Answer:
1.
1) Blue coloured bins are used for collecting materials that are recyclable. The recyclable materials include paper- newspaper, magazines, etc., cardboard, food tins, glass bottles and jars, plastic bottles, tetra pack packaging, etc.
2) The green bins are used for collecting kitchen and other plant or animal wastes. This type of waste rots completely when buried in the soil. It includes wastes like plate scrapings, vegetable peelings, meat and bones, cooked and uncooked food, cut flowers, etc.

A landfill is a low lying open site for the disposal of waste materials by burial and the oldest form of waste treatment. The various types of wastes accepted at landfills for disposal are household wastes (decomposable or non decomposable), construction and demolition waste with light contaminants, tree and yard trimmings etc.
3. Chemical elements
An element is a chemical substance made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element, though it can be transmuted into another element through a nuclear reaction.
4. The most common types of waste produced by an office
Paper
On average, 60-80% of office waste produced by businesses is paper. Some paper waste is inevitable, but much of it can be avoided.
Recycling paper waste can be done easily by installing recycling bins in your office, and making sure that employees are using these bins.
Furniture
In the interest of maintaining a modern, comfortable and functional office space, desks, storage and chairs often quickly become obsolete. They may lie around the office gathering dust, or may be thrown away with landfill.
E-Waste
We dispose of computers, phones, printers and other electronic items at a critical rate.
It’s so important that these items are being disposed of and recycled appropriately and responsibly. This is because the chemicals, metals and other materials that they contain are harmful to the environment. As well as that, much of the material can be reused.
Printing Products
Each year around the world, 350 million printer cartridges are thrown away, having an enormous impact on the environment.
Many print manufacturers offer a recycling scheme and pick up the used cartridges and toners directly from your office.
Plastics
Single use bottles, plastic wrapping and cups are all common items found in our office bins.
