RCRA-C vs. RCRA-D
Both RCRA-C and RCRA-D regulate only solid wastes (SW).
What is a solid waste? (flowchart)
RCRA-C regulates only HAZARDOUS solid wastes while RCRA-D regulates only non-hazardous solid wastes.
Municipal (non-hazardous) solid waste is effectively any solid waste that is not a hazardous solid waste so, it is important to know a little bit about hazardous waste.

Hazardous wastes are
- Materials specifically LISTED by EPA
- F-List, K-List, P-List, and U-List
- Material that meet HW physical properties CHARACTERISTICs
- Toxicity, Reactivity, Ignitability, and Corrosivity
- Materials DECLARED hazardous by the generator
What types of materials are RCRA-D wastes (non-hazardous solid wastes)?
What is Municipal Solid Waste (MSW)?
What are the sources of RCRA subtitle-D Wastes?
- Hazardous - regulated under 40 CFR 261 Subtitle C
- Regulatory Defn: SW which because of its quantity, concentration, physical, chemical, or infectious character, may cause or significantly contribute to an increase in mortality or an increase in serious, irreversible or incapacitating reversible illness or may pose a substantial present or potential hazard to human health or the environment when improperly transported, disposed of, stored, treated, or otherwise managed.
- Disposable equipment, instruments, utensils, or fomites from rooms of patients who have been diagnosed or are suspected of having a communicable disease, laboratory wastes laboratory wastes such as tissues , blood specimens, excreta, and secretions from patients or lab animals, disposable fomites, and surgical op room pathological specimens, fomites and other materials from outpatient areas and emergency rooms
- Federal mandates required the States to develop and enforce acceptable regulations
What is waste composition like in other Countries?
What is waste composition like in the U.S.?
Source Data: US EPA Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2006
Composition of Waste Generated (before recycling) in the U.S. in 2006
2006 U.S. Total Waste Generation – 251.3 million tons
Composition of Waste Disposed (after recycling) in the U.S. in 2006
2006 U.S. Total Waste Disposal – 169.5 million tons
Composition of Recyling Stream in the U.S. in 2006
2006 U.S. Total Waste Recycled– 81.8 million tons
Think: Based on the data in the three pie-chart figures above, what was the overall recycling rate in the U.S. in 2006?
Think: The three pie chart figures above were created using the data presented below. How was this done?

Negligible = Less than 5,000 tons or 0.05 percent.

What is waste composition like in Georgia?
Composition of Waste Disposed in Georgia in 2004
2004 Georgia Total Waste Disposal – 15.8 million tons
Think: How could the data in the USEPA Table on U.S. Waste Composition be used with the Georgia Disposed Waste Compostion Pie-Chart to predict the composition of the waste generated in Georgia? What assumptions would be necessary?
WORK THIS PROBLEM
(Here is a solution to this problem)
Rework the above problem using the following information: 80% of the homes have food grinders in which they grind 40% of their food waste. The overall recycling efficiency is 20% (not 11%). The composition of the disposed and recycled waste streams remains the same. Here is the answer.
