The Science Behind Biodegradability
Factors Influencing Biodegradability:
- Molecular structure of the finish
- Presence of natural enzymes
- Environmental conditions (moisture, temperature, microorganisms)
- UV exposure
DIY Biodegradable Finish Recipes
| Finish | Ingredients | Application | Durability |
|---|---|---|---|
| Beeswax polish | Beeswax, jojoba oil | Furniture, decorative items | Moderate, refresh regularly |
| Linseed oil-terpentine mix | Linseed oil, turpentine (1:1) | Floors, outdoor wood | Good, annual maintenance |
| Milk-lime paint | Cottage cheese, hydrated lime, water | Walls, untreated wood | Fair, reapply as needed |
| Oak leaf-iron finish | Oak leaves, iron filings, water | Graying effect on wood | Long-lasting, deepens over time |
