Forewords
Simona Tanning, as a social responsible company , produces environmental leather. We grasp every possibility to protect our living environment through reducing energy, water, solvent use and solid waste generation during processing.

Changes We MadeWATER
All treated water from MBR is going to RO system for treatment.
Build up rain water recycling system to collect rain water Use condensate system to reuse steam condensate as hot w
ithout steam heating again Reuse lab returning water Set up departmental production water consumption target Put departmental water consumption into staff KPI assessm
ent Attribute the hot water to employee area for taking bath and
sale extra condensation to the wood fired boiler.

Changes We MadeWATER
All treated water from MBR is going to RO system for treatment. The average RO water used for process was higher than 60% of total processing water needed of whole year.
![Page 6: Environmental Actions in 2009](https://reader035.vdocuments.site/reader035/viewer/2022062500/56815a17550346895dc760b2/html5/thumbnails/6.jpg)
Changes We MadeWATER
Build up rain water recycling system to collect rain water. The whole trial collecting area is 2448m2, according to the yearly rain in Huizhou of 1705MM that we can save about 4174m3 water a year.
![Page 7: Environmental Actions in 2009](https://reader035.vdocuments.site/reader035/viewer/2022062500/56815a17550346895dc760b2/html5/thumbnails/7.jpg)
Change We MadeWATER
Use condensate system to reuse steam condensate as hot water to reduce steam use for heating water.

Changes We MadeETP
Utilize Fenton system to treat concentrate MBR membranes replacement Install more aeration pipes in the old ETP Reduce the chemical adding in Fenton process Divide the second settlement tank into second settlement tank and biologi
cal settlement tank Fix sludge scrapper in the biological settlement tank Reedbeds treatment trial Move the air pipes the side of the facultative tank in the old ETP, which is
not only help to push water swirled and make sludge move but also good for taking out the broken aerator without pumping out all water.
Use submerge propeller instead of diving mixer in the balance tank in the new ETP that each one can save about 1kw/h.
Construct one more tank for planting Vertiver at Reedbed to get better trial result of effluent treatment.
Cancel some aerobic tanks in the new ETP. Utilize the REDOX DAF to replace the current DAF

nt Add heat isolating curtains on some machines to save steam u
sage Install heat isolating layers at the bottom of the tunnel for the r
oller coater to keep warm to reduce about 1/6 electricity usage. Utilize energy saving light tubes, save about 1/3-1/4 electricity
use. Utilize the separate switches to control steam supplying to the
