The use of recycled materials in construction is increasingly popular in Indonesia, especially with the increasing need for sustainable development. In addition to reducing waste and carbon emissions, recycled materials can reduce costs and support economic circulation. Recycled materials such as concrete, steel, and plastic are increasingly in demand because:
- Cost Efficiency, recycled materials reduce production costs, making them a more economical option.
- Carbon footprint reduction of up to 30% compared to new materials.
- Supporting Economic Circulation, Recycling materials creates a cycle that extends the life of materials and reduces waste.
Types of Recycled Materials in Construction
- Recycled concrete, which is concrete from old buildings can be crushed and reused as a base material. With a process that meets standards, this concrete can meet the durability criteria required for construction.
- Scrap steel, which is steel from old structures can be melted and reused, producing materials that still meet construction qualification standards.
- Plastic materials, as an alternative to bricks or wall panels for small to medium-scale construction.
National Standards for the Use of Recycled Materials
The use of recycled materials in construction is regulated in SNI which ensures that these materials are safe and suitable for use, including:
- Durability and quality tests, such as SNI 03-2834 for concrete and SNI 03-1729 for steel.
- Environmental testing, regulating that recycled materials do not produce hazardous waste during the recycling process or their use.
- Production and processing quality, which must comply with safety standards to ensure that materials are qualified and environmentally friendly.
Implementation Process in Sustainable Construction
Large infrastructure projects such as the construction of toll roads and office buildings, have begun to use recycled materials to reduce their carbon footprint. An example of its application in Indonesia is recycled concrete for road base materials and low-rise building construction. This project proves that recycled materials can be part of the solution to sustainable development.
Using recycled materials in construction activities is an important step towards sustainable development. Complying with SNI helps ensure that these materials meet the aspects of durability and quality, while supporting the environment and reducing industrial waste.
