Try to generate less waste and separate it for recycling. A good tip is also to adopt a compost bin for organic waste. When disposed of in landfills, solid waste that could be reused, for example, emits greenhouse gases, mainly methane. The generation of this gas occurs because the organic matter present in the waste, in a situation of absence of oxygen, favors the action of bacteria that decompose it, producing methane - which impacts on global warming. Recycling materials such as paper, glass, plastic and aluminum contributes to the saving of natural resources, through the use of recycled raw material instead of its virgin extraction and the reduction of expenses with extraction of raw material and its processing. Production from recycling uses less electricity and reduces the emission of greenhouse gases. Buying products made with recycled or recyclable materials helps to combat waste and global warming.
