Let’s take a concrete mixing station with an annual output of 300,000 cubic meters and 25 mixing trucks as an example. Here's a detailed breakdown of the investment and cost-saving aspects:
### 1. Investment Costs:
- **Equipment Installation:** Depending on the scale and specific requirements of each mixing station, the cost of setting up a complete set of equipment ranges from approximately 200,000 to 550,000 yuan per set.
- **Civil Engineering:** The civil engineering portion of the project is handled by the customer themselves, with our company providing support. This cost typically falls between 20,000 and 100,000 yuan.
Thus, the total investment cost equals the sum of the equipment cost and civil engineering cost: 360,000 + 40,000 = **400,000 yuan**.
### 2. Cost-Saving Calculations:
- **Sand and Gravel Recycling:** Assuming the monthly output of sand and gravel recycling is 30,000 cubic meters, the estimated savings would be calculated as follows:
30,000 m³ x 1.86 x 0.04% x 70 yuan/m³ = **1,562 yuan/month**.
- **Wastewater Recycling:** For 25 mixers, if each mixer is washed twice daily using 2 tons of water per wash, but 0 tons are used from recycled water, the monthly savings would be:
(25 x 2 x 2 - 0) x 30 days x 3 yuan/ton = **9,000 yuan/month**.
- **Concrete Scrap Recycling:** If the monthly volume of scrap concrete is 50 cubic meters, the savings would be:
50 m³ x 1.86 x 70 yuan/m³ = **6,510 yuan/month**.
- **Cleaning Costs Savings:** By reducing the need for cleaning personnel and external disposal, the savings are:
- Labor: 2 x 1,200 yuan/month + 200 = **2,600 yuan/month**
- External Freight: (20 yuan/truck x 10 trucks + 500 yuan) x 2 = **1,400 yuan/month**
- **Environmental Protection Costs:** Saving on sewage discharge fees and related compensation to surrounding residents amounts to **5,000 yuan/month**, bringing the total environmental cost savings to **7,000 yuan/month**.
Adding these savings together, the total monthly cost savings equal:
1,562 + 9,000 + 6,510 + 2,600 + 1,400 + 7,000 + 0 = **28,072 yuan/month**.
### 3. Payback Period Calculation:
The payback period is determined by dividing the total investment cost by the annualized savings:
400,000 ÷ (28,072 x 12) = **1.4 years**.
### Additional Notes:
These calculations are based on the assumption that there are no additional expenditures unless specified. Customers can adjust these figures based on their specific circumstances to obtain a more precise payback period.
