1995 Generated Recycled– Food waste 14.1 M tons 3.4%– Yard waste 30.6 M tons 22.9%
2006 – Food waste 31.3 M tons 2.2%– Yard waste 32.4 M tons 62.0%
We’ve made huge strides, BUT there are still millions of tons still being landfilled.
Need to establish extensive yard waste composting operations to help support the development of food waste composting operations.

Building Sustainability Building Sustainability From the Ground UpFrom the Ground Up
4
GreenScapes is:• Multi-media EPA Partnership
Program designed to promote a wide variety of environmentally beneficial landscaping and land management practices.
5
GreenScapes is:• Designed to help preserve natural
resources and prevent waste and pollution by encouraging more holistic decisions regarding waste, water, chemicals, energy, and land use.
6
GreenScapes is:• Designed to provide cost-efficient
and environmentally friendlysolutions - improving both an organization’s bottom-line and the environment.
7
Think Big:• Roads & Highways• Commercial Buildings• Industrial Sites• Military Installations• Brownfields• Colleges & Universities• Recreation areas - parks, golf courses, ski
resorts, amusement parks, …
8
Think about:• Millions of tons of waste materials that are
– Hauled away to a landfill,– Buried, or– BurnedEach and every day from landscaping construction
and maintenance operations:• Trees• Shrubs,• Brush• Lumber• Asphalt• Concrete, etc…
9
Also, consider the millions of gallons of:
• Water• Pesticides• Fertilizers• Fuels• Oil Used each & every day in building and
maintaining these lands.
10
Make more holistic and sustainable decisions regarding and the impact each of these has on the other:
– Waste generation & disposal– Use of
• Water• Chemicals• Air• Plants• Energy• Land & Wetlands
11
The GreenScapes Solution Focus on the 4 Rs
• Reduce• Reuse• Recycle• Rebuy
12
Reduce:
• The first and most important step towards efficient use of resources & pollution prevention.
13
Reduce:
• Waste generation by utilizing slow-growing, low maintenance plant materials.
• Water use - Incorporate compost into the soil to help improve water absorption and retention.
• Pesticide use - Implement an Integrated Pest Management (IPM) program.
• Energy - Strategically plant vegetation outside and around buildings to reduce indoor heating and cooling needs
14
• Avoid landscaping products that require frequent replacement or maintenance to reduce future waste.
• Durable products will long outlast those of lesser quality, reducing future waste generation and the need to purchase new or replacement products.
15
Consider:• Reduce or eliminate
plastic silt fencing... and worse
–Substitute with blankets, berms, and filter-socks made of compost.
16
Compost provides: • Superior filtration & erosion prevention/control
• More easily installed & maintained
• Control & reduction of non-point source pollution.
• Does not require removal or disposal from site once job is complete
17
A few additional ways to reduce:• Reduce nonpermeable hardscape to minimize
rainwater runoff & erosion.• Switch from benches, boardwalks & bridges
made from wood to long-lived plastic lumber.• Conserve water and reduce maintenance by
Xeriscaping.• Reduce chemical use by using native plants
and organic biobased fertilizers.
18
Reuse:• Key to effective management
by making the most of your valuable resources -–Financial–Materials
19
Reuse:• Waste - Chip woody waste and tree clippings
into mulch for use on-site.• Reuse soils within the work site; create
mounds or berms to serve as wind breaks or to add visual interest.
• Water - Use collected rainwater for irrigation and water features.
20
Ways to reuse:• Chip trees and wood
waste into mulch.– Saves money on
disposal costs and commercial mulch purchases
– Provides benefits of mulch:
• Moisture retention• Weed prevention• Erosion control
21
Additional reuse options:• Disassemble and use structural wood elsewhere,
sell or grind into mulch. Return wooden pallets to your supplier whenever possible.
• Donate healthy plants to community gardens, schools, churches, or other local local non-profit organizations when updating or removing trees & shrubs from landscape.
• Use alternative sources of irrigation water such as gray water, reclaimed water, and collected rain water.
22
Recycle:
• Save money on disposal costs, by recycling waste materials
– you may even be able to get a few dollars for them.
23
Recycle:
• Waste - Send green waste and food waste that cannot be composted on site to a local composting facility.
• Waste - Provide recycling receptacles next to trash receptacles.
• Water - Recycle gray water for irrigation and equipment wash downs.
24
Consider: • Recycle plastic fencing, barriers, plant & pesticide containers.
• Collect and recycle used oil & tires from your vehicles and equipment.
25
Rebuy:• Rebuying means re-thinking
your purchasing habits.
• Look for products that meet your needs but have a better environmental profile than your current product purchases.
26
Consider:• Recycled content• Biobased products (incl. fuels & lubricants)
• Renewable energy & products• Energy & water efficient
Rebuying is key to sustainability by putting valuable materials back to work .
Change your thinking:It’s not waste – it’s another resource.
27
Rebuy:
• Waste - Select long-lived durable products such as composite lumber.
• Water - Install a green vegetated roof to reduce or eliminate stormwater and "heat island" effect.
• Fertilizers - Purchase organic, biobased, or slow-release fertilizers
• Energy - Use high efficiency lighting for roadways, parking lots, security, and landscaping.
28
For example:
• Use compost to minimize / eliminate:– Soil erosion– Runoff– Nonpoint source
pollution– Irrigation– Fertilizers– Pesticides It’s both a recycled &
biobased product.
29
A Proven Technique
• Compost blankets, berms, and filter socks have been added to the US EPA menu of Best Management Practices (BMPs) for storm water management - NPDES.
• State DoT’s are specifying compost for roadside erosion control.(http://www.dot.state.tx.us/des/landscape/compost/topsoil.htm)
30
Did You Know?:• For every 1% of organic matter, the
soil can hold 16,000 gallons of plant-available water per acre of soil down to one foot deep!
• Most soils average approx. 1% organic content
• Healthy soils average 5-6%(5 x 16,000 = 80,000 gallons water holding capacity)
31
Better, Faster, Cheaper Cleanups
• Provides an inexpensive & straightforward solution to managing hazardous industrial waste streams & remediating soils contaminated with toxic organic and inorganic compounds.
32
Proven effective for:
• Chlorinated & nonchlorinated hydrocarbons• Wood-preserving chemicals• Solvents• Heavy metals• Pesticides• Petroleum products• Explosives
33
Returns site to precontamination condition
• Provides soil conditioning• Nutrients• Water retention• Erosion control• Micro-organisms essential for healthy soil
34
• Select plastic lumbermade from recycled bottles & bags.– Extremely durable– Lasts longer than wood– Requires less
maintenance than wood
• Labor• Paint / solvents• Repairs
– Significant long-term savings.
Rebuy
35
• Specify rubberized asphalt (made from recycled tires) for:– Walking paths– Bike paths– Cart paths– Parking lots
Extends the life of the trails and reduces frequency of repairs.
Rebuy
