ABSTRACT

Background: The seafood industry produces over 100 million pounds of seashell was­te every year. With landfillspace diminishing quickly, ways to recycle waste ma­te­rials are becoming more sought. This happened in Cilincing, Indonesia. There were piles of green shell skin up to 2 to 4 meters. Green shell skin waste can be used as material to ma­ke paving block. It can be solution to handle green shell skin waste. This study aimed to analyze the contents and waste handling of green shell skin in Cilincing, North Jakarta.

Subjects and Method: This was a descriptive qualitative study conducted at Ci­lin­cing, North Jakarta. The study theme was contents and waste handling of green shell skin. The green shell skin waste was processed into paving blocks.

The strength test was done by dropping both green shell skin and ordinary paving block from 2 to 3 meters height.

Results: Green shell skin contained Calcium (36.7%). Processed green shell skin waste in­to paving block was an effective way to handling the waste. Both green shell skin and or­dinary paving blocks had the same strength.
