Cool business ideas for startups and business development

ReviveBlocks: LEGO concepts in the real world, the recycled Plastic hollow blocks.

I have read and some interesting articles on using recycled material or alternative materials for building and construction and wondered. What would it take to make a proposal for using Recycled Plastic hollow building blocks defined below can this be an economic alternative to supplement to regular building blocks and what would be the process to investigate the viability

Recycled Plastic hollow blocks

Recycled Plastic hollow building blocks are made from recycled Plastic to form a shell. It is filled. with a slurry\ aggregate made of cement or an alternative binder and a blend of desert sand, hemp or wood waste and recycled plastic (a coarse aggregate) mixed and compressed (and capped with a cover?) then dried. The Recycled Plastic hollow blocks will have micro holes on its surface to enable drying. The premise is to reduce the cost of basic building as a supplement and not initially as a replacement. The cost reduction is not to building complete structures out of it but to supplement traditional or alternative builds. This saving is the economic replacement value of substitution. It should be noted that ReviveBlocks (or TerraPlast Bricks, RecycleCore Blocks, EcoFiller Blocks etc are placeholder names)

Building blocks are defined:  concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit (CMU). A concrete block is one of several precast concrete products used in construction. The term precast refers to the fact that the blocks are formed and hardened before they are brought to the job site. Most concrete blocks have one or more hollow cavities, and their sides may be cast smooth or with a design. In use, concrete blocks are stacked one at a time and held together with fresh concrete mortar to form the desired length and height of the wall or a block of stone or other material, larger than a brick, used in building

Biggest Consideration: Getting the aggregate\ mix right

Research in the field of creating building blocks using cement binders, alternative binders, and a mixture of ordinary sand, desert sand, and recycled materials has been ongoing for several years, with a focus on sustainable and environmentally friendly construction practices. These efforts aim to reduce the carbon footprint of traditional construction materials and address the global demand for sustainable building solutions. Some key areas of research and innovation in this field include:

1. Alternative Binders:

   – Geopolymer concrete: Geopolymers are a class of inorganic polymers that can replace traditional cement binders. They are often produced using industrial by-products like fly ash or slag. Researchers have been working on developing geopolymer-based building blocks that are more environmentally friendly and durable.

   – Alkali-activated materials: Alkali-activated materials are another class of alternative binders that can be used to create building blocks. They can be made using various waste materials and have shown promise in reducing carbon emissions compared to traditional cement.

2. Recycled and Waste Materials:

   – Incorporating recycled aggregates: Researchers are exploring ways to incorporate recycled concrete or other construction waste materials into block production. This not only reduces waste but also conserves natural resources and reduces the environmental impact of construction.

   – Plastic waste: Some studies have investigated the use of recycled plastic waste in building block production. These blocks can be lightweight and have insulating properties, making them suitable for specific applications.

3. Desert Sand and Sustainable Sourcing:

   – Desert sand is often not suitable for construction due to its unique properties, which can lead to poor structural integrity in traditional concrete. Researchers have been working on methods to modify desert sand or to blend it with other materials to make it suitable for construction.

   – Innovative block designs are being developed to enhance the structural integrity, insulation properties, and ease of construction. Some researchers are exploring novel block shapes and interlocking systems to improve construction efficiency.

5. Performance and Durability:

   – Research is ongoing to ensure that these alternative building blocks meet the necessary performance and durability standards required for construction.

6. Carbon Capture and Utilization:

   – Some research explores the possibility of incorporating carbon capture and utilization (CCU) technologies into building materials to reduce their carbon footprint.

These efforts aim to make construction more sustainable, reduce greenhouse gas emissions, and address the environmental challenges associated with traditional building materials. However, it’s essential to note that while many promising developments are being researched, widespread adoption of these alternative building blocks may still require overcoming economic, regulatory, and market barriers.

2.Mix  Considerations

Solar heating desert sand with plastic aggregate to use as a component for building materials could have both advantages and challenges. Here are some potential effects and considerations:


1. Improved Sand Suitability: Desert sand, typically composed of fine grains, often lacks the ideal particle size distribution for traditional construction materials. Heating and mixing it with plastic aggregates could alter its properties, making it more suitable for building blocks by providing cohesion and stability.

2. Sustainable Use of Plastic Waste: Incorporating plastic aggregates into construction materials can help recycle plastic waste and reduce its environmental impact. It can contribute to solving the issue of plastic pollution and promote sustainability in the construction industry.

3. Enhanced Insulation: Depending on the plastic type and the way it’s mixed with sand, the resulting composite material may have insulating properties, which can be beneficial for certain construction applications, particularly in regions with extreme temperatures.


1. Material Properties: The properties of the resulting material will depend on factors such as the type and quantity of plastic used, the heating process, and the sand-to-plastic ratio. Achieving consistent and predictable material properties may be challenging.

2. Structural Integrity: While incorporating plastic waste into building materials can be environmentally friendly, it may affect the structural integrity of the final product. Ensuring that the material meets the required structural standards and durability can be a complex engineering challenge.

3. Thermal Stability: The heat resistance of the plastic aggregate must be considered. Some plastics may not withstand the high temperatures required for mixing with desert sand, potentially releasing toxic fumes or undergoing structural changes.

4. Environmental Impact: The environmental impact of the heating process and the source of energy for heating the materials should be evaluated. Using renewable energy sources for the heating process would align with sustainability goals.

5. Market Acceptance: Widespread adoption of such materials may require regulatory approvals and market acceptance, which can be influenced by factors like cost, performance, and safety.

6. Long-Term Durability: The long-term durability of the material in various environmental conditions and exposure to UV radiation should be studied to ensure its viability for construction.

7. Compatibility with Construction Methods: Construction techniques and methods may need to be adapted to accommodate these new materials. It’s important to ensure that the building blocks are compatible with standard construction practices.

Research and testing are essential to address these challenges and understand how heating desert sand with plastic aggregate can be a viable and sustainable building material. It’s important to work with engineers, materials scientists, and construction professionals to develop and validate these materials for specific applications while considering the local environmental conditions and regulations.
