WASTES

-

 

Waste can be solid, liquid, or contain gaseous material that is discarded by disposal, recycling, burning or incineration. It can be a by-product of a manufacturing process or an obsolete commercial product that can no longer be used for its intended purpose and requires disposal. Inappropriate waste disposal practices can lead to contamination of ground water or potential fines and/or penalties as stipulated in national regulations.

Domestic waste, inert construction/demolition materials, metal scrap and empty containers are normally solid (non-hazardous) waste (except those historically used to hold hazardous materials that should be managed as hazardous materials), and residual waste from industrial operations.

Hazardous waste shares the properties of a hazardous material (such as ignitability, corrosivity, reactivity, or toxicity), or other physical, chemical, or biological characteristics that may pose a potential risk to human health or the environment if improperly managed. When a hazardous material is no longer usable for its original purpose and is intended for disposal, but still has hazardous properties, it is considered a hazardous waste. Typically, hazardous wastes include solvents, fuels, asbestos in building materials, PCB oils in electrical equipment, most pesticides, and ozone depleting substances in refrigeration systems. Wastes may also be defined as “hazardous” by local regulations or international conventions, based on the origin of the waste and its inclusion on hazardous waste lists or based on its characteristics. Hazardous wastes should always be segregated from nonhazardous wastes.

Islam is a religion with a strong distaste for wastage and using things beyond what is needed and necessary. This concept is illustrated in the following Quranic verse:“O you who believe! Make not unlawful the good things which Allah has made lawful for you, but commit no excess: for Allah loves not those given to excess.”(Quran 5:87)

Zero Hunger

REFLECTIVE JOURNAL Zero Hunger Wasting food become a daily habit of people nowadays especially in the city. When we visit the restaurant, we can see people around us leaving the table with leftovers on the dish. Even we ourselves do the same. We buy some drinks or food just because are intrigued of the packaging or the advertisement then throw it away when we do not like the taste. It is a terrible fact. According to Food and Agriculture Organization (FAO) data, every year 1.6 billion tons of food are wasted which 1.3 billion tons of it can actually still be consumed.

Quality Education

 REFLECTION JOURNAL  Quality Education As I belong to a culture which have a mindset that a girl doesn’t deserve to study university because in the end she belongs nowhere but “the kitchen”.  I have always dreamed to go aboard for educational purpose. And of course the whole folk wasn’t really convinced about that!  Some says “How come a girl go to college! It will be hard to find a husband for her” and others say “Why should we waste money? She will be a house wife anyways”  Well to be honest All that was expected. Thankfully, having an open minded parents helped me to overcome those spiritless speeches.  Quoting from UN poster “Education helps reduce inequalities and reach gen- der equality and is crucial to fostering tolerance and more peaceful societies.”  In my experience, I have lived in between and felt the impact of a woman having a high education, she is not only able to raise a well educated child but also gain respect from her husband an...
