packaging, process & consumption wastes
DESCRIPTION
Class project on "Packaging, Process & Consumption Wastes" for Environmental Management course.TRANSCRIPT
Primary packaging is the wrapping or containers handled by the consumer
Secondary packaging is the term used to describe larger cases or boxes that are used to group quantities of primary packaged goods
Transit packaging groups into larger loads for transport, which facilitates loading and unloading of goods
Plastic packaging ofvarious types andplastic materials.
Glass bottles and jars Paper and cardboard wrapping and boxes Metal cans Wood
• In many countries, thin polyethene carrying bags are just thrown away. As they are not biodegradable, they pile
up, and then block drains and cause floods. During monsoon the city of Mumbai was flooded for days due to drainage
blocks.
• Therefore, the use of these bags (20 or 30 micrometer) has been
banned in many countries
• The main “method” of waste management in many countries
is open burning. If waste contains chlorine, dioxins and furans
are formed.
• Pre-consumer waste materials come directly from manufacturers.
• Postconsumer waste materials come from consumers, after they have used the product.
• Consumers include citizens, shops, offices, markets, hospitals
• Recyclable materials are mixed with other waste Recyclable materials include: paper, cardboard, glass and metal packaging, newspapers, food waste, garden trimmings
• Placing different waste materials into separate containers before they are thrown away together is called waste segregation at source.
• In order to be successful, the segregation system has to be convenient to waste generators (citizens and others).
• In addition, adequate and sufficient information and instructions should be provided, and active contribution of other stakeholders required.
• Waste generators (e.g. households and businesses) store their segregated waste materials
• Bring them to designated communal containers, drop off centers
• Give them to informal collectors• Bring them back to shops, as part of
producer responsibility system for beverage bottles (if supported by a deposit)
• Retailers take over discarded products as part of producer responsibility system
Most of the recycling today is actually Downcycling: in every new cycle material loses quality
Upcycling – 90% recycled PET
Direct heating (boiler house) Electricity production / combined heat
power Upgrading to natural gas quality
Materials used in products (and packaging) could successfully be reused again and again
Materials are biodegradable Pure in their chemical composition
Pollutant or a combination of pollutants discharged into the environment by manufacturing or production process from process industries.
The process industries includes chemical,pharmaceutical,biotechnology,food and drink,oil and gas,power generation and mineral sectors.
Process waste includes solid,liquid and gaseous wastes.
Ex:◦ Textile effluent waste.◦ waste from power generaion

Prevention Minimization Recycling Discharge
Waste management implies activity at a number of levels in the organisation◦ Company mangement (Investment proposals and
projects)◦ Research and Engineering◦ Production
Reducing process waste by increasing efficiency has two major imapct◦ Maximization of Profit◦ Better public relation value
The waste generated from the resources that society consumes are called as consumption wastes.
Mostly go for further recycling.

It consists of: packaging parts that are not needed, such as fruit skins,
bones in meat, etc. broken things, things no longer working, spoilt
food, worn-out clothes, clothes which no longer fit outgrown items toys, clothing, books, schoolwork disposables such as finished batteries, tissues human waste, waste of pets, waste water from
various forms of cleaning
