The Expert answers:
That would be a question for your local Solid Waste Division for the City you reside in. Hospitals are responsible for proper disposal of bio-hazardous waste. Now, with respect to individuals that live in your community that have for example Diabetes:
Some cities use landfills, some have energy-from-waste facilities that burn all Municipal Solid Waste (generating electricity in the process).
The individuals throw their sharps in the trash that is picked up by whichever trash company, the local Solid Waste Division for your city / state tells them where they are permitted to take it.
Hope this helps.
Susan asks…
Is oxaloacetate and citric acid the same thing?
In my bio book it says that during the Krebs cycle, the beginning product (citric acid) is recycled back into itself, and it says that the end product is oxaloacetate which indicates that recycling has occurred. I’m a bit confused….are these two chemicals the same thing?
The Expert answers:
At the end of the Krebs cycle, the final product is oxaloacetic acid. This is identical to the oxaloacetic acid that begins the cycle. Now the molecule is ready to accept another acetyl-CoA molecule to begin another turn of the cycle.
Acetyl-CoA enters the Krebs cycle by combining with a four-carbon acid called oxaloacetic acid. The combination forms the six-carbon acid called citric acid.
So Oxaloactetate and citric acid are not the same.

Why Does my Maytag Centennial Washer Refuse to Start When Locked?
Our Household has had a Maytag Centennial Washer for eight months and it won’t start after it locks. I wash off the top of the washer whenever Ioad it because I dumpster dive/recycle to remove the odor from the washer’s opening. Was that confusing the washer’s cycles?
The Expert answers:
I don’t know about the washer, but your question sure confused me.
Check the safety latch that keeps the washer from working when the lid is open.

Carol asks…
Describe the differences in the way that energy compared to materials move through ecosystems.?
I understand that there are trophic levels & that energy is decreased at each one and that it involves a food chain. I also understand that matter is constant and atoms are recycled for materials. I just don’t know what other differences exist between the cycling of energy and the cycling of materials.
The Expert answers:
Tropic levels general describe the transfer of energy as each level only having 10% of the energy available for use from the previous trophic level.
Michael asks…
32) Quantities of mineral nutrients in soils of tropical rain forests are relatively low because?
A) the standing crop is small.
B) microorganisms that recycle chemicals are not very abundant in tropical soils.
C) the decomposition of organic refuse and reassimilation of chemicals by plants occur rapidly.
D) nutrient cycles occur at a relatively slow rate in tropical soils.
E) the high temperatures destroy the nutrients.
The Expert answers:
I’d say C is the right answer: decomposition and reassimilation are rapid.
I initially had the wrong answer with my own reasoning, but I found the web site shown below as my source, and I learned what nutrient cycle means. From that site, “As organic material decays, it is recycled so quickly that few nutrients ever reach the soil, leaving it nearly sterile.”
Briefly, rainforest soils are depleted of nutrients, so the plants depend primarily on the rapid decomposition of organic material. The fast growing vegetation immediately takes up the freshly released nutrients.
The web site is worth reading in depth for a full understanding.
Donna asks…
Where can I find information about Styrofoam and Paper cups environmental impact in it’s Life Cycle?
I am doing a Life Cycle analysis of the two types of disposable cups to compare and derive which one is more harmful to the environment in its whole life cycle. Starting from the Resource Extraction, followed by Manufacturing (Raw Material & Product), Usage and Recycling/Disposal. Any detailed sources providing these information are welcome. Thanks!!
The Expert answers:
If you are an American then be aware that disposable cups are not made of styrofoam, they are made of expanded polystyrene. Styrofoam is a brand name that Americans misuse, like people say they will Hoover when they mean they will vacuum clean. Styrofoam is EXTRUDED polystyrene foam, a different product used to insulate walls. Disposable coffee cups are not made out of Styrofoam, they are made out of EXPANDED polystyrene.
When you are clear which product you actually mean, then the following link might be helpful to you:
