Subject: Asphalt Shingle Recycling
[snip]
In July of this year, a firm that I represent as sourcing coordinator will
begin production of a totally recycled-content asphault shingle product.
The company's name is Inovate (one "n") and they are based in South Gate,
a city which adjoins the commercial andn industrial center of Los
Angeles. the owners are two guys who made their first fortune making a
product known as the "Dura-ridge," an angled composite shingle that is
placed on the ridge of roof-lines and revolutionized the composite
shingle market when it was introduced in 1977.
The new Inovate product can only use tear-off from totally asphault
roofs--the rocks have to be "spudded" off the surface, and the tolerace
of wood into the product, while acceptable, is relative low--less than 5%
of the total material recycled. What happens in our process is that old
shingles are shredded and then dropped into a steam jacket, where the
asphault melts and becomes a sticky, gooey substance that is then
extruded, formed, and cut in a continuous process. mGiven the
Dura-ridge's market share when the patent lapsed last summer, Inovate
hopes to begin licensing this process sometime in 1998.
If you have any questions, you can call me in my office at 805-240-3448.
