The term "solid waste" is defined at 40 Code of Federal Regulations (CFR) Section 261.2(a)(1) as any discarded material that is not excluded under 40 CFR Section 261.4(a) or that is not excluded by a variance granted under 40 CFR Sections 260.30 and 260.31.
Spent or Unused Catalyst Even if you can’t produce enough to run a machine exclusively on biodiesel, what you have can be mixed with petro-diesel or home heating oil in any proportion and still deliver excellent results. If the facility generates less than 100 kg (220 lbs) of total combined hazardous waste per month and stores no more than 1,000 kg (2,200 lbs) of total combined hazardous waste at any one time, it qualifies for the CESQG exemptions. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Ignitable hazardous wastes are identified with the code D001. stream If you have anything at all that runs on diesel, you should consider at least experimenting with biodiesel home brewing, perhaps in collaboration with neighbors, friends, or family so that you can share the costs and the work involved. Like waste methanol, waste catalyst is not subject to RCRA if it is returned to the process in a closed-loop system, but it would be a hazardous waste outside a closed-loop system until it was returned to the process.
Businesses or not-for-profit entities that operate very small plants are likely subject to the much less stringent "conditionally exempt small quantity generator" (CESQG) hazardous waste regulations. Most people who home brew this stuff use recycled vegetable oil because using new oil made from a crop such as canola, sunflowers, mustard, or peanuts would drive up the cost significantly (the idea of making biodiesel at home with original crops would represent the height of self-sufficiency, but there is a good reason why you don’t find a lot of inspiring testimony out there from people who have actually tried to do this). The Occupational Safety and Health Administration (OSHA) requires that material safety data sheets (MSDS) be provided by chemical suppliers.
No matter what safety precautions are put in place or what equipment you use, making biodiesel will never be a safe hobby and can place you, your property, and your family at risk of injury or even death.
Listed wastes are wastes from: generic industrial processes (F-listed), certain sectors of industry (K-listed), unused pure chemical products and formulations (U-listed), and acutely toxic unused pure chemical products and formulations (P-listed). Typically, waste glycerin is not a hazardous waste.
The costs for producing biodiesel at home – with used vegetable oil acquired for free – usually ranges somewhere between 50 cents and $1 per gallon with all inputs factored in. Methanol, the catalysts, and the acids are toxic chemicals. Used oil may be a hazardous waste, but the used oil regulations assume the material will be handled separately from the hazardous waste and thus recycled. Some of the solid waste could be "hazardous waste," subject to Subtitle C of RCRA. It recommends that a chemical hygiene plan be instituted in every lab, including adequate ventilation and clearly stated guidelines for minimum exposure to hazardous chemicals. Sodium hydroxide and potassium hydroxide are strong bases which can burn unprotected skin and kill nerve cells before pain can be felt. will need to be purchased and used if you are going to handle them safely. Homemade biodiesel can potentially fill a respectable percentage of a household’s fuel needs, and if you are currently running diesel engines or are considering the possibility of doing so in the near future, you can definitely save money and enhance your self-sufficiency if you are willing to take a how-to course on this fascinating subject. Any spent catalyst (or other waste material) with a pH greater than or equal to 12.5, or less than or equal to 2, is a hazardous waste.
EPA developed the toxicity characteristic (TC) to identify wastes likely to leach dangerous concentrations of toxic chemicals into ground water. Biodiesel is an excellent lubricant that will help to extend engine life. The facility should then determine if the accumulated materials from the aerosol cans are hazardous. A solid waste can include solid materials, liquids, and contained gases. Anyone interested in making biodiesel at home should harbor no illusions. Methanol vapors are heavy, and can travel along the ground to a source of ignition.
