Highly polluting industry – EPL ‘A’ category
Emission standards are published in gazette extraordinary No. 1534/18 of 01.02.2008
Polluting status of the Industry

Waste Generation&
Mitigation

Dissolved solids and dissolved aromatic compounds are present.
Passing though resin beds and activated carbon filtration is practiced
Hot water is re-used by cooling
Larger scale plastic collectors clean the materials separately now
Waste Water

Gaseous emission from machines during plastic heating process - Wet scrubbing, Using safety wears
Dust and particles – Better housekeeping
Gaseous Pollutants

Almost everything is re-used
Un re-usable matter will be sent to incineration.
Solid Waste
Noise & Vibrations Machines in operation - Enclose in a room to
avoid noise, dissemination; servicing and lubrication of machines
Vibration - Proper mounting of machinery

Plastic is melted during the recycling process, which causes it to break down and release the chemicals used to make it.
Recycling plastic is associated with skin and respiratory problems resulting from exposure to and inhalation of toxic fumes, especially hydrocarbons and residues released during the recycling process
Heating and reheating also degrades plastic
Issues With Plastic Recycling
![Page 21: Plastic Recycling in Sri Lanka](https://reader036.fdocuments.us/reader036/viewer/2022081605/58f9af68760da3da068bacd1/html5/thumbnails/21.jpg)
Small scale recyclers have low facilities for the treatment processes.
The production of ‘Virgin’ plastic cannot be reduced.
The environmental quality of the countries where new materials are made from recycled plastics will be degraded. (China, India and Malaysia)
![Page 22: Plastic Recycling in Sri Lanka](https://reader036.fdocuments.us/reader036/viewer/2022081605/58f9af68760da3da068bacd1/html5/thumbnails/22.jpg)
Waste segregation practices should be strictly followed in the country
The monitoring of the discharged waste water/air and solids by the recycling plant should be monitored frequently
The government should involve more effectively to the industry
Reduction of the use of plastics nationwide
More safety measures should be taken when handling the recycling process
Increasing the awareness among the public
