6 Tips for Disposing of Liquid Waste

Getting rid of waste, particularly liquid waste, is not at the top of your to-do list.  Understandably, the waste generated by many of the manufacturing and machining processes gets in the way, and can be annoying and costly of which to dispose. Here are some simple best practices that most all generators should follow.

  1.  Become Informed – Learn about the contents and characteristics of your waste stream.  Quite often, the person in charge of waste stream management has not been properly educated or trained about the waste.  It’s not uncommon for many health and safety responsibilities to fall upon a team member that is already deluged with other responsibilities at the facility.  However, not knowing the laws and responsibilities regarding your waste stream has consistently not been an acceptable answer when confronted with the relevant government agencies.  Safe to say, you could be breaking the law and not even know it.  Educate yourself!
  2. Separate Your Waste – When storing liquid waste, be sure to segregate each waste stream.  Quite often the cost of a waste stream is determined by the way the waste has to be treated at a recycling facility.   Safe to say, hazardous waste is usually more costly than non-hazardous waste streams.  If you co-mingle the streams, you risk the possibility of costing yourself more money and potentially creating a substance or material that is much more flammable and combustible.
  3. Take Precautions – When transferring waste, take extra precautions for make sure the transfer is done safely.  This is often when most accidents occur – when moving the waste from a tank to a drum, for example.
  4. Isolate Waste Containers – Obviously, you want to store your waste in a secure, safe area.  Pick a low-traffic area, if possible.
  5. Label, Label, Label – Make sure when you take the time to implement a safe handling of your waste that you properly label all drums, tanks, pallets, etc. The waste hauler and processor will know which waste stream is which. This will allow for a smoother and safer removal and disposal process.
  6. Do not Delay – Dispose of waste in a timely manner.  This action step could certainly be #1 on our list.  Best practices suggest that you not store hazardous and non-hazardous waste at your facility for more than six months.  However, consult your local and state authorities for the specifics of your waste stream.

A great place to start researching is the EPA or DEP. These sites have plenty of information on the latest rules and regulations regarding your waste.

What is Moly?

What is Moly?

Molybdenum Disulfide, simply known as Moly, is used both independently as a dry lubricant and as an additive in lubricating greases. Dry lubricants reduce friction between two sliding surfaces without the need for an oil medium. Dry lubricant molecules have a natural attraction to metal and adhere themselves to metal surfaces. These molecules create a layer of protection that prevents wear and tear as well as significantly improve lubricity of metallic surfaces.

How Does Moly Work?

When used on its own, Moly is impregnated into the surfaces of metal parts to improve the lubricity and protect the parts themselves. When used in greases and lubricants, the Moly attracts itself to the metal surfaces as an anti-wear surface coating. When used in lubricants, Moly’s efficacy is limited if the additive remains suspended. It is important to ensure that the Moly is compatible with the oil or grease. If it is not compatible, the compounds could drop out and plug oil passages and filters.

Moly has a variety of unique properties that distinguish itself from other solid lubricants and solid additives. These include:

  • An inherently low coefficient of friction
  • Strong affinity for metallic surfaces
  • Film forming structure
  • Stability in the presence of most solvents
  • Effective lubricating properties from cryogenic temperatures to 350 C in air
  • Efficacy in vacuum and aerospace applications

Moly Greases

Moly greases can have concentrations from anywhere from 1 to 20%. Typically, Moly greases typically contain 3 to 5% Moly. Moly greases are generally used in operations where high pressure metal surfaces are sliding against each other. These include roller bearings that have very heavy loads and shock loading. Moly greases are also recommended in slow or oscillating motion that is used in universal and CV joints. Moly greases used in high-speed bearings can create problems such as “skidding,” where a bearing roller fails to rotate a full 360 degrees.

Due to its lubricating abilities in vacuums, Moly and Moly greases are popular in aerospace applications. Temperature limitations for Moly are much higher in space (1200 C compared to 350 C in air) thus can withstand extreme temperatures in space. Moly is used for low speed systems such as solar array drives, sensors, and antenna scanners.

Conclusion

As a solid lubricant, Molybdenum disulfide (Moly) serves as a better lubricant and additive than graphite because of its ability to operate under very heavy loads and in vacuum environments. If your machine’s manual calls for a moly grease, it is important to ensure a moly grease is used and the moly grease is compatible with other lubricants in your equipment.
