People who live on islands (like Puerto Rico) have limited land. As a result, it can be difficult/costly to get rid of trash (which would normally be sent to a landfill).
One way to deal with it is to convert it into building materials by turning it into "trash rocks", as Puerto Rico inventor/artist Bill Birdsall aka Thinkenstein describes below.
Birdsall makes other cool thing as well. Do a search for "Bill Birdsall nylon cement" for a link to his web page. (Which FB doesn't like for some reason.)
