The three main categories of garbage are organic waste (biodegradable materials like food scraps), recyclable waste (materials like paper, glass, and plastic that can be processed and re-used), and non-recyclable waste (items that cannot be recycled or composted and must be disposed of in landfills).

Three examples of biomass materials include wood chips, agricultural residue (such as corn stover or straw), and animal waste (such as manure). These materials can be used to generate energy through processes like combustion, gasification, or anaerobic digestion.
They are known as sedimentary rocks: limestone, chalk and slate are three examples.
Baking soda, household ammonia, and soap are common materials with a pH of more than seven.

Copper, aluminum, and gold are examples of good conductors of electricity.
Composted manure of any farm animal is manure that has been composted properly for the amount of time necessary to completely break down the material into it's basic organic components. Composted material is best identified by sight and touch: It is black, loose, crumbly, moist and has no smell to speak of. How long it takes to compost manure, or any other organic material, depends on the mixtutre of materials in the pile, moisture, aeration (turned piles compost much faster) and temperature. In a well maintained compost pile in summertime, complete composting can take place in as little as six weeks. When farmers spread horse manure "raw" on a field, they are assuming it will have three to six months breakdown time before that field is planted.
iron , cobalt and nickel are good magnetic materials. ------------------------------------------------------- Fe Co Ni. ie Ferrous, Cobalt and Nickel are the three ferro magnetic materials. It is better to say as rhyming with Marconi. FECONI. One more important secret is Ferrous is having 26 as its atomic number, Co 27 and Ni 28. All the three are neighbours being seated in the periodic table.
