Ubuntu-blox block’s latest version is now ready

The original Ubuntu-blox was made with all kinds of plastic trash into a block with a two wire restraining feature.  We realized that a third wire was needed in the middle between the two outside wires and modified the machine and process to accommodate that concept.

We made the blocks then with all kinds of plastics and the three wire retaining system.  It was about that time we were asked by Stephanie Hunt of the Hunt Institute at Southern Methodist University to build a house using Ubuntu-blox for the their Engineering and Humanity Week of April 2011.

As we thought about the house to build for the Hunt Institute we realized that using all kinds of plastics meant we were creating a diversion from successful existing plastic recycling programs in North Texas.  Curbside recycling was already picking up bottles and all plastics except for foam and film plastics.  Foam and film plastics were not being recycled in what we felt were honest recycling programs.  We decided to use foam and film plastics in our blocks for building the Ubuntu-blox house for the Hunt Institute’s Engineering and Humanity Week.

That combination of the single purpose shopping bags, the ones that are so popular now in the banning industry, and foam plastics readily available have shown to be the most cost effective method of building the blocks.  Each block contains approximately twenty to thirty film plastic shopping bags and three cubic feet of foam plastics.  The only cost for materials for the block is the wire retaining the block shape and providing the attachment system for making the walls.  The cost of the wire was less than twenty cents per block.

When I got to Haiti August of 2011 I found out that the single purpose film plastic bags were not available in the quantity needed for making  the blocks.  There was an unbelievable amount of foam plastics available in the form of dinnerware, trays and cups, but a very limited amount of film plastics.  We had access to some rice bag material also known as sand bag material.  It was in bulk because it is what is used in Super Adobe construction.  We could cut the rice bag material in five foot lengths, fill it with shredded foam plastics, and make a great Ubuntu-blox.

I went back to Haiti March of 2012 and we used the rice bag material and the wire to make the blocks.  One of the heart breaks for me during that visit was watching the Haitian ladies straighten twisted wire we were getting for free from a recycling center.  They spent as much time straightening out the wire as they did making the blocks, maybe more.

There was also another reality, cost. Purchased new the wire cost about twenty cents per block.  The rice bag material cost another fifty to sixty cents per block.  We had an awesome block but it was out of line cost wise.

When I came home to Texas I purchased some electrician pulling line to see if it would work as well as the wire for retaining the block shape.  It does.  The cost is considerably less and it is a lot easier to work with.  The cost of the block was still way too high, fifty to sixty cents per block for the rice bag material, and the cost of the string was almost ten cents per block.

One of the experts and a good friend in the pursuit of making the world a better place is Patti Stouter.  Google her and be impressed.  She has been after me to look at other materials for making the blocks besides the rice bag material.  The biggest obstacle in finding a suitable substitute that was available in the amount required was it seemed all to come out of the far east.

Sheer happenstance provided me with a local manufacturer here that could not only provide me with the line I needed but they also manufactured film plastic tubing in weights and diameters I could use.  Using their materials I can now make a block with a cost of less than fifteen cents.  That’s for the line for retaining the block shape and a tubing for containing the foam and film plastics.

If you take best case scenarios using rice bag and wire in Haiti to make the blocks you are looking at $195.00 to make a 150sf house using 300 blocks.  Using the new materials that cost is $43.50.  That is $150.00 per house savings.

BAD Plastic blocks!

We’re making blocks for an event in April.  They want us to have a model house for attendees to experience.

The guys and gals at Allied Waste Recycling Center in Plano, Texas will give me all the plastic I want to make the blocks.  That is too easy and doesn’t make a loud enough of a statement.  All of the curbside recyclers, Allied Waste included, won’t knowingly take styrofoam or film plastics.  Stryofoam and film plastics are destined for the landfill.  If it is put into the recycle bin for curbside recycling it is sorted out and shipped from there to the land fill.  Unless I find it first.

I wade into that stuff and I pull out the styrofoam.  It takes almost a full large garbage bag’s worth to make one block.  They don’t always have it.  But if they do and I’m there I get it, as much as I can.  I stop at a couple of groceries that allow me to pick up the contents of their recycled plastic bag bins.

This is one morning’s haul.  The styrofoam is in the big green bags and the clear bags are full of film plastics from the grocery stores.

The fun starts at the shop.  I take the grocery bags and put four of them together.  Then I fill the bag with pieces of stryofoam.  When the bag is full I tie the ends together, just like they do at the store when you use the bags for your purchases.

The styrofoam won’t stay together as a block without being contained in the bags.  It’s almost serendipity the way it works.  One bad plastic won’t become a good thing without the other, marvelous.  I’ve also found out that one or two of the bags isn’t enough to hold the styrofoam in place during the compaction process.  So we use four bags.

It takes four bags full of styrofoam to make a half block, six to make a full one.  Believe it or not, I ran out of the grocery bags today before I ran out of styrofoam material today.  I also pack in the big pieces of film plastic I get like the shrink wrap and large plastic wrappings and bags thrown away.

This is a large block ready to wire up.

I’ve put in a plea for clean styrofoam dishes like plates, trays, cups, egg cartons, etc online at different places.  I wanted to get some newspaper coverage with a plea for that stuff but it didn’t work out very well.  So if you look up recycling styrofoam in Dallas, Texas hopefully during your search you will find my begging for the bad stuff.  I need about three hundred large bags full for the model house, sorry landfill, you lose, we win.

A Plea for help

We have been honored by an invitation to display at a very important event in Dallas in April.  As of right now we plan on having a finished shelter designed by Ronald Omyonga.  He will design and we will build an example of a shelter made for Nairobi Kenya.  We also want to have at least one plastic block press onsite with materials for visitors to participate in making recycled plastic blocks.

As most of you already know styrofoam and film (grocery sacks) plastics are not wanted for traditional recycling.  At most recycling centers that handle home pick up recycling these items are sorted and then sent to the landfill.  Allied Waste aka Republic Recycling center in Plano Texas will give me recyclable plastics for the blocks.  I don’t want to use that because I want to use the stuff that is destined for the landfill.

That’s where I need help.  If you live in the north east of Dallas area, close to Wylie, and you want to participate I want your film plastics, grocery bags etc.  I also want your clean styrofoam stuff.  This can be anything from peanuts used in packing, the big foam blocks that protect electronics during shipping, to go foam dishes and cups, foam and film plastic packages for groceries like meats and vegetables, and let’s not forget those foam egg cartons. 

I want them clean if at all possible.  It won’t take you but a minute to rinse them off before you bag them for me.  The reason for that is the blocks made with these products will be handled by the public, specifically college students. 

As more information becomes available we will pass it on about the event.  It is an unbelievable opportunity for us and we want it to take full advantage of the exposure.  If we can build the shelter and demonstrate with stuff destined for the landfill because it doesn’t already have recyclable value it will be even better.

One more thing, we get about two  to two and a half blocks from each large green plastic trash bag of material.  If you want to see the process and participate making blocks we would appreciate that help too.  Especially if you bring along the kiddos.  That would be the best thing of all, starting them young to be responsible consumers and citizens. 

One other thing while you’re feeling so generous, I want to share some of these blocks with the public for them to use to share the vision of making homes for the third world that are good homes.  Not just shelters, homes.
