Problem Statement
Intel Costa Rica is currently recycling 72 percent of waste.
The company wants to improve the recycling rate by focusing on cafeteria and construction waste.

In the Cafeteria
Trashcans located in inconvenient places
Waste is not being segregated
![Page 9: Intel Cafeteria and Construction Waste Management](https://reader036.vdocument.in/reader036/viewer/2022062722/56813a4b550346895da2424b/html5/thumbnails/9.jpg)

Recommendation for Cafeteria
Use segregated trashcans
Put in convenient locations
![Page 10: Intel Cafeteria and Construction Waste Management](https://reader036.vdocument.in/reader036/viewer/2022062722/56813a4b550346895da2424b/html5/thumbnails/10.jpg)

waste) and leftover waste from meals (10% of total cafeteria waste)
– Save 92 tons/year from being sent to the landfill
Savings of $1,107 (per year) on disposal weight alone

Co-Mingled vs. Source Segregated Recycling
Co-Mingled– 15-93 percent recycling rate– Labor intensive– Space efficient
Source Segregated– 90+ percent recycling rate– Cost efficient

Prior to Construction
Design to prevent waste – Example: design using standard size building
materials Establish the project specific waste
management plan– Identify waste– Identify disposal facilities
Assign role for someone to be responsible to implement waste management plan
![Page 28: Intel Cafeteria and Construction Waste Management](https://reader036.vdocument.in/reader036/viewer/2022062722/56813a4b550346895da2424b/html5/thumbnails/28.jpg)
28
Material Purchasing
Use tight estimatingAccurate Quantities + Over Order= Building+ Waste
Choose materials with minimal to no packaging
Ask for supplier coordination– Buy back– Take back– Returnable Pallets– Delivery Schedule
![Page 29: Intel Cafeteria and Construction Waste Management](https://reader036.vdocument.in/reader036/viewer/2022062722/56813a4b550346895da2424b/html5/thumbnails/29.jpg)
29
Site Arrangements
Identify sources of waste Place dumpsters
strategically – Size– Type– Location
Color code containers depending on the material disposed in them
Place segregated containers behind mixed containers
Empty containers regularly

Material Efficiency Indicator
Establish waste checks Analyze data Compare to other projects
– Average new construction yields 3.9 lbs of waste per square foot (Consigli Construction)
Use as a guideline for future projects

Servicios Ecológicos
Company that manages recycled materials for Intel
Created a program to employ single mothers and their families
Sends some materials to the United States and Central America to be recycled

Researching a Regional Recycling Market
Contacted CNP+L for a regional recycling market– There are minimal recycling markets in Central America
Mercado de Residuos y Subproductos Industriales (MERSI)
– Provides information to companies on handling industrial residues and subproducts
– Provides information on recycling and reducing– Aids companies in selling materials to other companies
![Page 35: Intel Cafeteria and Construction Waste Management](https://reader036.vdocument.in/reader036/viewer/2022062722/56813a4b550346895da2424b/html5/thumbnails/35.jpg)
35
Researching a Recycling Market in the United States
Researched recycling companies in the United States to provide a market for Costa Rica– RecyclingMarket.Net
Compiled a spreadsheet with companies, what they are able to recycle, and their contact information
![Page 36: Intel Cafeteria and Construction Waste Management](https://reader036.vdocument.in/reader036/viewer/2022062722/56813a4b550346895da2424b/html5/thumbnails/36.jpg)
36
Benefits of an Expanded Recycling Market
More materials can be recycled
There will be contact with the United States to learn about new technology
Servicios Ecológicos can expand their company and provide more jobs for the community
