retrieves this emissions stream, and the subsequent algae growth and oil extraction processes recover and valorize the carbon, transforming waste into wealth.
3Object-generated harmful factors
If synthetic fibers are produced from algae oil to replace conventional materials, then CO2 is permanently bound in building materials, but the production process requires significant energy input
Solution Approach 1:
The patent merges multiple functions into an integrated system: CO2 capture and separation, algae cultivation and oil extraction, and synthetic fiber production all occur within a unified industrial ecosystem. The flue gases from power plants directly feed the algae reactors, and the oil from algae processing becomes immediate feedstock for fiber production, eliminating intermediate waste streams and optimizing energy utilization across the entire chain.
Solution Approach 2:
The patent creates a multi-functional system where algae serve multiple purposes: they act as CO2 sinks, produce biomass for oil extraction, and the resulting oil serves as feedstock for fiber production. The synthetic fibers themselves provide multiple functions in building materials, including structural reinforcement, tensile strength, and potential insulation properties, maximizing the utility of each component in the value chain.

Function Achieved in This Case
This process reduces atmospheric CO2 levels by integrating CO2 into stable, long-lasting building materials, ultimately replacing conventional materials and enabling a transition to fossil fuel-free energy sources, achieving a CO2-neutral or negative balance in the building industry.
Implementation Method 1
CO2 is, for example, introduced into vessels with salt water in which algae growth is stimulated with the help of photosynthesis. The algae bind the carbon very quickly, faster than plants growing in air, releasing valuable oxygen in the process.
Implementation Method 2
The pyrolysis process required for carbon fiber production can also be carried out with the necessary high temperatures of over 1400 °C are supplied by bundling solar energy with parabolic mirror technology.

AI summary
The invention relates to a method for producing construction materials that are stable under pressure and tension in a process that is neutral with regard to CO2-emissions and has a negative CO2 emissions balance in a second step. Rapid growth of algae stimulated with the help of CO2 released when generating energy from fossil or regenerative fuels is used to obtain algae oil for the production of plastic fibers, which are used in particular for the production of carbon fibers, which are processed further so that, when combined with natural stone, they can replace, for example, CO2-intensive construction materials such as concrete, steel, glass and aluminum. The high temperatures required for the production of carbon fibers are also generated in a CO2-neutral manner by bundling sunlight using parabolic mirror technology, for example. Said procedure supplies the fundamental basis for forming an initially CO2-neutral, later CO2-negative balance-based industrial development in order to gain control over global warming of the earth and reverse it step by step over a period of time.
