From trash to treasure – turning plastic waste into biodegradable polymers using bacteria

TRASH OR TREASURE?: Putting Coal Combustion Waste to Work

The Springdale Pit, a former surface mine in Tamaqua, Pennsylvania, is used to store coal combustion waste produced by power plants in Pennsylvania, New Jersey, and New York. When states rule that minefilling is a " beneficial use " of CCW, it is exempt from environmental safeguards that would be applied to disposal sites.

Microwaves and microbes turn household waste into biodegradable plastic

Residuals: Trash or Treasure?

One of the significant challenges to the successful teaching of statistics is that of giving the topic some relevant historical perspective. Such an effort is worthwhile because many students need a context within which they can understand why we are studying a given technique and how that technique came about. In fact, many of our traditional statistical procedures can be associated with speci...

Turning Waste into By-Product

This paper studies how the conversion of a waste stream into a useful and saleable by-product affects a firm’s optimal operating strategy. We determine whether local implementation can be optimal, i.e., continuing business-as-usual to produce the original product and merely converting the collaterally generated waste stream into by-product, or whether global implementation – that re-optimizes t...

Turning waste to wealth-biodegradable plastics polyhydroxyalkanoates from palm oil mill effluent – a Malaysian perspective

Palm oil industries have been contributing significantly towards the country’s economy and increase standard of living among Malaysians. However, it has also been identified as the major contributor for discharging the largest pollution load throughout the country. Owing to high biochemical oxygen demand (BOD) and chemical oxygen demand (COD), the palm oil mill effluent (POME) cannot be dischar...
