「由始至終」的化學廢物「運載紀錄」

在香港，處理化學廢物的所有過程皆由環境保護署監管。而一件化學廢物的整個生命週期，亦即從產生、收集、以至運送至收集點，都是根據香港法例第三五四章廢物處置條例所公布的廢物處置(化學廢物)(一般)規例所監管。

而廢物產生者、廢物收集者和終點處置設施都必須經由環保署發牌，而全個運送過程亦由環保署監管，須符合「由始至終」的化學廢物管理方式。


 「由始至終」的化學廢物管理方式

為了進一步減少非法傾銷和不恰當的棄置化學廢物，環保署更特別採用一套特別的「運載紀錄」系統。在產生和處置化學廢物前，化學廢物產生者需向環保署登記，登記以後，廢物產生者需要填寫一組稱為「運載紀錄」、一式三分的表格，才可委託合資格的化學廢物收集者，將化學廢物移離該處。根據這一制度，一式三分的「運載紀錄」，第一分副本將由廢物產生者保管、第二分副本將由廢物收集者在廢物運送至接收點後保管，而原本的存根則將由廢物接收點（處置設施）保存。



所有有關清理、處置以及運送化學廢物的活動，只可委託由環保署批准的合資格的持牌化學廢物收集者。而在收集廢物後，收集者必須在48小時內將廢物轉移到廢物接收點（處置設施）。

正昌是唯一通過ISO14001認證、而又可同時為廢物生產者提供一個一站式和最終解決方案的化學廢物收集者及接收設施。我們的業務範圍包括收集廢潤滑油、廢非鹵化溶劑、含油廢水、布碎、油隔、吉罐、廢油漆罐、光管及電池等固態化學廢物。正昌提供一站式的化學廢物處置服務，除了收集，我們更領有環保署簽發的化學廢物處置設置牌照，整個業務操作完全符合環保署的要求。

為使客戶安心，我們對「運載紀錄」系統極為重視，所有化學廢物的清理、處置以及運送活動都紀錄在案，亦保證所有的化學廢物將得到妥善處理，在我們位於元朗工業邨的化學廢物處理及回收中心，有用和可回收物料將經提取、分類後將再運送至各物料的回收中心。為增加透明度，我們亦會因應個別客戶的要求，供他們查閱「運載紀錄」。

 一式三分的「運載紀錄」︰白色為原本存根，由廢物處置設施保存；黃色為廢物收集者存根；粉紅色則為廢物產生者存根。

Proper storage of chemical waste

Under the Waste Disposal Ordinance (Cap.354) - Waste Disposal Regulations, Hong Kong Environmental Protection Department has defined chemical waste as any substance or thing being scrap material, effluent, or an unwanted substance or by-product arising from the application of or in the course of any process or trade activity, and which is or contains any substance or chemical specified in the prescribed schedule if such substance or chemical occurs in such form (http://www.epd.gov.hk/epd/english/environmentinhk/waste/guide_ref/files/guide_e.pdf), quantity or concentration so as to cause pollution, constitute a danger to health or risk of pollution to the environment.

Chemical waste should be properly and temporarily stored by the waste producer before the waste is transferred by the waste collector to a licensed treatment provider. There are certain criteria should be applied to the containers for temporary chemical waste storage, including its material, condition, etc. Such containers should be placed in a suitable area located close to the waste generation source for temporary storage and the containers should be either drums or jerricans type. The size of the containers should be determined according to the quantity and frequency of chemical waste to be stored. Common types of materials to be used for the containers include plastics and steel.

The storage area should be enclosed on at least three sides by partition, wall or fence with a height of not less than two metres or the total height of containers in stack, whichever is less. Such enclosures should be built with concrete, brick of steel with fixed erection to the areas. In addition, appropriate labeling should also be applied for accurate indication to ensure proper and safe handling, storage and transport of the waste.

Impacts of oil to us

Lubricants are used in many types of machinery during the day-to-day operation in various industrial and commercial activities. Used oil is, simply put, any oil that has been refined from crude oil and such use leads physical and/ or chemical contamination. During normal use, Impurities including dirt, metal particles, water, as well as other chemicals may be blended in with the oil, causing diminishing performance. These lubricating oils are classified as a type of chemical waste because it has been proven to have severe adverse impacts on the environment if dispose of improperly.

Chemistry of oil

Petroleum and its related products are made up with hydrocarbons, which are by its name, compounds containing both carbon and hydrogen. The simplest molecule of hydrocarbon is methane, the main component of natural gas. With the extension of additional carbon and hydrogen atoms, longer chains will be formed. In the case of lubricating oils, each molecule contains from 20 to 70 carbon atoms. These molecules are found to be particularly stable and will never be diminished. That is to say, replacing depleted additives within the oil is the key and crucial step to refine the used oil.

Impacts to environment and human health

Numerous toxic substances are found in spent oil, these toxins are uneasy to be degraded once enter the environment. For instance, polycyclic aromatic hydrocarbons found in used motor oil have been proven to be a carcinogen. Tiny metal scrapings from the engine compartment such as lead, arsenic, and zinc will also blended into the oils during operations. In addition, exposure to heat during engine combustion will also alter the chemical structures of the oil. Leakages, spillages, or improper handling of lubricating oils will enter the local water bodies unavoidably, through manmade drains or channels to streams, rivers, lakes, underground water tables and even reaching the ocean. At the end of the day, poisoning our drinking water sources and marine animals that we may consume ourselves.
