Traditional way - corrective control (end of pipe) Natural Resource Products waste Ambiance

Corrective control technology:
There was great environmental improvement (Ex: At the 80´s: Cubatão, the “Death Valley”);
CETESB and industries have been focused on;
It’ll be always necessary.
Emissions 1983(t/year) 2004(t/year)
MP 363,372 3,829
Fluoride 5,677 215
NH 3 3,489 15
Organic load 17,147 1,289

However , corrective controls model:
1. needs high cost (industries);
2. can produce some conflicts with environmental agency/ image impairment;
3. pollutant transfer: always needs final disposal;
4. is not enough to be in conformity with laws (many cases);
5. do not consider natural resources shortage;
6. production is more important than productivity.

Cleaner Production
In CETESB since 1992 (USEPA cooperation);
Focused on partnerships (sector approach);
Action on environmental problems sources;
Diverse actions
( guidelines and reports; pilot projects; successful cases; etc)
“ Pollution is often a form of economic waste” Michael Porter e Claas van der Linde

At the 90’s : new management industrial concepts
(total quality management)
Productive process revision;
Targeting efficiency production;
Waste generation means the process converts raw material into products inefficiently
Cleaner Production concepts begins

Cleaner Production; What does it mean ?
Use reduction on raw material, water, energy, etc.;
Selection of raw material (low toxicity);
Minimize waste in the production process;
Process to get it more efficient . Produce more applying less , Productivity increase ($$$) X environmental impacts reduction

Material which passed into the process and has consumed:
Inputs (water, energy, etc);
Raw material;
Equipments use;
Workforce;
Management costs increased by waste;
BUT do not turn on products, i.e.:
DO NOT BRING ADDITIONAL VALUE TO THE PRODUCT
What are pollutants?

Personnel training Energy and water consumption Water treatment and destination Product life cycle Real cost of waste it seems to be an Iceberg. Market Product quality Law conformity Toxic raw material use Preventive maintenance Lost data Toxic waste

CP industrial guides : Graphic, jewelry, tannery, Cosmetics and hygiene; paper and mill; slaughter; pottery; industrialized meat; etc.
