One of the most common comments I get are about the use of the wire in making the block. Usually heat or chemicals are suggested to make the block without the wire.
That is being done. Peter Lewis in New Zealand is an aeronautical engineer and licensed architect. Mr. Lewis has millions of dollars and about twelve years invested in his Byfusion system. Watch the videos, read the story, you will be impressed. A small Byfusion recycling machine will cost about $600,000.00 US. It takes one kilowatt of electricity to make one block. When volume is a consideration the Byfusion system is probably the most viable one out there. Peter Lewis is a genius.
Our manual machine makes a compressed plastic block without any electricity or petrochemical fuels. It transforms seven pounds of plastic trash into a seven pound building block, ten pounds of plastic trash into a ten pound building block. There is no waste or loss of material in the compressing of the plastic into a recycled plastic building block. It is one hundred percent efficient, ounce of trash, ounce of building block, no carbon based energy consumed.
I woke up from a sleep baling plastic blocks with wire. That’s not genius. That’s dreaming. As I thought about it I realized that wire not only was perfect for holding the shape of the block, it also presented the best method to form a wall with the baled plastic blocks. A couple of things need to be considered here. One of them is my mind wasn’t working in a vacuum. I knew wire was used to bale hay and straw. The other was I knew wire was used to help hold bales of straw together in strawbale houses. Wire is also used to strengthen earth bag houses.
I appreciate that the recycled plastic block construction concept is difficult for most people to grasp. That’s because most people aren’t familiar with earthbag home construction, strawblale houses, and compressed earth blocks for housing. Those who are familiar with those methods of building shelters understand the recycled plastic block is another variation of what has been done to build shelters since mankind left caves and needed protection from the elements and predators.
The alternative to wire is either a mortar like conventional concrete and stone walls are put together. Or there is the mortise and tenon fit method that offers a mechanical connection. Byfusion and Oryzatech use that approach. Oryzatech also uses a contact type cement as I understand it. So it uses the mortise and tenon and mortar approach to stack blocks to make walls.
I wasn’t able to form the recycled plastic blocks where the mortise and tenon approach would work. Using all seven grades of plastic trash ruled out the use of a polymer answer to connecting the blocks in a wall. So I was stuck with wire and re-bar.
This turned out to be a very good thing as I see it now. The wire provides a more flexible connection than mortar or mortise and tenon connections do. It also provides a stronger connection. The wire method allows more creative shapes and designs of walls without sacrificing the integrity of the connections. The wire connection I believe is in our genes too. Before we stacked rocks I’ll bet we were tying limbs and grasses to make shelters.
The wire is what makes this system work. It holds the shape of the block during and after it is placed in a wall. The durability of the galvanized wire has been questioned. The link suggests that it will last inside the wall almost as long as the plastic used to make the block. It simplifies the construction process labor and material wise. It takes less skill to build a shelter with wire than it does to lay a concrete block wall with mortar. Concrete and mortar usually use cements that are not made locally. They also consume petrochemical and electrical energy to produce, transport, and to build with.
