-
Steel is durable and hard-wearing.
-
Though steel has high carbon emissions during production, it can be
kept in the 'recycling - loop' so that it won't go to landfill sites.
It can be recycled continuously without loosing quality.
-
Steel paint tins only need to be
cleaned before they can be recycled.
-
Using recycled steel saves 75% of CO2 emissions and 75% of the energy
needed to make steel from virgin materials.
-
Steel is much stronger than aluminium. It has the highest strength to
weight ratio of any building material.
-
All steel cans contain a minimum 25% recycled content. The remaining
75% recycled steel is used around the world for construction of
bridges, automobiles, as well as wind turbines.
-
1.8 billion drinks cans are made of steel
-
Steel can, however, easily rust if the paint container has not been
sealed properly after use.
-
Unlike aluminium, steel is prone to corrosion.
Personal thoughts:
From
my research, I have discovered that aluminium is more eco-friendly
than steel. Every tonne of aluminium recycled saves 9 tonnes of CO2
emissions, 95% of the energy needed to make aluminium from virgin
material and 95% of greenhouse gas emissions. Recycled steel, though
still very much so profitable to the environment, saves at the most 75% the
energy needed to make aluminium from virgin material and 75% of
greenhouse gas emissions
Aluminium,
as a light, thin product, would also be more suitable for a paint
container, as it will be easier to carry and transportation would be
easier.
