WASTE REDUCTION

RE-THINKING PRODUCT LIFECYCLES

Landscape Development

Sustainable landscapes produce little impact on the surrounding environment.

When revising an existing landscape, salvage onsite materials and consider the following :

  • Balance the cut and fill on a site.
  • Reuse stone, boulders, brick or rock, broken concrete as pavers or dry stack walls.
  • Existing plants can often be relocated or incorporated into the new design.
  • Salvaged construction materials can be reused or donated to charity organizations.
  • Use re-manufactured or refurbished materials whenever possible.

California Integrated Waste Management Act

1989- The California Integrated Waste Management Act, or Assembly Bill 939, set waste diversion goals of 25 percent by 1995 and 50 percent by 2000 for each jurisdiction. 

2006- All California cities and counties were required to have achieved the 50 percent diversion rate by the beginning of 2006, or face the possibility of up to a $10,000 per day fine from the state.

2007- The City of San Diego approved a Recycling Ordinance Nov. 2007 requiring that plastic and glass bottles and jars, paper, newspaper, metal containers and cardboard at private residences, commercial buildings, and at special events requiring a City permit be recycled.

REDUCE, REUSE, RECYCLE

REDUCE - To buy less and use less

To reduce incorporates common sense ideas like turning off the lights, rain barrels, and taking shorter showers, but also plays a part in Composting/ Grasscycling (transportation energy is reduced), low-flow toilets, and programmable thermostats.

Includes the terms Re-think, Precycle, Carpool, Efficient, and Environmental Footprint/Foodprint.

REUSE - Elements of the discarded item are used again

Initiatives include Hand-Me-Downs, Garage Sales, Quilting, and Composting (nutrients). Includes the terms Repair, Regift, and Upcycle.

RECYCLE - Discards are separated into materials that may be incorporated into new products.

This is different from Reuse in that energy is used to change the physical properties of the material. Initiatives include Composting, Beverage Container Deposits and buying products with a high content of post-consumer material.

Home improvement outlets sell donated, new, used, and surplus goods to the public at greatly reduced prices.

Recycle is preservation-oriented, emphasizing sustainable practices through reuse.

CONSTRUCTION AND DEMOLITION WASTE

2008- The Construction and Demolition (C&D) Debris Deposit Ordinance (PDF) took effect.

The ordinance requires that the majority of construction, demolition and remodeling projects requiring building, combination and demolition permits pay a refundable C&D Debris Recycling Deposit and divert at least 50% of their debris by recycling, reusing or donating usable materials.

The ordinance is designed to keep C&D materials out of local landfills and ensure they get recycled."

GREEN WASTE- COMPOSTING

Composted organic material is plant matter that has been decomposed and recycled as a fertilizer and soil amendment. Many communities have recycling bins that are collected and added to community composting efforts.

Some sources of compost-able materials include:

  • Composting organic materials from the lawn, pruning trees & shrubs and vegetable kitchen waste recycles waste to decomposed organic material or compost or mulch.
  • A compost bin or worm compost system removes green waste from the landfill.

COMPOSTING PROGRAMS

Training, Workshops, and Composting Bins

At the Miramar Greenery, the City of San Diego composts yard trimmings and food scraps for 70 days, screens the resulting compost to one-half inch size, processes mulch and wood chips.

These water saving, recycled materials are available at a nominal price from the Miramar Greenery.
