BTEC First Engineering 1: The Engineered World Unit 1: The Engineered World Reducing waste Reduce Reuse Engineers should think about using less materials and energy to manufacture products. If a product can be used again, this reduces the amount of materials going to landfill. Recover Recycle Waste materials can be treated to generate heat or power for other uses. Products can be broken down into materials that can then be re-manufactured to make new items. © Pearson Education Ltd 2012. Copying permitted for purchasing institution only.

BTEC First Engineering 1: The Engineered World Unit 1: The Engineered World Lean manufacturing Just-in-Time Kaizan Poka-yoke Materials and components are delivered to a production line when they are needed, thus reducing cost and time. Many well-planned manufacturing systems are based on Just-in-Time. To make things better, a company needs to improve continuously. Kaizan is a system where ideas that are suggested by workers that can be used to make production better. Mistakes often happen in engineering. Pokayoke is a method that can be used to eliminate human error where tasks are repeated. The benefit to staff is that jobs become less boring. © Pearson Education Ltd 2012.

BTEC First Engineering 1: The Engineered World Unit 1: The Engineered World Renewable sources of energy Wind Solar Turbines are used to convert wind energy into electricity. They cause no air or water pollution, but are only efficient when it is windy. Photovoltaic cells use the light of the sun to produce electricity. They work most efficiently when they are south-facing. Hydro Geothermal Moving water can be used to generate electricity via a turbine. The water can be stored in a reservoir to make sure there is always a supply. Steam naturally heated by the earth can be used to turn a turbine. This then generates electricity. There is no pollution from geothermal energy. © Pearson Education Ltd 2012. Copying permitted for purchasing institution only.
