Description
Kamen Sirač is in stone processing business for 140 years.
The products are primarily used in construction, metal processing and the chemical industry. Company experienced damage during Homeland War, and years were needed before production was restored to pre-war level. Kamen Sirač is a key exporter of dolomite lime produced from dolomite raw material to the steel industry in nearby countries.
Project:
Stone aggregates for the construction industry are produced in a production process consisting of drilling, blasting, material transportation, crushing and sorting in different plants. Part of the material is not suitable for processing in a plant due to its physical and mechanical properties. Still, it is separated and disposed of in a landfill.
The landfill contains unsorted stone material and earth that has been accumulating at the landfill for years. In certain cases, it is suitable for use in the construction sector (water and transport infrastructure construction projects).
The promoter cannot currently process unclassified stone material and soil from landfill, and in case of need for unclassified stone must go to new exploitation. This is inefficient, it requires using large amounts of resources, including fossil fuels. It affects an increase in CO2 emissions because new exploitation requires blasting. Also, each new exploitation consumes the quarry and reduces its useful life.
This project is about investment into mobile scalpel and mobile impact crusher. New equipment will enable reuse of materials collected from the landfill in quarry. With assistance from IDN, greener production process will be created, additional marketable stone aggregate will be produced for construction industry (mainly in constructing roads, railways, and water supply infrastructure).
In addition to better utilization of natural resources and lower CO2 emissions, project will lead to increase of operational revenues/profit of Kamen and make it more competitive.
Summary of project results
The project addressed the inefficiency of quarry operations caused by the inability to process unclassified stone material from landfills, leading to resource wastage, increased CO2 emissions, and reduced quarry lifespan due to the need for new exploitation. Additionally, it tackled the environmental and economic challenges associated with fossil fuel consumption and operational inefficiencies.
The key activities of the project included investing in mobile scalpel and mobile impact crusher equipment, This equipment enables the processing and reuse of unclassified stone material from the landfill. This created a greener production process and generated additional marketable stone aggregate for the construction industry.
The project resulted in the more efficient use of natural resources by enabling the processing and reuse of unclassified stone material from the landfill, reducing the need for new quarry exploitation and lowering CO2 emissions. The primary beneficiaries are Kamen Sirač, which saw increased operational revenues, profits, and competitiveness, and the construction industry, which gained access to additional marketable stone aggregates. The local community and environment also benefited from reduced environmental impact and resource conservation.
Summary of bilateral results
The partner, IDN helped Kamen Sirac to green their production process.
