Any waste collected by or on the order of municipalities falls under the definition of what a MEMIOS system can transport through its system. According to the Organization for Economic Co-operation and Development (OECD), municipal waste is "waste from households, including bulky waste, similar waste from commerce and trade, office buildings, institutions and small businesses, yard and garden waste, street sweepings, the contents of litter containers, and market cleansing waste."
All MSW waste such as papers, plastics, cans, glass etc can be deposited and transported by the MEMIOS system. Typically standard household and commercial/residential waste can be conveyed through the system.
Large furniture, appliances, heavy metal objects, dangerous or illegal chemicals or liquids.
No hot coals, lit cigarettes, flammable oils (such as fuel oils, kerosene, gasoline, motor oil etc.), portable and disposable spray cans, etc.
Large foam cushions or blocks of foam, etc., which can expand and block the transport pipe.
The collection terminals can be designed in several floors. They can also be entirely above ground, entirely underground and semi-underground/over ground.
The pipes are protected with a PE-coating which is normally enough for the installation in trenches. In the case of bends other types of external coatings can be also used, but always according to international standards.
Corrosion of the pipes may appear if they are installed in corrosive environments. In these cases we install anode or cathode protection. This gives sufficient protection and is considerably less expensive than using stainless steel pipes.
Yes, the pipes that MEMIOS use are prepared to be installed directly in the ground independently of whether they are below the water table or not. The pipes have a special external protection: a 3 layers polyethylene coating. We are using exactly the same protection as the gas pipes, in accordance with European standards, when the pipe is installed in the ground.
We have a number of installations where the pipe is located below the water table. Some of these installations were built more that 20 years ago and are still in very good condition.
