Even the construction sector becomes greener every day, or at least a part of it, and it can be seen by reading the many alternatives discovered for traditional brick. We call them ecombricks, do not always ensure the same performance as traditional bricks, those constituted from a mixture of clay and water, but work can be done to arrive at at least partial replacement in the future.
Soon we will find out what we have invented so far by reusing the waste materials to produce bricks that could be comparable to those we have always been used to using. Obviously the change will not be fast, and maybe not even total, but already being able to replace part of the bricks with eco-bricks could have a strong impact from an environmental point of view. Even in our country, yes, which, although small, is definitely very built especially in areas such as the Po Valley, or around the capital.
The dough with which the classic brick is prepared has a plastic consistency and takes the size we want, it is baked in the oven until it is solidification and has essential mechanical characteristics. With eco-bricks we try to reach a result comparable with other materials, starting from straw and wood, from paper mill waste, from hemp, from recycled television glass. If you see some beautiful!
The more research advances, the more confidence in the green building which can give us satisfactions both in terms of energy savings and raw materials. If we are able to use industrial waste, we also affect their disposal by contributing to the resolution of the environmental problems that are related to it. This is the case with the eco-bricks of paper that we are going to illustrate. Searching and searching, you will discover that various experiments are also underway with other types of waste, with those of beer, for example, or oil.
Ecomattoni from paper
It all started inExcuela Polytechnic Superior de Linares of the Spanish University of Jean and dream of a team of researchers who thought of obtaining bricks by working the residues of cellulose from the paper produced in paper mills. Not trivial as a challenge, especially due to the need to carefully test both the physical and mechanical properties of this innovative material.
These Spanish eco-bricks are obtained from sludge deriving from the purification of waste water from a paper mill and from the residues of cellulose cleaning processes. The researchers identified the right mix of these materials and combined it with clay, which is normally used to produce bricks . The result was cooked in the extrusion machine to obtain bricks which, in addition to saving us raw materials, also allow us not to waste energy or even time, because cooking is much shorter. The eco-bricks made in this way seem to work and are also good thermal insulators, however there are aspects to improve, such as that of lower mechanical resistance.
Ecombricks of hemp
Even the much talked about hemp can be a base with which to produce ecological bricks, mixed with lime. The result is a material capable of capturing CO2 emissions and guaranteeing excellent thermal and acoustic insulation. Not a bad start, even if there mechanical strength is not yet comparable. Meanwhile, hemp is used, even in Italy, alone, as a coating for interiors and exteriors, as well as furniture, in the form of tiles that are certainly not able to support a house.
Ecomattoni of straw and wood
It is not recent the news that it is possible to build wooden houses with economic, environmental and social advantages. This material could revolutionize the sector, more than others, more certainly than straw which, however, was used by some brave to make an entire house. The result is almost totally recyclable or biodegradable but for now we certainly cannot think of replacing the brick with straw.
Ecombricks from plastic
By recycling some industrial waste materials, we can get to eco-bricks that are closest to the performance of traditional ones. We have already seen this with paper, now we can cite the example of plastic that is certainly not lacking in our industrial supply chain. Today we can for now tell about experiments byecbig men made by recycling plastic bags, a resistant material that lasts over time since these bags, dispersed in the environment, remain for almost a century.
Ecomattoni from glass
Similar to the previous case, that of glass is an interesting and very imaginative example. He tells us that it is possible to obtain bricks starting from the glass with which the screens of our televisions were produced. Who would have thought that? IS not only televisions but also computers because a sort of ceramic is obtained which would seem to have what it takes to give life to a resistant material and mechanically suitable for the purpose.
Bricks for birds
In a crescendo of disbelief, let's now find out what a couple of women, one Italian and one Romanian, Micaela Nardella and Oana Tudose have invented. They called them Brick Biotope and these bricks are not "eco" but also bird friendly. Exact. They perfectly meet the criteria of green building but have a unique feature at the moment. Once placed in a building, they offer an ideal habitat for small birds that usually nest in building niches.
