Anggota Milist PB Yth.
Ada sebuah pabrik casting (peleburan & pencetakan) alumunium yang mempunyai
limbah dross dan shot blasting yang berasal dari furnace peleburan
alumunium. Limbah ini merupakan hasil samping dari kegiatan peleburan dan
pencetakan alat logam dr bahan alumunium.
Apakah ada diantara anggota milist yang memiliki cara daur ulang atau
recovery atau penanganan yang lebih ramah lingkungan ?.
saat ini limbah tersebut hanya dibuang atau dijual ke pihak
"pelapak/madura" besi bekas yang katanya bisa diproses kembali utk diambil
alumuniumnya (hanya sekitar 10-15% saja). ada juga info yang menyatakan
bisa diolah menjadi PAC (alumunium sulfat) bahan kimia utk penjernih air.
mohon bantuannya.
Toto
