The reason is that the theory of mechanics of materials is used in Drilling-Hole-Loading method.
Drilling-Hole-Loading method can also applied to measure tensile strength of small irregular brittle materials.

Because many biological ecosystems function successfully in recycling resources, so do industries function in recycling materials and renewing energies.
A few of the eco-industrial parks have tried and succeeded in green manufacturing and recycling in materials and energy.
The program should deal with pollutant abatement and eco-design for recycling and retiring of materials and products, process as well as energy-saving.

Introduction The municipal solid waste contains materials which vary widely in size, moisture, and nutrient content, and organic fractions of solid waste can be mixed with varying degrees of non-compostable wastes and possibly hazardous constituents.
Methodology Municipal solid waste was collected from Faculty of Science and Technology for the composting process.
