I’m sharing the step-by-step photos of a 100 liter composter that can be used in homes.
You will need: 100 liter plastic bottle with faucet; mosquito net (1m); hinge, 6 bolts, 6 washers and 6 nuts for the fertilizer catching door; scissor, stiletto, drill, saw-glass; expanded clay.
What you can put in the compost:

• Green leaves, grass, flowers

• Residues of fruit and vegetable
• Remains of bread crumbs, cookies, cereals
• Remains of cooked grains, flour, pasta and rice
• Coffee eraser (including dishwasher), tea bags …
• Manure of cattle, pigs, goats, sheep and chickens
MARRONS (rich in carbon)
• Sawing of wood, branches and bark of trees
• Cardboard, Newsprint

• Cardboard boxes, cardboard, napkins

How to compost::
1. The place to install the composter: If it is possible, place the composter near the kitchen; so the disposal of leftover food becomes easier. It is important that it stays in an airy and shaded place, for example under a tree.
2. Materials to compost: Collect and mix suitable green and brown materials for composting. We should have twice as many brown elements as green ones. Add a little bit of sawdust, dry straw, dry leaf or cardboard to the compost each day as a cover, leaving the green materials underneath.
3. Controlling the composting process: In order to develop well, the microorganisms need adequate conditions of scouring, humidity and temperature. The organic remains should be moist but not wet. If the material becomes very dry we will put some water. We should stir the material once or twice a week to allow sandblasting. We must control so that the temperature does not exceed 70 degrees. If it does, scrape the materials.
4. How to know if the compost is ready? At the end the compost should have an aspect which can not distinguish the types of material. It should have the dark color and smell of earth. When we rub on our hands, they do not get dirty. The process takes on average 2 months.
5. The slurry, or biofertilizer, can be used to combat pests in the garden. Just dilute the biofertilizer. There are 20 parts of water for a part of biofertilizer.
