Wastewater• 97% Of Waste Water Discharged Without
Any Treatment

Solid Waste(Garbage)• Solid Waste Was Treated Into Dumping On
Public Landfill• (0.45 kg per person-day) or 800,000 kg /day
• PET bottle or plastic (PP) waste are mostly
recycled and reused as plastic seed by small
and medium enterprises (SMEs) , 40 % totalof garbage

DUE TO COMPLIANCE TO
GOVERNMENT RULESNO AWARENESS TOENVIRONMENTALRESPONSIBILITYENVIRONMENTAL Regulation and Rules in Indonesia , such as :-Laws No.32/ 2009 : Enviromnetal Protection & Management- Goverment Regulation No. 101/2014 : Hazardouz Waste Management- Ministry Regulation No.3 /2008 : Utilization Procedure of Hazardous Waste

Industrial Waste Management
1. Gas Emission
Some industries discharge their waste to environment directly.
However other industry apply stack equipped with air pollution
control like : scrubber, cyclone, EP.

2. Waste water
There are various charactheristic wastewater depend on typicalindustry. Wastewater can be treated by physical, chemical, andbiology technology.

3. Solid waste
Solid waste are classified as Toxic And Hazardous Waste Managed
By Other Specific Company and treated into Dumping, Incineration,and Reuse. Few industries manage their solid waste directly byincineration (Special permission is required).

SMALL AND MEDIUMENTERPRISES (SMEs)
Waste management is almost neglected,
because :• No awareness to protect the environment• No competency in WWTP operation• No space available to construct WWTP
• No knowledge about waste management• No competency in WWTP operation
Need Technical Guidance and Financial support from Goverment

Environmental issues
There are many kind of SMEs, mainly Batik (textile) and Tofu
industries.
Tofu is a famous food forIndonesian
Batik is intangible culture
heritage of humanity byUNESCO

Note :• Total number of Batik and Tofu are 47.750 unit and 115.000 unit, inIndonesia• Total number of batik and Tofu SMEs in Central Java are 25.500 unit
and 5.800 units• Total number of batik and tofu in Semarang are 25 unit and 67 unit.

Batik and tofu waste water become a problem for environmentWastewater characteristics
of batik and tofu industries- High pollutant loading : COD, BOD, TSS- High volume : 20 liter/ kg soy bean
 8 liter / meter textile
Still no appropriate technology forwastewater treatment. Existing technologies
mainly generate solid waste, needchemicals and spacious land.

Waste Management projectof CIPPT• Batik wastewater treatment using biology
processes ( anaerob and aerob ), still on
trial.
Demonstrated in one of SMEs in Semarang.
• Tofu wastewater treatment is still onprogress.
• RECP joint programme with UNIDO
Indonesia, will be executed on November
2016 in Semarang.
