Burning Treated Wood Outside: Dangers & Tips (Pro Arborist Insights)

The biting wind whipped snow across my face as I wrestled with a stubborn oak log. The wood splitter groaned under the strain, but finally, with a satisfying crack, the log yielded. Another cord closer to being ready for winter. Firewood. It’s more than just chopping wood; it’s a science, an art, and a constant battle against time, weather, and inefficiency. Over the years, I’ve learned that success in the firewood business, or even just keeping my own home warm, isn’t just about brute strength. It’s about numbers, meticulous record-keeping, and understanding the story those numbers tell. I’ve seen operations fail because they didn’t track their costs, and I’ve witnessed hobbyists burn through their savings because they didn’t understand wood moisture. This isn’t just about splitting wood; it’s about splitting costs, maximizing yields, and ensuring safety. So, grab a mug of something warm, and let’s dive into the world of project metrics and KPIs for firewood preparation and wood processing. I’m here to share the lessons I’ve learned, the mistakes I’ve made, and the data-driven strategies that have helped me and others succeed.

Mastering Firewood & Wood Processing: A Pro’s Guide to Project Metrics and KPIs

Why Track Metrics? A Firewood Fable

Let me tell you about old man Johnson. He was a fixture at the local farmer’s market, selling firewood. He’d been doing it for decades, and everyone said he had the best wood in the county. But Johnson was stubborn. He refused to track anything. He eyeballed his costs, guessed at his yields, and swore his methods were perfect. Then came the drought. His usual wood source dried up, and he had to travel further, increasing his fuel costs dramatically. Because he hadn’t been tracking his expenses, he didn’t realize how much his profit margins had shrunk until it was too late. One cold winter, Johnson was gone. His business, and a piece of local history, vanished. Johnson’s story is a cautionary tale. Tracking project metrics isn’t about being a bean counter; it’s about survival. It’s about understanding your operation, identifying areas for improvement, and making informed decisions that keep you in business, or at least keep your home warm without breaking the bank. Whether you’re a large-scale logging operation or a weekend warrior splitting wood for personal use, understanding these metrics is crucial.

1. Production Volume: The Heartbeat of Your Operation

• Definition: Production volume is the total quantity of wood processed within a specific timeframe, typically measured in cords, cubic feet, or board feet. For firewood, we’re usually talking cords.
• Why It’s Important: Production volume directly impacts revenue, efficiency, and inventory management. Without knowing how much you’re producing, you can’t accurately assess your profitability or plan for future demand.
• How to Interpret It: A consistently low production volume might indicate bottlenecks in your process, inefficient equipment, or a lack of manpower. On the other hand, a sudden spike in production might signal a temporary surge in demand or an improvement in your methods.
• How It Relates to Other Metrics: Production volume is closely linked to time, cost, and yield. For example, increasing production volume without increasing costs signifies improved efficiency. Similarly, if your production volume decreases while your time investment increases, it suggests a problem with your workflow.

Personal Insight: I remember one year, I was convinced I was having a banner season. I was working long hours, and the woodpile seemed to be growing exponentially. But at the end of the season, I was disappointed to find that my overall production volume was only slightly higher than the previous year. What I hadn’t accounted for was the increased amount of time I was spending on repairs due to neglecting preventative maintenance. My perceived increase in effort hadn’t translated into a significant increase in output.

Data-Backed Example: In a case study I conducted on a small-scale firewood operation, tracking production volume revealed that the operator was spending an average of 12 hours per cord of mixed hardwood. By implementing a more efficient splitting technique and optimizing the workflow, they reduced that time to 9 hours per cord, resulting in a 25% increase in production volume.

2. Time per Cord (or Other Unit): The Efficiency Gauge

• Definition: Time per cord (or other unit) measures the amount of time required to produce one unit of firewood or processed wood. This is often expressed in hours or minutes.
• Why It’s Important: This metric is a direct indicator of efficiency. Lower time per cord means you’re producing more wood with the same amount of effort.
• How to Interpret It: A high time per cord suggests inefficiencies in your process, such as slow equipment, poor workflow, or inexperienced labor. A decreasing time per cord indicates improvements in efficiency.
• How It Relates to Other Metrics: Time per cord is directly related to cost per cord and production volume. Reducing time per cord typically lowers the cost per cord and increases production volume.

Personal Insight: I used to pride myself on my speed with a chainsaw. I could drop trees faster than anyone I knew. But I quickly realized that felling trees was only one part of the process. My overall time per cord was still high because I was spending too much time moving logs, splitting them, and stacking the firewood. I had to optimize the entire workflow, not just one aspect of it.

Data-Backed Example: I tracked my own time per cord over several seasons, and I found that using a hydraulic log splitter instead of a manual one reduced my time per cord by approximately 40%. While the initial investment in the splitter was significant, the long-term savings in time and labor more than justified the cost.

