Wane is the uncut edge of a board that has been milled from a tree. Essentially it is the 'bark' edge so instead of having a square cut piece of wood you have the contour of the outer edge of the tree on one or both sides of milled board. Once the board is 'edged' or squared off then you have dimesional lumber.

Wane in lumber refers to the presence of the rounded edges or corners of a piece of wood, usually due to improper sawing or shaping. This can reduce the usable surface area of the board and affect its structural integrity. It is important to minimize wane to ensure the strength and quality of the lumber.
HF lumber stands for "hem-fir lumber," which is a type of softwood lumber typically made from a combination of western hemlock and true firs. It is commonly used in construction for framing and general building purposes due to its strength and versatility.
Quarter sawn lumber is often more expensive than flat sawn lumber due to the additional time and effort required to produce it. It is known for its distinct and desirable grain pattern, which many find more attractive and stable than that of flat sawn lumber.
To properly dispose of lumber, you can recycle it at a local recycling center, donate it to a construction reuse store, or use it for other projects around your home. Avoid burning treated lumber or dumping it in landfills to protect the environment.
The carbon footprint of a 2x4 lumber depends on various factors such as the type of wood, sourcing, processing, and transportation. On average, the production of lumber generates about 1.9 kg of CO2 per kg of wood. However, sustainable forestry practices and using local sources can help reduce the carbon footprint associated with 2x4 lumber.
Lumber and fuel burning is the rapid oxidation process of carbon. Thus its equation will be - C + O2 = CO2. However during this process due to increased temperature, a number of other elements present in lumber and fuel, also get oxidized.
