Well the purpose of a fence is mostly to keep people (or animals) in or out.
I figure, maybe there was technology we use in recycling that could be considered an industrial secret or that they didn't want people dumpster
diving in the area- therefore the fence should face outwards.
Therefore the logical conclusion would be the containment of stray animals who may have come in to contact with chemicals or other wastes to prevent
contamination of the local ecosystem.
Sorry, haha I just have a curious mind here lol!
