Jump up ^ Specter, Michael (22 June 1992). "Only in New York: Garbage Disposers, Banned, Stir Debate". New York Times. Most major cities banned garbage disposers after World War II, driven by worries that ground food would clog sewer pipes beneath their booming neighborhoods. ... But a series of studies from universities and the not completely disinterested plumbing industry showed that the additional waste from ground food scraps would rarely harm a city sewage system.
Most modern kitchen sink drains are this dimension--both on the garbage disposal side and the "rinse" side. These are well made items that work very effectively. Unlike most kitchen sink stoppers that rest on top of the drain opening and extend upwards into the sink when you're doing dishes, these fit down into the large opening and seal the smaller opening above the garbage disposal or "rinse" sink drain strainer. In other words they seal the drain without extending upwards into the sink full of water.
In recent years, various Camorra clans have been forming alliances with Nigerian drug gangs and the Albanian mafia, even going so far as to intermarry. For instance, Augusto La Torre, the former La Torre clan boss who became a pentito, is married to an Albanian woman. It should also be noted that the first foreign pentito, a Tunisian, admitted to being involved with the feared Casalesi clan of Casal di Principe. The first town that the Camorra gave over to be completely governed by a foreign clan was Castel Volturno, which was given to the Rapaces, clans from Lagos and Benin City in Nigeria. This allowed them to traffic cocaine and women in sexual slavery before sending them across the whole of Europe.
One result is larger amounts of solid residue from the waste-water treatment process. According to a study at the East Bay Municipal Utility District’s wastewater treatment plant funded by the EPA, food waste produces three times the biogas as compared to municipal sewage sludge. The value of the biogas produced from anaerobic digestion of food waste appears to exceed the cost of processing the food waste and disposing of the residual biosolids (based on a LAX Airport proposal to divert 8,000 tons/year of bulk food waste).
This new one some how makes it quiet when using the disposal. I have no idea how old the other one was, it was here when we moved in. It was flimsy and would let dirty water come up. Cleaning the splash guard and the drain it went into didn't help at all. The new is firm and sits in the drain level. My daughter was putting the old one slanted some to keep it in there. After 2 1/2 years it was falling apart. I wish I'd bought one when we first moved in. This is the first garbage disposal for me but now I've learned what to expect from it. I recommend this product and will buy another if I'm still here when this one starts to get flimsy!
