Waste Not, Want Not

Being an environmental science teacher, I of course wondered about what happened to all the garbage produced on board the JOIDES Resolution. Garbage from ships can be just as deadly to marine life as oil or chemicals, so we need to ensure all trash is properly disposed of. To quell my curiosity, I was taken on a short trip to the stern of the ship, aft of the drill floor, to see where the trash goes. I do wonder if I’m the first person to ask to be taken to the incinerator…

The process of disposing of our wastes begins with everyone (hopefully!) taking the time to place their refuse into the proper cans. In the science lab areas, there are separate receptacles for burnable waste (like paper), plastics & recyclables (like aluminum cans), and even latex gloves. In the event that we toss something into the wrong bin, it will be sorted before the next step in the process.

Waste bins.

Food waste is a special circumstance- according to the International Maritime Organization, it is permissible to dispose of food waste into the ocean, so we have a designated receptacle in the mess hall. (http://www.imo.org/en/OurWork/environment/pollutionprevention/garbage/pages/default.aspx)

Once all the trash is collected from the small bins around the ship, it’s brought to the stern for processing. We have one (massive!) incinerator for all the burnables, and another incinerator for the waste oil produced from our machinery. The paper incinerator runs pretty much constantly- each cycle takes 3 hours total (1 hour for heating to 1200+ degrees & combustion, and 2 hours for cooling). The ash that’s produced from the burning of the paper products is collected into bags for disposal once we get back to shore.

We also have special repositories for used batteries and electronic waste. We do all we can to keep the environment clean!


If you’re an educator, one easy way to get students thinking about the trash that they produce is to challenge them to carry around a bag of their trash for a certain number of days. ALL trash is collected, save for hygiene products and food, since those are very unsanitary. At the end of the allotted time frame, students can sort the trash into paper, plastic, aluminum, etc. and weigh it or tally the number of items. This activity really does make them aware of how much garbage they produce on a daily basis (expand this with calculations for trash produced per week/month/year!) and can lead into valuable discussion about the 5 Rs (Refuse, Reduce, Reuse, Repurpose, Recycle) and renewable vs. non-renewable resources.


As I was writing this, I remembered that when I was a little kid, I was obsessed with the garbage men when they’d come by weekly to pick up our trash set at the end of our driveway. Early in the morning, I’d hear the squeaky brakes of the truck and run across the hall to stand on the radiator in order to see out the window and just watch the garbage men. Now, many many years later, I’m curious about the waste flow on a ship in the Pacific Ocean. Maybe I’m in the wrong career field, and should have gone into waste management!


THANK YOU to SIEM’s Ian Barnes for setting up the incinerator tour, and Allen Torres for showing & explaining things to us!






Hello there! My name is Tammy Orilio and I am sailing on board the JOIDES Resolution, Expedition 376: Brothers Arc Flux as an Education & Outreach Officer. I look forward to sharing both science and shipboard life with you! In my other life, I teach Marine Science and Advanced Placement Environmental Science at Marjory Stoneman Douglas High School in Parkland, FL. I love being able to share these experiences with my school community!
