Recycling Cans Could Help The Enviroment

Food and drinks cans make up around three percent of household waste that is thrown away by households in the UK on a daily basis. Around 75 percent of all drinks cans in the UK are made from aluminium although there are still almost 2 billion drinks cans that are made from steel. Food cans are often called tins because although they are made from steel, they have an ultra thin layer of tin that surrounds them.

If we consider that an average household goes through around 600 steel cans and 200 aluminium cans a year then it isnt hard to imagine the staggering amount of waste that is being generated by each and every one of us annually. We cannot go on burying this waste in landfill sites as the pressure on landfill sites is now nearing capacity and the estimations are that we will run out of space for new landfill sites within the next decade.

At the moment, approximately 80 percent of our household waste goes to landfill sites and as the amount of waste we produce is increasing each year we have to find new and creative ways of disposing of our waste. Landfill is no longer a viable option, not only because there isnt any space, but because landfill sites are not pleasant. There are risks associated with landfill that include the risk of explosion and also a risk of leakage of toxic pollutants into the surrounding earth and waterways which can present a health risk.

Basically, landfill sites are a threat to the environment so disposing of our waste in an environmentally friendly way that saves resources, energy and costs should be a matter of concern for all of us. Fortunately, more and more people are waking up to the idea of recycling. Local authorities also recognise the advantages of recycling and so roadside collections and the number of collection banks where you can deposit waste is on the increase.

Why recycle cans

Cans are one of the easiest items to recycle and the fact is, each and every can that ends up in landfill is a waste of a valuable resource and heres why. Producing new metal to make new cans depletes the earth of natural resources, such as iron, coal and water to make steel and bauxite to make aluminium and basically it costs more to produce new metal than it does to recycle it.

For example, recycling aluminium not only uses 95 percent less energy than it does to produce new aluminium if we recycle just 1kg of aluminium it saves 6kg of Bauxite. Similarly, if we recycle 1 tonne of steel it saves 1.5 tonnes of iron ore, half a tonne of coal, and uses 75 percent less energy than it does to make new steel. Recycling any type of metal reduces the CO2 emissions released into the atmosphere, reduces water pollution and massively reduces costs in general.

Cans are also 100 percent recyclable and can be recycled almost indefinitely without any loss of quality to the metal itself. Recycling metal is also a relatively simple process, in fact; it can take as little as six weeks for aluminium cans to be back on the supermarket shelves after collection.

One of the barriers to recycling other materials is the demand for the product. Take plastic for example; it can be cheaper to produce new plastic than to recycle it so there is less of a demand for used plastic. However, there is a great demand for used metal, so much so that there are schemes in operation that will pay you cash for your used aluminium cans.

Another barrier is sorting the waste. Sorting broken bits of glass can be a complex process but sorting aluminium from steel is not difficult. You can tell the difference between aluminium and steel using a simple magnet. If it sticks it is steel, which makes separation of steel very easy as magnets can be used to extract it.

So bearing in mind all the advantages involved in recycling cans, why are any food or drinks cans still ending up in landfill?

How you can make a difference

The truth is that we can all do more to protect the environment if we remember that each can dumped in landfill is a real waste. You can make a difference at home and at work by making sure that your cans are recycled and are not disposed of along with other rubbish. If kerbside collection is not available in your area yet, find out where the nearest collection bank or collection scheme is and deposit your cans there. If we all do our bit we can all benefit from a healthier environment and can preserve the earths resources for future generations.
