HAZARDOUS WASTE MANAGMENT
NASIHA SAKINAH BINTI SAADON_2016249978_EH2208F
overview status in Malaysia
Industry and economic growth development
industries sector initially consist of oil refining, machinery assembly and light industries.
in 1970 and 1980 manufacturing in Malaysia boosted by extensive growth of electric assembly and electronic sector
late 1980, started exporting Proton to international market
1990, further growth on electronic such as semiconductors, silicon wafers
industries sector anticipted to contributed 37.2% overall GDP
equipped policies and stratrgies estabish by federal and state governement
number factories increasing
large population growth
Hazardous waste in Malaysia
consist of diverse set material in form solid, liquid, semi-solid
waste characteristics, ignitability, corrosivity, reactivity or toxicity
Hazardous waste contain one or more properties that pose danger to health and environment
classified as schedule waste if include in 77 categories of hazardous waste in
First Schedule of Environmental Quality ( Schedule Wastes), Regulation, 2005
main problem hazardous waste
illegal dumping of schedule wastes
types:
waste paint
mineral oils
dross
carried out in secluded area
factoired buried their waste
carried out by illegal factories
unliciense transporter
status of spent batteries and E-waste
main sources:
various electronic device applied
two major reasons E- waste become serious environment and health challenge
generate at alarming rate
additional waste (mobile phone)
computers contain heavy metal such as lead, chromium and mercury
contain component such as accumulators, mercury switches, glass from cathode-ray tube, polychlorinate biphenyl capacitor or contaminate with lead, nickel chromium
first schedule
includes battey contain mercury, lead, nickel and cadmium
propose strategies
recovery/ reuse of wastes
reprocess any waste that could utilised
improve disposal technologies
contaminated land
land containg contaminant that whenpresent in sufficient concentration may cause harm
found in workshop, petrol station, railway yard
generate spent diesel, lube oil, hydrocarbon
effect metal and chemical
landfill- contaminatr groundwater
waster- contaninate surface water, drinking water quality
enforcement
more officer shoul be recruited
improve organising team by involve policy, local councils
cooperation between government department
conter measures
setting up of intelligence unit to gather information
supportttools such as satellite monitoring system
audits on waste generators, recucle and disposal facilities
programmes develop national criteria and standard for hazardouswste
strengthen the hazardous waste management policy
design action plan
overall policy system and national framework
disposal of hazardous waste
most problem illegal dumping cause by indiscriminate toxic waste disposal
negative attitude of multinational companies
waste Code is limited. only 15 waste code allowes such as SW103,SW104,SW110
overview status in Malaysia (continued)
trend in hazardous waste distribution characteristics and production in Malaysia
largest quantities in Penang, Selangor, Johor,Perak
highest quantitiy in 1996 with 632,521 tonnes
due to remaining waste accumulate and not deliver to disposal
main wate include sludege, mineral sludge, metal dross follows by oil an hydrocarbon waste
55-58% wil be recycle at the off site local SWRF
65-90% reused at SWRF process plant
10-35% as waste residue
Brief Issues in handling current hazardous waste
Federal policy has directed towards several problem
develop sysytem to manage the storage,transportation,disposal
develop set of standard treatment, storage, recovery waste
define/identify/classify/quantify type of toxic and hazardous waste
establishing permit system
regulation standard and policy system for managmeent hazardous waste
Environent Quality (Schedule Wastes) Regulation 2005 (amendment 1989)
define that schedule waste as any wate falling under categories waste list in first schedule
key provision focus
control wate generae by notification system
avoid/minimise waste generation
safe storage of waste
lecensing of schedule waste facilites
treatment and disposal waste premise
-implement manifest system for track and control waste
