Composting at work: It's different than at home

Business compost goes to a different processing facility and has different guidelines than your home green bin compost.

business compost goes to a biodigester and creates energy

Did you know that your compost bins at home and work have different guidelines? They go to different processing facilities and have different rules about what's allowed.

Business compost makes energy. The food scraps collected at Portland businesses (restaurants, offices and more) go to a facility that turns them into energy.

How it works

Food waste is blended into a liquid and is broken down by bacteria. The bacteria create methane, which is captured and burned to make electricity. The leftover materials are used as fertilizer to enrich soils.

It's food only

Food is the only thing allowed in business compost, with the exceptions of BPI-certified compostable bags, used paper coffee filters and tea bags. Non-food materials gum up the system and have to be filtered out. See examples of what's allowed and print posters for your workplace.

Things you should NOT compost at work

Items not allowed in compost

While the following items are allowed in your green bin at home, they should not go in compost bins at Portland businesses:

  1. pizza boxes
  2. napkins, paper towels
  3. yard debris, flowers*

Also, to-go containers, cups and utensils are never allowed in compost, at home or at work. This applies to all types of containers, even those labeled "compostable" or "biodegradable." They should always go in the trash. 

*Wondering why flowers aren't allowed? The stems are tough and woody, which makes them difficult for the microbes to break down.

Upgrade your lighting and support affordable housing

Support Central City Concern while upgrading to energy-efficient LEDs.

LAMP program

Looking to upgrade your lighting to energy-efficient LEDs? Consider going through the LAMP program, organized by Lloyd Eco District and open to all businesses in Portland.

Benefits of LAMP

Energy savings: LED lamps and fixtures lower energy use and last a long time, reducing costs and hassle of replacement.

Community benefits: A portion of proceeds help build affordable housing, through Central City Concern.

Cost savings: LED lamps and fixtures come at a bulk purchase price, and it typically pays back your investment in around 2 years.

Service: The vetted provider, Conserve Energy, LLC, will manage product selection and installation and handle the rebate paperwork. Conserve Energy is an Energy Trust of Oregon Performance+ Trade Ally.

Who can get LEDs through LAMP?

Any business, including tenants and property managers. You can get LEDs for an existing workspace, a tenant renovation or a whole building retrofit.

How it works

First, find out if you could benefit from LEDs:

  1. Contact Courtney at Lloyd Eco District to get started: or call her at 310-804-2817.
  2. Courtney will connect you with their contractor, Conserve Energy, LLC.
  3. Conserve Energy will work with you, over the phone or in person, to understand what type of lighting you currently have and provide LED product recommendations and pricing.

Then, if you choose to go forward with a project:

  • Conserve Energy will supply the LED lamps and fixtures, install them (if you desire), and handle all of the Energy Trust of Oregon rebate paperwork.
  • After the project is complete, a donation is sent to Central City Concern, a local social service and affordable housing provider.

Tips to save energy at your office

Whether you lease or own your space, there are lots of things you can do at your office to reduce energy use.

There are many no- and low-cost steps you can take to reduce your energy consumption and control costs. And some upgrades are eligible for cash incentives from Energy Trust of Oregon.

Lighting, computers and heating and cooling

Turn off lights when not in use or when natural daylight is sufficient. This can reduce lighting expenses by 10 to 40 percent!

Upgrade your lighting with new energy-efficient bulbs and fixtures, and use controls to save energy and improve lighting quality. Cash incentives may be available from Energy Trust. Or purchase reduced-cost bulbs through the LAMP program, which gives a portion of proceeds to Central City Concern (this program is run by Lloyd Eco District, but is open to all organizations in Portland).

Office equipment

Set computers, computer monitors, printers, copiers and other office equipment to sleep when not in use.

Consolidate stand-alone office equipment to be shared by multiple users. Typical cost savings can reach 30 to 40 percent for electricity, hardware, supplies, and maintenance!

Heating and cooling

Set back thermostats for evening and weekend hours, and adjust temperatures seasonally. Or even better, install programmable thermostats to automatically reduce heating and air conditioning during closed hours. Cash incentives may be available.

Close your shades and blinds in the summer to keep your office cool – during the day, and before everyone goes home in the evening and on weekends.

3 tips to bring bike riders to your business

Set up (free!) bike racks and promote your bike friendly offerings.

attract cyclists to your business

The sun’s out and so are the cyclists! Here are some ways you can bring more bike riders to your business.

Bike racks

Did you know the City of Portland will install bike racks in front of your business for free?

The bright blue bike racks attract riders’ attention. Even if their destination is further down the street, if you’ve got the parking spot, they’ll spend a few moments in front of your business both when they arrive and when they leave. Request a rack.

Or get creative and have a custom art rack created that accentuates your business. We’ve seen all kinds of fun racks around town: giant eyeglasses, a pink doughnut, a Fremont Bridge replica, and an enormous baking whisk.

Be a Bike Friendly Business

If you run a retail store, restaurant, coffee shop or bar, show that you welcome bicyclists through Travel Portland’s Bike Friendly Business program.

The program is free, and the signs to post in front of your business start at only $26. Check it out.

Offer perks and discounts

From dentists to physical therapists, we’ve see Portland businesses offer discounts for customers who arrive by bike. Even a small perk can get a customer’s attention and build loyalty to your business.
