Everyday wastes are being produced by us either by household or industrial. The waste itself has the category and phase. Most of human being might be thinking that industrial waste has the huge impact to the environment rather than household waste. However, this article will show that perception slightly not right to say. This is because of the way of disposing it. In this article, different types of waste such as waste gas (gas effluent), waste water, and solid waste will be covered which is really crucial when managing waste.

Waste gas or more commonly known as gas effluent or the waste produced in gas or vapor form from industry mainly and very little portion from household. There are bunch of gaseous that being monitored before it is discharged to the environment such as carbon oxide (COX), NOX, sulfur oxide (SOX), particulate matter, volatile organic compounds (VOCs), hydrogen sulfide (H2S), etc. Beware also there is also potential of harm our household sewage line that releasing hydrogen sulfide which can cause fatality. This has happened even not in house but in living quarters of ship which shows that there is tendency to occur since there function only deals with sewage system. Besides these direct releases, there are also volatile organic compound is being released from solid waste disposal which releases methane from the anaerobic reaction. There is commercial approach is being practiced to monetize the methane but so far people generally not really interested yet to monetize it since it is not really profitable enough.

Waste water generally covers most of the industry and also household effluent after the treated water has been used. Again in industrial waste there are experts working on it to come out with latest technology to minimize the impact to the environment. Whereby, lack of awareness in household application, the effluent for water is discharged to common drainage system which not really measures the containment of anything that can impact the environment. For example, used cooking oil will drained together with used water in sink which can cause troublesome to the whole line. If noticed, all these happening because of the lack enforcement of the law for the residential area. However, for those thinking that industrial can cause harm the environment are the one actually treating the effluent before it is discharge. In fact, the effluents are treated step by step to achieve all the parameters as regulated by the regulatory bodies. There are couples of elements to be covered when treating the waste water such BOD, COD, suspended solids, temperature, etc. There are guidelines to be followed by the industry but none of guideline is given to household.

Now come to solid waste where this is the ultimate waste that would come if gas and/or water are treated. As for solid waste, the waste can be easily monetized if the good practice can be practiced from the beginning of throwing the waste/rubbish to the dustbins. And again it comes from our awareness to implement it. Nowadays lot of campaigns can be seen everywhere to throw the rubbish into different dustbins so that the garbage already segregated before it is collected. Besides that the categorized can be categorized straight away such as paper, plastic, etc. In addition to direct monetization, there is also direct monetization as highlighted above such methane gas produced from solid waste landfill.
