Using fire-retardant materials
There are many advantages to using recycled building materials. First, using recycled building materials is good for the environment and helps to save natural resources. Secondly, the cost of recycled building materials is usually less than buying them new.
The majority of sanitary paper products are made from pulp or paper, though a significant percentage are made using the "nonwoven" process in which natural or synthetic fibers are bonded together by cohesion, friction, or adhesion.
Using synthetic materials, are less expensive for the suppliers to buy.
No you csn't machine the material which are non conductive by using edm.But there is a drived machining process which is used for machining non-conducting material(like ceramics, brittle materials) is ECDM(Electro Chemical Discharge Machining).
recycling means taking materials from old discarded materials and making other new products from them http://www.benefits-of-recycling.com/recyclingforkids.html
observation-it is a process of using your senses with or without materials by observing a specific things you want to discover.
Recycled does not necessarily mean a better product but by re-using materials that would otherwise go to landfills or by using less raw materials (like trees or oils), it is better for the environment. Recycled materials use less energy to process, too--saving resources and putting less greenhouse gases in the air.

Manufacture refers to the process of producing goods or products on a large scale, typically in a factory setting using machinery and labor. This process involves converting raw materials or components into finished products through various stages of production.
Primary Manufacturing is taking raw materials (from Primary Industry) and using them to make industrial materials. Then, these would go under another process called Secondary Manufacturing that uses these products and turn them into finished goods.Ex: trees > wood > lumber > chair
