environmental burden in manufacturing. Complex products like semiconductors (Williams 2002) and cars are frequently subjected to life cycle assessments as a part of or in conjunction with environmental impact analyses. For conventional processes like sand casting such an evaluation is uncommon. Although sand casting has reached a stable
Before we get into the advantages and disadvantages of manufactured sand what exactly is manufactured sand? Manufactured sand is sand produced by crushing rocks quarry stones or larger aggregates pieces into sand-sized particles. Natural sand on the other hand is the naturally formed sand extracted from river beds. The Manufacturing Process
Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e. a soil containing more than 85 percent sand-sized particles by mass.

Sand and gravel are mined on a huge scale around the world. But few global data are collected on this activity. The United Nations Environment Program (UNEP) estimated that the total exceeds 40 billion tons a year. But its estimate had to be based on a proxy: cement manufacture.
Manufactured Sand (M Sand) Only sand manufactured by VSI crusher/Rotopactor is cubical and angular in shape. Sand made by other types of machines is flaky which is troublesome in working. The Jaw crushers are generally used for crushing stones in to metal/aggregates.
