Composting

The home composting allows citizens to use their organic waste in their own backyard or garden. This type of composting promotes the decomposition of organic waste per share of micro organisms, saving environmental costs (pollution) and economic aspects of transportation and disposal of such waste in landfills.

Should do the following steps for home composting:

1. Choosing the location of the composter

The composter should be placed in an easily accessible place during the year, with a mix of sun and shade, preferably on top of the ground, in permeable surface and under a leaf tree, which gives shade in the summer and sun in the winter.

2. Choice of composter
There are several types of composter on sale, as the rodent-proof composters. However, you can make your own composter, from a cardboard box of wood or plastic, with holes underneath, to prevent odours and to facilitate the entry of microorganisms.

3. Composting

Materials needed:

Organic materials
Water
Garden composters
Scissors (to reduce the size of the waste to be composed)
Rake (to rake the material for composting)
Thermometer
Watering can

The composite materials


Greens:
Remains of raw vegetables
Remains of fruit and barks
Coffee grounds, including filters
Rice and cooked pasta
Green leaves
Bags of tea Cereals herbs (without seeds)
Remains of cut grass and flowers

Crushed egg shells

Brown:
Hay
Straw
Wood chips and sawdust
Dried leaves Twigs

Materials not to composite:


Meat, fish, shellfish, dairy products and fats
Excrement of animals
Waste gardens treated with pesticides
Diseased plants or infested with insects
Ash from coal
Herbs with seeds
Textiles, paints, batteries, glass, metal, plastics, medicine, chemicals.

Rules of Separating


First of all, it is necessary to separate the materials recyclable. Then you must clean and check if there are no remains of product inside. You should squash the package to reduce space and facilitate its transport. Finally, if the package contains another type of material (for example the covers) should be removed. Now, just put the products in their containers.

Advantages of Recycling

The recycling of plastics brings some social and economic benefits to the society, highlighting the following:

• Reducing the volume of garbage collected that is removed to a landfill site, providing increased of life and lower costs of transport;
• economy of energy and oil, because plastics are derived from petroleum;
• create jobs, With reduction of social pressure;
• lower prices for the consumer of products produced with recycled plastic;
• notable improvements in the process of decomposition of organic material in landfills because the plastic waterproof layers of the material decomposed, hampering the movement of gases and liquids;
• contribution to the reduction of environmental degradation as a whole and forests, in particular, to replace wood and paper.

Curiosity about recycling



Daily, each of us is responsible for the production of about 1.3 kilograms of waste. At the end of the year are nearly 500 kg. of waste, 9% are plastic packages.

The energy saved by recycling a glass bottle is enough to keep a lamp of 100 watts lit for 4 hours.

For every ton of glass used in the manufacture of glass includes saving 1.2 tonnes of original-raw material.

One ton of recycled paper avoids the killing of 15 to 20 trees.

The production of recycled paper means saving water needed in the production of paper and reduces the cutting of trees, therefore contributing to a sustainable forest.

Five plastic bottles recycled lead to enough polyester to make a short-sleeve shirt in XL. For a pair of pants 10 bottles are enough, and 25 bottles provides material for a sweater.

Each 100 tonnes of recycled plastic prevents the extraction of a tonne of oil.

Due to the low weight, the use of plastics in cars reduces fuel consumption by 4%.

The recycling of plastics saves oil and natural gas, the two raw materials more used.



A can of a drink can be infinitely recycled without losing its quality.

Recycling one ton of wood waste prevents the killing of 40 trees.

One ton of recycled paper saves between 15 to 20 trees and in the production of this recycled paper are spent 2 to 3 times less energy.

The glass is completely recyclable, to obtain 1 ton of glass you simply need to recycle another ton.
