Direct Reuse/Recovery On - Site
• It is preferred over off - site recycling/recovery as transportation of waste materials off - site is not required • The disadvantages are: o Capital cost for recycling equipment o The need for operator training o Additional operating costs that might incur • Three factors to consider: o The chemical composition of the waste and its effect on the process it is to be reused in o Whether the economic value of the reused waste justifies any modification to a process in order to accommodate it o The extent of availability and consistency of the waste to be reused

• Sample strategies include: o Keep the number of solvents to a minimum to make recycling easier and reduce hazardous waste management costs o Conduct all liquid cleaning at a centralized station to ensure solvents and residues stay in one area o Store drip pans for solvents in a solvent sink or tank for reuse o Use nonhazardous cleaners when possible o Use as little water as possible to clean spills, leaks, and drips o Reuse water if possible and prevent any process water from leaking into non - contact cooling water or stormwater
Life Cycle Assessment (LCA)
• Studies resource consumption, emissions, and their impacts • LCA traces: o The resources consumed o The emissions excreted during each phase • The output is a sort of biography: o Where the materials have been o What they have done o The consequences of this for their surroundings • Internalized vs. externalized environmental cost
Sale for Reuse Off - Site
• Supply and demand is the key • Requires a method to identify facilities capable of utilizing the waste and marketing the waste to them ( waste exchanges) • Potential liability concerns!
Sustainability Definitions
• Sustainable Development • Sustainability Engineering vs. Environmental Engineering
What Has Been Done?
• The Safe Drinking Water Act of 1974, amended in 1986 & 1996 • The Clean Water Act of 1977 and its amendments • The Clean Air Act, passed in 1970 • The Resource Conservation and Recovery Act (RCRA) went into effect in 1976 and was amended in 1984 • As an extension of RCRA, Superfund was enacted in 1980 • Revisions to Superfund in 1986 established Community Right - to - Know legislation
Transportation Waste
• The transportation industry generates: o Solid and hazardous wastes (replaces filters and batteries) o Industrial wastewater (washing) o Air pollution (VOCs, NOx, SOx ) o Noise pollution (aircraft operation) • The wastes are created during: o Maintenance and repair operations o Fueling operations o Transportation system operations
Industrial Ecology
• To identify and implement strategies that reduce negative environmental impacts, creating sustainable industries • To attain integrated, sustainable, closed - loop functionality of industrial systems • The waste of one process or system will become the raw material input for another
Energy and Atmosphere
• Use FAR environmental and energy guidelines for product and service purchases • ENERGY STAR Portfolio Manager • Adjust HVAC and ventilation to actual occupancy times of the building or use occupancy - based controls • Cooling systems with environmentally friendly refrigerants • Install CO 2 sensors to monitor ventilation rates • Respond rapidly to equipment malfunctions • Ask for occupant cooperation in turning off lights once leaving • Occupancy sensors in mechanical rooms, restrooms, etc. • Schedule large copier jobs during off - peak electric usage • Replace lighting fixtures with higher - efficiency alternatives
Water Efficiency
• Use FAR environmental and energy guidelines for product and service purchases • Use high - efficiency plumbing fixtures in lavatories, such as aerators on faucets, high - efficiency showerheads, and dual - flush toilets or high - efficiency toilets, and provide training for occupants for proper use • No automatic flush on toilets • Consider waterless urinals to save water while ensuring proper cleaning and maintenance • Water fountains with different acceptable temperatures • Incorporate taps into the design of fountains • Submetering of water systems
Materials and Resources
• Use Federal Acquisition Regulation (FAR) environmental and energy guidelines for product and service purchases • Look for low - VOC adhesives, wood flooring and furniture • Use water - based or low - VOC paints • Carpet, flooring, wall, and ceiling material with recycled content • Use cleaning chemicals that are Green Seal certified • Select energy efficient double or triple glazing windows • Centralize and separately ventilate printers and copiers to reduce air quality problems • Provide laptop computers in place of desktop computers to reduce energy and support mobile work • Use products that have manufacturer take - back programs
Waste Reduction and Management
• Use electronic communications versus printed material • Signage to educate building occupants regarding sustainability • Buy office products (e.g. paper) with high recycled content • Set machines to default to double - sided printing and copying • Institute a program to recycle materials • Reusable beverage containers, dishes, & utensils to cut waste • Hold trash and recycling workshops to educate occupants • Integrate waste reduction and management with municipalities • Require contractors to implement green cleaning practices • Use less - or non - toxic chemicals to manage pests • Divert construction waste from landfills
Energy Recovery
• Waste can be used as fuel supplement or fuel substitute
Goals and Scope
• Why do the study? o To guide the design of more environmentally friendly products o To demonstrate that you are an environmentally responsible manufacturer o To allow the public to form their own judgment about your products o To demonstrate that your products are greener than those of your competitor o To be able to claim conformity to ISO 14000 o Because the enterprise to which you are a supplier or subcontractor requires that you do so, so that they can claim conformity to standards
