Ch. 17 Sustainability Flashcards
Meeting the needs of the present without compromising the ability of future generations to meet their own needs.
Sustainability
U.S. Environmental Protection Agency
Department of Energy
set standards for energy efficient products (most energy-efficient = Energy Star)
Includes:
- Purchasing energy-efficient equipment
- Heating and cooling equipment should be well insulated
- Using equipment properly
- Maintaining equipment
- Idling or turning off equipment when not in use
Energy conservation/management for foodservice equipment
Use energy efficient light bulbs
- Replace incandescent with LEDs
Put in occupancy sensors
Install systems which adjust indoor lighting to ambient light coming in from the outside
Set up daylighting systems which harvest sunlight for indoor use
Energy conservation/management for lighting
In most jurisdictions consumers pay for water three times
When it is purchased
To heat or cool it
To dispose of and treat wastewater
Low flow valves in sinks
Sensor faucets
Low flow toilets
Hot water recirculating systems
Tankless water heaters
Ways to reduce water use
A machine that uses large amounts of water as it grinds solid waste and discharges it into the sewer system
- Creates a burden on both water distribution systems and wastewater treatment
- New installations are banned in some cities; taxed heavily in others
garbage disposal
A machine that grinds solid waste, then extracts the solids so that only the water is discharged into the sewer system
- Less impact on wastewater treatment, since solids are not put into the system
- Newer ones recirculate the water, so less water is sent to the treatment plant
pulper
A device that is used in dishwashing areas of foodservice that sprays water on dirty dishes to remove waste that is left on plates, before the dishes are washed
- Newer versions are as effective at pre-rinsing as older models, but use about half of the water
- Often available at little or no cost to encourage water conservation
Prerinse nozzle
With older dishwashers, always run them with full loads
Some newer models recirculate water
If buying a new dishwasher, Energy Star standards address both energy and water conservation
Energy-efficient booster heaters are ancillary to high temperature dishwashers
Warewashing
Changes in packaging
Recycling
Food recovery
Waste Management:
Strategies to divert waste materials from landfills
Use less packaging overall
By in bulk, not in PC containers
Choose reusable packaging
e.g. plastic milk crates
Specify packaging that is recyclable
e.g. cardboard
Specify compostable packaging
Made from organic materials such as rice
reducing use of raw materials through changes in packaging
Changes waste materials into new products
- Paper, cardboard, glass, metals and some plastics can be recycled
- Batteries, toner cartridges, and electronics are also recyclable
Waste Management: Recycling
- Source reduction
- Feed hungry people
- Feed animals
- Industrial Uses
- Composting
- Landfill/Incineration
Waste Management:
Food Recovery Hierarchy
- Conduct a waste audit to determine what and how much food is being wasted
- Identify methods to reduce the waste which may include:
Changing the menu
Reducing portion size
Better inventory management
Improved production forecasting
Repurposing excess food products
Source Reduction
