Everything we use will influence in one way or another throughout all the processes that will occur. Therefore, we must take the precaution of never including toxic or harmful elements in the composting. The following list will facilitate the selection.
Organic compostable materials without problems
- Garden or garden plants
- Adventitious or bad herbs called "weeds", (better before they make seeds)
- Manure and poultry beds
- Crushed or chopped branches from pruning (up to about 3 centimeters thick)
- Kills and scrubs
- Medicinal plants
- Fallen leaves of trees and shrubs (avoiding those of walnut and royal laurel)
- Hay and mowed grass
- Lawn (in very thin layers and previously dried)
- Coins and remains of fruits and vegetables
- Organic food scraps in general
- Spoiled or expired foods
- Egg shells (better crushed)
- Coffee grounds (paper filters may be included)
- Remains of infusions (those that go in envelope if he)
- Napkins and tissues (not printed or colored); better recycle them
- Haircuts (not dyed)
- Raw wool or old mattresses (in small layers and mixed)
- Remains of wine, vinegar, beer or spirits
- Edible oils and fats (very scattered and in small quantities)
- Nutshells
Compostable materials with reservations or limitations
- Orange, citrus or pineapple skins (few and chopped)
- Remains of meat, fish, shellfish, their bone structures and shells
- Spoiled, rotten or sprouted potatoes
- Ashes (sprinkled and pre-moistened)
- Sawdust shavings (thin layers)
- Paper and cardboard (without printing color inks); better recycle them
- Natural fiber cloths and cloths (without mixing or acrylic dyes)
- Branches and leaves of yours and cypress (very few, chopped and pre-moistened)
Never add to compost
- Chemical-synthetic materials
- Non-degradable materials (glass, metals, plastics)
- Agglomerates or plywood of wood (nor its shavings or sawdust)
- Tobacco (cigars, cigars, sting), as it contains a potent biocide such as nicotine and various toxins
- Detergents, chlorinated products, antibiotics
For those interested in ecological composting, they should also avoid materials that may contain fungicides, herbicides and any type of pesticide because they always leave a trace.
