Group 4 Flashcards
g involves turning raw ingredients
like petroleum or natural gas into polymers that may be
moulded or sculpted into a variety of shapes
Plastic manufacturing
The primary raw material used to manufacture plastics
petroleum
The production and transportation of plastic products and the
disposal of plastic waste can contribute to
carbon emissions
can take the form of solid materials like discarded
material and packaging, as well as hazardous waste like
chemicals and by-products
waste
Ocean litter has been identified and quantified in the four marine habitats
beach, ocean bottom, ocean water column, and ocean surface
designed to accept solid debris and
prevent contamination of the land and groundwater
from the solid debris.
landfills
Landfills are, typically,
designed according to the _________ strategy
Cap and Seal
primarily include chlorinated
and brominated compounds, for example, chlorofluorocarbons.
ozone depleting chemicals
can be formed from many chemicals including carbon monoxide, particulates, and
hydrocarbons
smog
bloom of vegetation in aquatic or terrestrial environments
Eutrophication
Reduction in the pH of the aquatic environment.
acidification
formed during the production of energy for manufacturing
facilities
Toxic chemical
These materials are renewable,
biodegradable, and have a lower environmental
impact than plastic.
natural materials
infinitely
recyclable and has a low environmental impact
glass
another durable and versatile material that
can replace plastic in some applications
metals
renewable, biodegradable,
and have a low environmental impact. They can be
used in a wide range of applications, including food
and beverage packaging. T
paper and cardboard
can be used to compare the environmental impacts of
producing plastic products.
Life cycle assessments (LCA)
methodology to assess the environmental impacts of a product, process, or service.
Life cycle assessments (LCA)
LCA is performed with a four-step
process that includes:
Definition of goal and scope
Life Cycle Inventory
Life Cycle Impact Assessment
Interpretation of the LCA result
ensures that comparisons can be made between different
materials, processes, or services
functional unit
one where the materials and energy required to produce
a product from raw materials to final product are used in the LCA calculations.
cradle-to-gate LCA
An LCA that considers manufacturing,
product use, and end-of-life is referred
to as
Cradle-to-grave
An LCA that
includes chemical recycling or reuse
can be referred to as
cradle-to-cradle
Inventory of relevant energy, material, and transportation inputs and related
liquid, gas, and solid generated outputs.
