Investment analysis on sand and gravel separation and slurry water recovery

Let’s take a concrete mixing plant with an annual output of 300,000 cubic meters and equipped with 25 mixing trucks as an example. Here's how we can break down the costs and benefits: 1. **Initial Investment Costs**: - To install a complete set of equipment tailored to the scale and specific needs of each mixing station, the cost typically ranges between 200,000 to 550,000 yuan per set. - For civil engineering, while our company provides the design, the client handles the actual construction. This part usually costs around 20,000 to 100,000 yuan. - Therefore, the total initial investment cost would be approximately 360,000 yuan for the equipment plus 40,000 yuan for civil engineering, totaling 400,000 yuan. 2. **Cost Savings Calculation**: - **Sand and Gravel Recycling**: Every month, the station could save up to 1,562 yuan through recycling sand and gravel, which amounts to 0.04% of the average market price. - **Wastewater Recycling**: By reusing wastewater, the plant saves about 9,000 yuan per month. Given that they wash their 25 trucks twice daily using 2 tons of water each time, reusing the water significantly cuts down on consumption. - **Concrete Scrap Recycling**: Recycling concrete scraps saves another 6,510 yuan per month, considering the monthly scrap volume and the average price of sand and gravel. - **Reduced Cleaning Costs**: Labor costs for waste cleanup amount to 2,600 yuan per month. External waste transportation and landfill fees add another 1,400 yuan monthly. - **Environmental Protection Costs**: Without proper recycling systems, the plant might face additional environmental fines or compensation costs, which can be saved by implementing these measures. This saving is estimated at 5,000 yuan per month. - **Total Monthly Savings**: Summing up all the savings gives us a total of 28,072 yuan per month. 3. **Recovery Period Calculation**: - The recovery period is calculated by dividing the total investment cost by the annual savings. - So, 400,000 yuan divided by (28,072 x 12) equals approximately 1.4 years. **Note**: Clients can adjust these figures based on their specific situations to get a more precise recovery period.
