Do we actually realise the extent to which we waste?

Overview

Humans tend to waste a lot of resources, materials and other elements that don't have a physical form (time, for example). In this page I'm going to look at exactly what sort of things we throw away narrowing my focus on the Construction Industry to see what Architects,Contractors and Designers in general, waste.

What do Humans Waste?

  • Food;
  • Wrappers, bottles, packaging;
  • Glass;
  • Water;
  • Time;
  • Money;
  • Fuel.

It is estimated that each year up to 420,000 tonnes of waste wood is produced by households. 

Packaging (Pallets and crates) produce a further 670,000 tonnes, and construction and demolition 750,000 tonnes.

Water
  • On average, each person in a household uses 140 litres of water per day
Electricity
  • The whole of the UK uses 345,798,000 kWH of electricity  which is only 2% of the entire wolrds yearly comsumption
  • However the UK’s population is only 0.9% of the world.
  • An average amily with two children uses 5,480 kWh of electricity
Gas
  • A typical 3 bedroom house uses 25,000 kWh of gas a year

With the garbage produced in America alone, you could form a line of filled-up garbage trucks and reach the moon


Waste in the Construction Industry

Picture
Construction waste consists of any unwanted material produced by the construction industry.

It can include:
  • Brick;
  • Concrete;
  • Wood (damaged or unused, in the form of offcuts);
  • Rubble;
  • Insulation;
  • Nails;
  • Electrical Wiring;
  • Waste originating from the site;
  • Asbestos;
  • Hazardous Substances;





  • The construction industry has a major impact on the environment, both in terms of the resources it consumes and the waste it produces. The waste produced varies at each stage of the construction process. 


  • Over 90% of non-energy resources in the UK are used by the Construction Industry

Research has shown that up to 15% of building materials that go into a construction site are wasted!
  • This could be due to the "over ordering" culture that has a grip on the Construction Industry. This has emerged due to lack of communication between the different elements in the building process. If everybody talked to each other then more accurate stock levels could be ordered therefore reducing waste. 

With estimates hinting that the UK's existing landfill sites could be full in as little as six years,the construction industry must accelerate progress in order to help reduce waste.
There is the potential to recycle many elements of construction waste - Often roll-off containers are used to transport the waste. Rubble can be crushed and reused in construction projects. Waste wood can also be recovered and recycled

Domestic refuse accounts for only 10% of total waste in the UK, while the mountain of waste from construction remains a peripheral issue in comparison.


The Waste and Resources Action Programme (Wrap) estimates that this results in 13 million tonnes of fresh materials being thrown away every year. If we were more careful with what we waste on the construction site, millions of pounds could be saved, lowering the cost of building opening up so many more opportunities to develop.

The waste a building site makes in a week is enough to fill a container 1000 cubic metres in size
