The Impact of Refrigeration
On Environment • Electricity is used- has to be
made• Produces waste- used
lamps, broken parts, ect.• Refrigerator coolant • With food lasting longer,
less waste is produced
On Humans• Food can last longer• Less contamination• Cold products when
needed• Transportation of products
is easer
