The document discusses the processes of landfilling and recycling waste. When waste is landfilled, it is compacted into cells at the landfill site and covered with soil or clay. A liner and drainage system prevents chemicals from leaking into the soil and methane is captured. In recycling, collected waste is sorted and taken to a recycling facility to be melted and molded into new items. Recycling is preferable to landfilling as it reduces greenhouse gas emissions, conserves raw materials, and uses less land over time.

Ceramics manufacture process, properties, uses and classification
It is most typically used as transparent glazing material in the building envelope, including windows in the external walls. Glass is also used for internal partitions and as an architectural feature. When used in buildings, glass is often of a safety type, which include reinforced, toughened and laminated glasses.

PART 1: Alternative building techniques- we use on site materials to keep costs low, sand or subsoil, 50% rice hull for high R walls, which requires a stabiliser. Pneumatic tampers can work also, moist clay and sand become in effect sandstone, no stabiliser needed, but less insulation.
The ppt is useful for basic information on Cement, glass & refactories.
All above materials are used as Civil engineering materials.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

4. What happens in a landfill? Waste arrives each day by lorry Waste is compacted into cells and covered in soil or clay Liner and drainage system stops chemicals leaking into soil Methane is piped away
10. Recycling Recycled Collected, sorted and taken to a recycling facility Melted Made into plastic flakes Moulded into new items
11. Landfill or Recycling Which is which and which is better? Adds greenhouse gasses to the atmosphere Uses space and land Requires more raw materials for new goods and products Reduces the space and land required Reduces greenhouse gas emissions Reduces raw material use Landfill Recycling
13. Steel Steel is made from iron ore which is found in some naturally occurring rocks. These rocks are mined and transported to factories to be melted in large furnaces to extract the metal. CLOSE
14. Aluminium Aluminium occurs in the earth’s crust as bauxite. Bauxite is a clay like rock which is mined and then refined; first into aluminium oxide and then into aluminium by electrolysis. CLOSE
15. Glass CLOSE Glass is made from the minerals sand, soda ash and limestone. These materials are extracted and transported to factories and melted together at very high temperatures.
16. Plastics CLOSE Plastics are made from crude oil which is formed by decaying plants and animals in seas that existed millions of years ago and is found under the ground. This crude oil is drilled out of the ground, transported to oil refineries for processing and taken on to factories to made into plastics. Example country: Saudi Arabia
17. Paper CLOSE Paper is made from cellulose fibres found in trees. These cellulose fibres are usually sourced from recovered waste paper, forest thinnings and sawmill residues that result from the furniture and construction industries. Papermakers then transport this material to their factories to be pulped into new paper based products.
