Common challenges in handling large volumes of excavated material and their solutions

Loose masses without bearing capacity

• Problem: Loose spoil can lack stability and load-bearing capacity, making it difficult to use directly in construction projects.
• Solution: Possible solution could be to stabilize loose masses with bentonite or lime in a high capacity Screening plants .

Mixed soils with high moisture content

• Problem: Excavated material with high moisture content can be difficult to handle and reuse directly.
• Solution: Possible solution is to sort by size with star sieves allowing topsoil to be reused on site or sold.

Contaminated soils

• Problem: Contaminated soils can spread harmful substances and require special treatment.
• Solution: Possible solution is to sort out fine fraction where often pollutants are located and blow out organic which often absorbs pollutants.

Too much large stone to be used as soil

• Problem: Large stones cannot be used directly as soil and require further processing.
• Solution: A possible solution is to divide the stone into several fractions, such as macadam, carrier layer, sand, etc. These fractions can then be used to replace virgin material.

The right technology to recycle excavated material

1. Mobile laundry facilities
   • Mobile washing plants are effective in dealing with muddy and sticky masses. They can separate small fractions and reduce the need for landfill by enabling on-site recycling. These plants are cost-effective and can be quickly set up and removed, making them ideal for different project sizes .
2. Wind sifting
   • Wind screening effectively separates lighter materials from heavier ones, allowing organic material to be recycled and improving recycling efficiency. This reduces waste and improves the usability of the material .
3. Density separation
   • Using water bath to separate materials based on their density is an effective method of managing mixed waste. This allows materials such as wood and inert materials to be recycled, increasing recycling rates and reducing landfill requirements .
4. Reuse of aggregates
   • By breaking down rocky spoil into usable materials, it can be reused in new construction projects, saving natural resources and reducing emissions from new mining. This is a sustainable approach that promotes the circular economy .

Recycling of excavated material for sustainable resource management

Efficient management and recycling of excavated material is crucial for sustainable resource management. By implementing advanced technologies and solutions, we can reduce the amount of waste sent to landfill, conserve natural resources and protect the environment for future generations. Norditek offers a wide range of methods and equipment to meet these challenges in a cost-effective and environmentally friendly way .
