In our country, we collect and recycle batteries (white), glass (black), plastic (red), paper (blue) and cans (yellow). We also recycle used equipment and home appliances in special sections.
In our school we collect batteries, paper and cans. We don’t collect plastic bottles or glass.
Battery recycling aims to reduce the number of batteries being disposed as municipal solid waste. People are concerned about contamination, particularly of soil contamination and water pollution, by the addition of heavy metals and other toxic chemicals from batteries. Most types of batteries can be recycled. However, some batteries are recycled more readily than others, such as lead - acid automotive batteries (nearly 90% are recycled) and button cells (because of the value and toxicity of their chemicals).Other types, such as alkaline and rechargeable, can also be recycled.
Types of batteries
These batteries include but are not limited to: Car Batteries, Golf Cart Batteries, UPS Batteries, Industrial Fork-Lift Batteries, Motorcycle Batteries, and Commercial Batteries. These can be regular lead acid, sealed lead acid, Gel Type, or absorbent glass mat (AGM) batteries.These are recycled by pounding them, neutralizing the acid, and separating the polymers from the lead. The recovered materials are used in a variety of applications, including new batteries.
Silver Oxide Batteries
Used most frequently in watches, toys and some medical devices silver oxide batteries can become highly hazardous at the end of their useful life. After a period of use of approximately five years the batteries may begin to leak their contents which contains mercury, posing a serious health risk. The mercury will begin to corrode the inner shell of the battery. In most jurisdictions there exists legislation to regulate the appropriate handling and disposal of silver oxide batteries in order to minimize the risk to public health and the environment are recycled by shredding them and recovering the mercury.
Glass is very easy for recycling if it’s sorted. It should be sorted on: colo u r glass (green containers) and white glass (white containers). On the tip, the glass is sorted again. Next steps are crushing and cleaning of f labels. Than it’s melted in 1500 centigrade. From this is created new glassware.
Used tires are a type of waste, which most burdens natural environment.
They do not decompose, and because their storage requires large expanse on specially prefabricated area. In turn for fragmentation of the tires must disburse weighty amount of energy.
Material recycling aims to salvage material used to produce rubber. This process consists of two phazes – fragmentation and heat treatment. However, in result, sulfur isn’t removed out of rubber. Therefore obtained material is only of limited use. Only by-product tread tires is processed.
Salvage energetistic rely on burning whole tires, or after previous cutting. During combustion arise heat, which is use in process tochnological like the burning clinter in cement stoves or to produce steam in heat and power stations.
Plastic consists of various substances . M ost of them slowly spread and are harmful to people. S hopping bags or bottles of drink are made of plastic. Burning plastic is prohibited bec a use toxic gases are emitted into the atmosphere during combustion. However, they can be processed and reused. A lot of packs are made of plastic Shopping bags pollute our environment
We buy plastic bags or bottles. What happens to plastic after inserting into a suitable container ? Throw discarded plastics into suitable containers. They are sent to recycling companies There , they are processed in to such tubes , garbage cans or even fleece jumpers!
Aluminum alloys are alloys in which aluminum is the predominant metal. Typical alloying elements are copper, zinc, manganese, silicon, and magnesium. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminum is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al-Si, where the high levels of silicon (4-13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required .

Paper bag - the most common paper bag is produced from recycled paper.
We use them for shopping. It is environmentally friendly. Recently they have made colourful ones with eco - friendly paint.
I have asked fifty people about the environment. This questionnaire aimed to check how much people care about the environment through the implementation of simple daily activities.
People asked by me mostly answered ‘sometimes’. A lot of them use paper bags or other special bags when they go shopping. I t is encouraging that people have start ed to care about electricity in houses. It is very inportant because the climate is changing all the time . Still people forget about segregating waste, giving old drugs to pharmacy and collecting waste paper.
Medicines are substances that lead human to normal state. The most important in medicines is expiration date. If expiration date in drugs ends they will be very dangerous for body. We shuldn’t throw out drugs to rubbish bin because they can get to surface water and groundwater. Before you buy medicine you should check expiration date.
Where do we throw away medicine?
Usually out – dated medicines and boxes we throw to rubbish bin. This is a very bad solution. These medicines are dangerous wastes and they are bad for the environment. We should throw tyem into special containers, which are placed in some chemists’. Next they are recovered. Few people know that throwing out – dated medicine is prohibited.
A major appliance , or domestic appliance , is usually defined as a large machine which accomplishes some routine housekeeping task, which Include purposes such as cooking, food preservation, or cleaning, whether in a household, institutional, commercial or industrial setting.
1. Refrigeration equipment :
3. Washing equipment :
4. Miscellaneous :
Worn major appliance as light bulbs, computers, old televisons and radios, nonoperational refridgeratiers are in arrears on our cellars or lofts. What can We do with them? Answer look easy – to turf out them. But in practice this is not so simple. We should give back to due services point. Thats firms hand down theese WEEE ( W aste of E lectrical and E lectronic E quipment) to recycling process. Next WEEE disassemble for a machine elements and collect.
paper with foil paper (used in fax machines, the receipts)
beverage cartons and other food products
diapers, sanitary towels and other hygiene articles
building materials such as wallpaper, the plaster bags or cement, etc.
It is important that the waste is not wet - humidity is an important parameter of its quality - and that
together with paper you throw no mechanical impurities (eg metal, glass, textiles, sand), chemical (e . g . adhesives, paints), or microbial (mold and fungi).
The paper and its throughput ...
In t he twenty-first century, it is difficult to imagine functioning without paper. Average inhabitant of the world annually consumes about 50 kg of paper. Currently, the global annual production reaches 318 million tons. S uch a great number would be difficult to produce using only the raw material (wood).
Paper was invent ed by a Chinese , Caj Lun, who produced his first sheet in 105 AD from old fishing nets.
