The County integrates environmental considerations into purchasing decisions alongside price, performance, and availability. The goal is to reduce pollution, conserve resources, and promote sustainable markets.
Environmentally preferable products may include items that are:
Recycled, recyclable, or reusable
Energy or water efficient
Biodegradable, compostable, or non-toxic
Durable, resource-efficient, or made from renewable materials
Policy highlights:
Preference of up to 5% price advantage for environmentally preferable products.
Consideration of life-cycle costs (maintenance, operation, disposal) as part of “best value” purchasing.
Specifications and solicitations will include green purchasing requirements whenever possible.
Departments must ensure staff and suppliers are aware of these policies.
Ability of some substances to collect in plant and animal tissue. These substances increase in concentration as they pass through the food chain when the plants and animals are consumed by larger animals (such as humans).
Products produced from renewable plant and animal sources. They are generally presumed to be more environmentally benign than their petroleum based counterparts, although this is not necessarily true. They are usually biodegradable and can be returned to the earth at the end of their useful life or recycled and used again. As defined by the US Farm Security and Rural Investment Act (FSRIA), a biobased product is a product determined by the US Secretary of Agriculture to be a commercial or industrial product (other than food or feed), that is composed in whole or in significant part, of biological products or renewable domestic agricultural materials (including plant, animal and marine materials) or forestry materials.
The ability of a substance to decompose in the natural environments into harmless raw materials. To be truly biodegradable, a substance or material should break down into carbon dioxide (a nutrient for plants), water, and naturally occurring minerals that also do not cause harm to the ecosystem. In terms of environmental benefits, a product should take months or years, and not centuries, to biodegrade.
Any of a group of compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen and have been used as refrigerants, cleaning solvents, aerosol propellants and in the manufacture of plastic foams. The uses of CFCs are being phased out because they destroy the plant's stratospheric ozone protection layer.
A product that can be placed into a composition of decaying biodegradable materials and eventually turn into a nutrient-rich material. It is synonymous with "biodegradable," except it is limited to solid materials (liquid products are not considered compostable).
System for allowing organizations to combine their purchasing power in order to negotiate better prices and reduce the purchasing costs of a formal bid process.
A product that is in the upper 25 percent of energy efficiency for all similar products, or that is at least 10 percent more efficient than the minimum level meeting US federal government standards.
Products and services that have a lesser or reduced effect on human health and the environment when compared with competing products and services that serve the same purpose. This comparison may consider raw materials acquisition, production, manufacturing, packaging, distribution, reuse, operation, maintenance and/or disposal of the product or service.
A product and waste management system in which manufacturers and consumers take responsibility for the environmentally safe management of products once the products reaches the end of their useful life. As the manufacturers have the greatest ability to influence product design, they have the greatest responsibility for the product's end of life reuse, refurbish, recycling, or legal disposal. Retailer "take back" or "mail back" programs are two such examples.
Accounting for the economic, environmental, land use, human health, social and heritage costs and benefits of a particular decision or action to ensure no costs associated with the decision or action, including externalized costs, are left unaccounted. (Compare with Lifecycle Cost and Product Life cycle.)
Any of several dozen heat-trapping trace gases in the earth's atmosphere that absorb infrared radiation. The two major greenhouse gases are water vapor and carbon dioxide; lesser greenhouse gases include methane, ozone (O3), CFCs, and nitrogen oxides.
A self-assessment system developed by the U.S. Green Building Council for rating the environmental preferability of new and existing commercial, institution, and high-rise residential buildings.
The amortized annual cost of a product or service, including capital costs, installation costs, operating costs, maintenance costs, and end of useful life costs discounted over the lifetime of the product or service. (Compare with Product Life cycle.)
Written or printed material about a product that includes information on though product's physical and chemical characteristics; physical and health hazards; precautions for safe handling and use; control measures; emergency and first aid procedures; the date of preparation of the MSDS or the last change to it; and the name, address, and telephone number of the manufacturer.
Toxic chemicals that persist in the environment and increase in concentration through food chains as larger animals consume PBT-laden smaller animals. They transfer rather easily among air, water, and land, and span boundaries of programs, geography, and generations. As a result, PBTs pose risks to human health and ecosystems. They are associated with a range of adverse human health effects, including effects on the nervous system, reproductive and developmental problems, cancer, and genetic impact. They include heavy metals and chemicals such s mercury, dioxins, and PCB's (polychlorinated biphenyls).
Percentage of a product made from materials and byproducts recovered or diverted from the solid waste stream after having completed their usefulness as consumer items and used in place of raw or virgin material. Post-consumer recycled content includes materials (such as paper, bottles, and cans) collected for recycling.
Recovered materials that were production finished materials, products or byproducts that did not reach the consumer for whose use they were intended, and have been diverted from the solid waste stream for the purposes of collection, recycling, and disposition.
A percentage by which offered prices for recycled products are reduced for purposes of bid evaluation. For example, under a 5 percent price preference, if a bid of $1.00 per unit is received for an environmentally preferable product meeting specifications, the bid price will be reduced by $0.05 (5 percent) and evaluated as though it had been for $0.95. If this bid results in a contract award the price actually contracted will be the bid price of $1.00 per unit.
The culmination of environmental impacts for a product, including raw material acquisition, manufacturing, distribution, use, maintenance, and end of useful life or ultimate disposal of the product. (Compare with Life cycle cost.)
Material and byproducts that have been recovered or diverted from solid waste and have been utilized in place of raw or virgin material in manufacturing a product. It is derived form post-consumer recycled materials, manufacturing waste, industrial scrap, agricultural waste, and other waste material, but does not include material or byproducts generated from, and commonly reused within, an original manufacturing process.
Materials made from plant-based feedstock capable of regenerating in less than 200 years, such as trees and agricultural products. Rapidly renewable resources, such as grain-based feedstocks, regenerate in less than two years.
Chemicals that readily evaporate and contribute to the formation of air pollution when released into the atmosphere. May VOCs are classified as toxic and carcinogenic.
A product that is in the upper 25 percent of water efficiency for all similar products, or that is at least 10 percent more efficient than the minimum level meeting US federal government standards.
