Cleaner Production: A tool for Green Competitiveness in the Turkish Industry Ch 6. GENERAL CP OPTIONS Middle East Technical University Department of Environmental Engineering Workshop Series 31 March-2 April 2008 Ankara, Turkey
Objectives Details main CP options • Good Practices that the entire industrial plant must follow • Process operations, from the loading and transfer of raw materials to the unloading of products • Maintenance of equipments and installations • The switch from one material to less toxic materials • More specific aspects such as the selection of alternative solvents
Good environmental practices http://www.cprac.org/pdf/estudis/guies/BPA_En.pdf
Good environmental practices • Large amount of waste produced in the form of pieces of metal rail and faulty plastic parts. Definition of objective: • 100% recycling of plastic waste from the injection operation • sell the metal waste externally. • to separate the metal from the plastic and classify it correctly. It has been decided to: • separate the waste in the selective collection containers • verify that there are no defective rails in the banal waste container. The assembly operator will be responsible for BEPs and will monitor the selective collection containers and the banal containers after each shift. A supervisor will check that the BEPs is being applied in case the rails incorrectly classified need to be reprocessed. The personnel involved will require prior training. Assessment of the BEPs application will be carried out by keeping a daily production report.
The human factor • the following can be applied to the operation area and to any other area: • A good capacity building and training of operators is required in the activities they are involved in. • The operators must be well informed about why the operations will be carried out and the inconveniences that may arise if they are not implemented correctly. • The operators must understand that these difficulties may start by affecting their physical integrity and health, and then the nearby community and also the environment. • A good training must be completed with permanent communication between operators and supervisors.
CP options • Process and maintenance areas • Operations • Transfers • Maintenance • Supplies management • Purchasing • Storage • Packaging • Changes in materials • General • Toxic substances • Solvents Excercise 1
Use of solvents • In order to avoid or reduce negative environmental impacts that are linked to the use of solvents, a major part of CP in some industries incorporates the eco-efficient management of solvents. • A solvent management system includes the following: • Inventory of the types, applications and amounts consumed in the company • What cost they represent • Emission sources and capture or destruction systems • Measurement and quantification of emissions and retentions • Situation in relation to the regulation • Updating of records • Assessment of improvement options • Selection of appropriate options
Use of solvents Themanagement of solventsis a processtoimprovetheunderstandingonhow and why a company uses solvents and howit can control and reduce itsconsumption of solvents and associated VOC emissions.
Use of solvents • Following are someimprovementoperations: • A switchtoaqueoussolvents • A switchtootherorganicsolvents • Improved use and control of emissions • Improved capture of emissionsfromtanks and equipment • Internalrecycling • Externalrecycling • A structured and systematicmanagementsystem can bepart of a CPprogramme, a separateactivityorpart of a complete EMS. • Formanycompanies, theincreasingcost of solventsis as good a reasonforimplementingCP as forcomplyingwithenvironmentalrequirementsthat are more and more restrictivewithVOCs.
Non-standard CP Solutions The manuals do not always offer solutions that are non-standard or that can be applied directly. It is often necessary to find original solutions or adopt decisions that are not at all simple. The evaluator needs to have a general knowledge of the methodology for solving problems and adopting decisions, applicable to CP, the same as for any other area of technology management. He can, for instance, adopt the system proposed by Edward Deming for the industrial quality area, that consists of the following steps: Planning, Acting, Checking and Reviewing (PACR). Let’s have a look to the book….
