bio-degradable screen that helps slow erosion?

Question

in talking to a farmer about an area of my lawn that has at a very steep slope, trying to plant a ground cover that will help stop the quickly eroding soil, he mentioned a bio degradeable screen that is used by highway depts to help small plants, grass seed stay put while germinating and getting past the first growing season. dont know the official name of this product, but looking for any ideas as far as what it is called, and where to purchase. he said once my plants have had a chance to take hold, the screen will bio degrade. any help is appreciated..
thanks

if you have any suggestions on a rather invasive ground cover, that does ok in clay, gets morning sun, and flowers for a few months, will be happy for that info too..
thanks again

Aluminum has ALREADY been broken down. the skill of refining aluminum ore is taken into consideration one of extracting the steel from the compound that exists in nature. Over a volume of time, the foil will oxidize and revert returned to its organic kind. this would take centuries because of the fact the oxide layer that varieties on the floor of the aluminum is air-tight and forestalls to any extent further oxygen from achieving the uncooked steel.