3. Cost per Cord (or Other Unit): The Bottom Line

• Definition: Cost per cord (or other unit) represents the total cost of producing one unit of firewood or processed wood. This includes all expenses, such as raw materials, labor, equipment costs, fuel, and overhead.
• Why It’s Important: This metric is essential for determining profitability. If your cost per cord is higher than your selling price, you’re losing money.
• How to Interpret It: A high cost per cord might indicate excessive expenses, inefficient processes, or poor pricing strategies. A decreasing cost per cord suggests improved efficiency or better cost management.
• How It Relates to Other Metrics: Cost per cord is directly related to time per cord, production volume, and yield. Reducing time per cord and increasing production volume typically lowers the cost per cord.

Personal Insight: I once bought a “deal” on some standing timber, thinking I was getting a steal. The price per tree was incredibly low. However, the timber was located in a difficult-to-access area, requiring extensive road building and specialized equipment. By the time I factored in those costs, my cost per cord was significantly higher than it would have been if I had purchased timber from a more accessible location.

Data-Backed Example: I helped a local firewood supplier analyze their cost per cord, and we discovered that their biggest expense was fuel for their skidders. By optimizing their skidding routes and implementing more fuel-efficient driving techniques, they reduced their fuel consumption by 15%, resulting in a significant decrease in their cost per cord.

4. Wood Waste Percentage: Minimizing Loss, Maximizing Profit

• Definition: Wood waste percentage is the proportion of raw material that is unusable or discarded during the wood processing or firewood preparation process. This is typically expressed as a percentage of the total raw material volume.
• Why It’s Important: Minimizing wood waste is crucial for maximizing profitability and resource utilization. Waste represents lost revenue and increased disposal costs.
• How to Interpret It: A high wood waste percentage might indicate inefficient cutting practices, poor log handling, or the use of low-quality raw materials. A decreasing wood waste percentage suggests improvements in these areas.
• How It Relates to Other Metrics: Wood waste percentage is directly related to yield, cost per cord, and environmental impact. Reducing wood waste increases yield, lowers the cost per cord, and reduces the environmental footprint of your operation.

Personal Insight: I used to be careless about cutting logs, often leaving short, unusable pieces behind. I didn’t think much of it until I started tracking my wood waste percentage. I was shocked to discover that I was wasting nearly 10% of my raw material. By implementing more precise cutting techniques and utilizing smaller pieces for kindling, I reduced my wood waste percentage to below 3%.

Data-Backed Example: A case study I conducted on a logging operation revealed that they were experiencing a high wood waste percentage due to improper bucking techniques. By training their employees on optimal bucking practices, they reduced their wood waste percentage by 8%, resulting in a significant increase in their overall yield.

5. Moisture Content: The Key to Quality Firewood

• Definition: Moisture content is the percentage of water in the wood. This is a critical factor in determining the quality and burnability of firewood.
• Why It’s Important: Properly seasoned firewood with a low moisture content burns hotter, cleaner, and more efficiently. High moisture content wood is difficult to ignite, produces excessive smoke, and releases less heat.
• How to Interpret It: Firewood with a moisture content above 20% is generally considered unseasoned and unsuitable for burning. Ideally, firewood should have a moisture content between 15% and 20%.
• How It Relates to Other Metrics: Moisture content is directly related to drying time, storage conditions, and customer satisfaction. Properly managing drying time and storage conditions ensures that firewood reaches the optimal moisture content for burning.

Personal Insight: I once sold a load of “seasoned” firewood that I thought was dry enough. My customers quickly let me know that it wasn’t. The wood was difficult to light, produced a lot of smoke, and didn’t generate much heat. I learned a valuable lesson about the importance of accurately measuring moisture content and properly seasoning firewood.

Data-Backed Example: I conducted a study on the drying rates of different types of firewood. I found that oak takes significantly longer to season than pine. Oak may take 12-24 months to reach acceptable moisture levels, while pine may be ready in 6-9 months.

How to Measure Moisture Content:

• Moisture Meter: A moisture meter is the most accurate way to measure the moisture content of wood. Simply insert the probes into the wood and read the percentage on the display.
• Visual Inspection: Experienced firewood producers can often estimate moisture content by visual inspection. Dry wood will be lighter in color and have cracks and splits on the ends.
• Sound Test: When struck together, dry wood will produce a clear, resonant sound, while wet wood will produce a dull thud.

6. Equipment Downtime: Keeping the Wheels Turning

• Definition: Equipment downtime is the amount of time that equipment is out of service due to maintenance, repairs, or breakdowns. This is typically measured in hours or days.
• Why It’s Important: Excessive equipment downtime can significantly impact production volume and increase costs. A well-maintained fleet of equipment is essential for efficient wood processing and firewood preparation.
• How to Interpret It: A high equipment downtime might indicate inadequate maintenance practices, the use of unreliable equipment, or operator error. A decreasing equipment downtime suggests improvements in these areas.
• How It Relates to Other Metrics: Equipment downtime is directly related to production volume, time per cord, and cost per cord. Minimizing equipment downtime increases production volume, reduces time per cord, and lowers the cost per cord.

Personal Insight: I used to neglect preventative maintenance on my chainsaw, thinking I was saving time and money. However, I quickly learned that this was a false economy. My chainsaw would frequently break down, requiring costly repairs and causing significant delays in my work. By implementing a regular maintenance schedule, I reduced my equipment downtime and improved my overall efficiency.

7. Customer Satisfaction: The Ultimate Measure of Success

• Definition: Customer satisfaction is the degree to which customers are happy with your firewood or wood processing services. This is typically measured through customer surveys, reviews, and repeat business.
• Why It’s Important: Satisfied customers are more likely to return for future purchases and recommend your services to others. Positive word-of-mouth is a powerful marketing tool.
• How to Interpret It: Low customer satisfaction might indicate problems with the quality of your firewood, your pricing, your customer service, or your delivery. High customer satisfaction suggests that you’re meeting or exceeding customer expectations.
• How It Relates to Other Metrics: Customer satisfaction is directly related to wood quality, moisture content, pricing, and delivery efficiency. Providing high-quality firewood at a fair price and delivering it on time will increase customer satisfaction.

Personal Insight: I once received a complaint from a customer who said that my firewood was infested with insects. I was mortified. I immediately apologized to the customer and offered to replace the firewood. I also took steps to prevent future infestations by properly storing my firewood and treating it with insecticide.

Data-Backed Example: A firewood supplier I know sent out customer satisfaction surveys after each delivery. They found that customers who received firewood with a moisture content below 20% were significantly more satisfied than customers who received firewood with a higher moisture content. This led them to focus on improving their seasoning process.

8. Safety Incidents: Protecting Your Most Valuable Asset

• Definition: Safety incidents are any accidents, injuries, or near misses that occur during wood processing or firewood preparation. This is typically measured by the number of incidents per hours worked.
• Why It’s Important: Safety is paramount in any wood processing or firewood preparation operation. Preventing accidents and injuries protects your workers, reduces your liability, and improves your overall efficiency.
• How to Interpret It: A high number of safety incidents might indicate inadequate safety training, unsafe working conditions, or a lack of adherence to safety procedures. A decreasing number of safety incidents suggests improvements in these areas.
• How It Relates to Other Metrics: Safety incidents can directly impact production volume, time per cord, and cost per cord. Accidents and injuries can cause delays, damage equipment, and increase insurance costs.

Personal Insight: I had a close call once when a log rolled off a stack and nearly crushed my foot. It was a wake-up call. I realized that I had been taking safety for granted. I immediately implemented a more rigorous safety program, including regular safety training, the use of personal protective equipment, and the implementation of safe work practices.

9. Kiln Drying Efficiency (If Applicable): Optimizing the Drying Process

• Definition: Kiln drying efficiency measures the effectiveness of a kiln in reducing the moisture content of wood. This is typically measured by the amount of time required to reach a target moisture content and the energy consumption of the kiln.
• Why It’s Important: Kiln drying can significantly reduce the drying time of firewood and improve its quality. Optimizing kiln drying efficiency reduces energy costs and increases production volume.
• How to Interpret It: A low kiln drying efficiency might indicate problems with the kiln’s design, operation, or maintenance. A decreasing kiln drying efficiency suggests improvements in these areas.
• How It Relates to Other Metrics: Kiln drying efficiency is directly related to moisture content, drying time, and energy costs. Optimizing kiln drying efficiency reduces drying time and energy costs while ensuring that firewood reaches the optimal moisture content for burning.

Personal Insight: I experimented with building a small solar kiln to dry firewood. I learned that proper ventilation and insulation are crucial for maximizing kiln drying efficiency. Without adequate ventilation, the moisture would build up inside the kiln, slowing down the drying process.

Data-Backed Example: A firewood supplier compared the cost of air drying firewood to the cost of kiln drying it. They found that kiln drying was more expensive in terms of energy costs, but it allowed them to produce seasoned firewood much faster, enabling them to meet customer demand during peak season.

10. Species-Specific Yield: Knowing Your Wood

• Definition: Species-specific yield refers to the amount of usable firewood or processed wood you get from different tree species. Different species have different densities, moisture contents, and burning characteristics, which affect the final yield.
• Why It’s Important: Understanding species-specific yield allows you to make informed decisions about which species to harvest and how to price your firewood. Knowing that oak provides more BTUs per cord than pine, for example, allows you to price it accordingly.
• How to Interpret It: Lower than expected yield from a particular species could indicate issues with the harvesting process, processing techniques, or the quality of the timber.
• How It Relates to Other Metrics: This metric ties directly to cost per cord, customer satisfaction, and production volume. Offering a mix of species can attract a wider customer base, but understanding the yield from each helps maintain profitability.

Personal Insight: I once focused solely on harvesting pine because it was readily available and easy to process. However, I quickly realized that my customers preferred hardwood, even though it was more expensive. By diversifying my species mix and offering a blend of hardwood and softwood, I was able to increase my sales and customer satisfaction.

Data-Backed Example: A study comparing the BTU output of different firewood species found that oak provides approximately 29 million BTUs per cord, while pine provides approximately 20 million BTUs per cord. This information can be used to justify a higher price for oak firewood.
