Profitability Analysis: Is Composting Worth It?

To determine if composting is a profitable venture, you need to compare your total costs with your potential revenue. Let’s revisit our case study and assume that the arborist business can sell their compost for \$40 per cubic yard.

Revenue:

100 cubic yards of compost x \$40/cubic yard = \$4,000 per year

Profit (Loss):

Year 1: \$4,000 (revenue) – \$8,320 (costs) = -\$4,320 (loss)
Year 2 and beyond: \$4,000 (revenue) – \$4,320 (costs) = -\$320 (loss)

In this scenario, the composting operation is not initially profitable. However, there are several ways to improve profitability:

Increase Sales Volume: Sell more compost by expanding your marketing efforts or targeting new customer segments.
Reduce Costs: Look for ways to reduce your costs, such as sourcing cheaper materials, using more efficient equipment, or reducing labor costs.
Increase Price: If your compost is of high quality, you may be able to charge a premium price.
Secure Grants or Subsidies: Some government agencies offer grants or subsidies for composting operations.

Let’s assume the arborist business can increase their sales volume to 150 cubic yards per year and reduce their horse manure transportation costs to \$300 per year.

Revised Revenue:

150 cubic yards of compost x \$40/cubic yard = \$6,000 per year

Revised Costs (Year 2 and beyond):

Land Rental: \$100
Permitting: \$100
Horse Manure Transportation: \$300
Nitrogen Amendments: \$200
Water: \$100
Labor: \$2,000 (increased due to higher volume)
Fuel: \$600
Maintenance and Repair: \$250
Electricity: \$60
Insurance: \$500
Accounting and Legal: \$200
Total: \$4,410

Revised Profit:

\$6,000 (revenue) – \$4,410 (costs) = \$1,590 (profit)

In this revised scenario, the composting operation is now profitable. This highlights the importance of carefully analyzing your costs and revenue potential and making adjustments as needed.

Here are some tips for optimizing your costs:

Utilize Existing Resources: You already have access to wood waste, which is a major cost for many composting operations.

Calculating Volume: Board Feet vs. Cords vs. Cubic Yards

Understanding how to calculate volume is crucial for both costing your wood waste and pricing your finished compost. Here’s a breakdown:

Board Feet: Used to measure the volume of sawn lumber. One board foot is 1 inch thick, 12 inches wide, and 12 inches long. This isn’t directly relevant to composting, but it’s a common measurement in the wood industry.
Cords: Used to measure the volume of firewood. A standard cord is 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet. This includes air space between the logs.
- Conversion: One cord of loosely piled wood chips is approximately equal to 3-4 cubic yards.
Cubic Yards: The most common unit of measurement for compost and mulch. One cubic yard is 3 feet high, 3 feet wide, and 3 feet long, totaling 27 cubic feet.

Formula for Estimating Cubic Yards from Wood Waste:

Estimate the volume of your wood waste in cubic feet.
Divide the volume in cubic feet by 27 to convert to cubic yards.

Example:

Let’s say you have a pile of wood waste that is 10 feet long, 5 feet wide, and 4 feet high.

Volume in cubic feet: 10 ft x 5 ft x 4 ft = 200 cubic feet
Volume in cubic yards: 200 cubic feet / 27 cubic feet/cubic yard = 7.4 cubic yards

This is just an estimate, and the actual volume may vary depending on how tightly the wood waste is packed.

Drying Time Estimation: Moisture Content Matters

The moisture content of your wood waste and compost is crucial for both decomposition and saleability. Here’s how to estimate drying time:

Factors Affecting Drying Time:
- Wood Species: Hardwoods generally take longer to dry than softwoods.
- Size of Wood Pieces: Smaller pieces dry faster than larger pieces.
- Weather Conditions: Warm, sunny weather with low humidity promotes faster drying.
- Air Circulation: Good air circulation helps to remove moisture.
Estimating Drying Time:

There’s no simple formula for estimating drying time, as it depends on so many factors. However, here are some general guidelines:

*   **Air Drying Wood Waste:** Wood waste can take several months to a year or more to air dry, depending on the factors listed above. *   **Composting:** The composting process itself will help to dry out the wood waste. Aim for a moisture content of 50-60% for optimal decomposition.

Tips for Reducing Drying Time:

Chipping or Grinding: Breaking down the wood waste into smaller pieces will significantly reduce drying time.
Turning: Regularly turning the compost pile will improve air circulation and help to dry out the material.
Covering: Covering the compost pile during rainy weather will prevent it from becoming too wet.
