Tree innovations: from a bioretention system to sandwich constructions


Have you been researching alternative ways and solutions for tree planting in urban areas? Then it could be helpful to request aid from expert tree planting companies to establish the best solution for your urban area. Due to the intricate infrastructure and underground utilities such as subways, it is hard for trees and other greenery to thrive in urban city environments. It is no exception that trees die when their roots have insufficient growing space to expand or they have insufficient quantities of water to stay alive. In addition, roots may cause excessive heave, which leads to damaged pavements. Next to the problems with establishing thriving greenery in the urban environment, stormwater management is also rather unusual, as massive concrete does not absorb and runoff water as quickly as regular soil. But what can cities and its governors do in order to solve these problems?

What kind of solutions are possible?

One of the answers is to ask the help of an expert, such as Treebuilders. You might wonder what kind of solutions are available when asking help from tree planting companies. Next to innovative bioretention systems, Treebuilders has many more designs to maximize the effectiveness of water and tree management in urban environments. Think about their pressure system, called the sandwich construction, that increases available root growth volume. Thanks to the innovative solutions of tree planting companies such as a bioretention system, trees are now able to thrive and mature in urban environments and exist harmoniously and in balance with the local infrastructure and utilities.

The chemical composition and minerals


Each mineral has its own unique chemical composition and internal structure, with which the atoms are arranged within the crystal lattice. The crystal lattice determines the shape and fission of the crystals that make up the mineral. In some crystal lattices the atoms are closer together than in others, these minerals are denser. Minerals with the same chemical composition are called polymorphs. Diamond, for example, is a polymorph of graphite, both minerals consist of pure carbon, but diamond has a denser crystal structure. Under high pressure, graphite can convert to diamond, such a transition from one polymorphic to another is called a phase transition.

Chemical composition
Which minerals are present in a rock depends in the first place on the chemical composition of the rock. A rock that contains enough silica (SiO2, the oxide of the element silicon) may contain quartz or another mineral consisting of pure silica. The rock-forming minerals consist almost exclusively of nine elements (silicon, sodium, potassium, aluminium, oxygen, hydrogen, iron, magnesium and calcium). Together, these elements make up 98% of the total mass of the continental earth’s crust.

Most rocks consist mainly of silicates, minerals that contain silica. Almost all coagulation rocks and most sedimentary and metamorphic rocks are included. An important exception is carbonate rock, which consists of carbonates (compounds of carbonate, CO32-). Examples of carbonate rocks are limestone, marble and dolostone. There are other exceptions, such as halite (rock salt) and gypsum are also not silicates.

This breccy is an example of a clastical rock in which the cliffs (dark) of the matrix can be clearly distinguished. Because the cliffs all consist of the same limestone, the distinction is sharp. Location: slope of the Devínska Kobyla in the Slovakian Small Carpathians. Age: Early Jurassic.
Two rocks with the same chemical composition do not have to contain the same minerals. Whether a certain mineral could be formed in a rock depends on the temperature and pressure that prevailed in the rock and the composition of any liquids that flowed through the rock.

Some rocks consist exclusively of minerals, the crystals of which have grown together, they are crystalline substances. However, there are also rocks that consist of fragments of minerals or dead organisms. Such fragments are called claws and these rocks are called clastic rocks. Examples are sand (and sandstone), clay, conglomerate or breccy. Some clastic rocks consist of very different claws: pieces of different types of rocks or minerals, fragments of shells, plant remains or fossils. However, there are also clastical rocks in which all or most of the claws have the same composition.

An important concept when describing rocks is the texture of a rock. This refers to the external properties on a small scale, which are present everywhere in the rock. In the case of a crystalline rock, this includes, for example, the size and shape of the crystals; in the case of clastic rocks, this includes the size and shape of the cliffs. Also important is how much volume is taken up by claws and how much by the matrix (all the material in between the claws).

Some rocks have minerals or cliffs that are predominantly in a certain direction. Whether and how strong this is the case is called the “fabric” of the rock. The product is part of the texture of a rock.

Rock destruction

A soil profile indicating soil horizons. The O-Horizont consists of organic material, which has become humus in the A-Horizont. Due to leaching from the upper O-horizont there is little left of the parent rock in the B-horizont; in the C-horizont the parent rock is still visibly present, although it is weathered. Under the C horizont is then the bare parent rock (R).


The natural degradation of rocks is called weathering. Weathering occurs through chemical, physical and biological processes. Physical weathering includes, for example, rock fragmentation due to freezing of water (frost weathering).

It does not change the chemical composition of the rock, but causes it to disintegrate into smaller pieces. Chemical weathering occurs when rocks come into contact with the atmosphere or ground water so that chemical reactions take place and the chemical composition of the rock changes. Certain components of the rock can be dissolved and removed. Biological weathering is all weathering as if it were

The woods dual power Car and the amount of success


Up to 1918, 600 examples were built. The Woods Dual Power was not a commercial success. It was too expensive and drove too slowly compared to the conventional petrol car. In addition, the maintenance of the hybrid propulsion was expensive.

In the period after the Second World War until 1990 there have been several developments in the technology of both hybrid and electric cars. Such as the regeneration of electrical energy during braking for charging the batteries. Electronic circuits were also used that provided for intelligent cooperation between the petrol engine and the electric motor in the event that more or less power was required. These developments were mainly for small-scale experiments and were encouraged by governments in America, Europe and Japan with the aim of making fossil fuel cars more economical and reducing harmful emissions.

Carparts Expert offers carparts for good prices and with a great service desk. You can find more information about Carparts Expert on the website of Carparts Expert.

The real breakthrough of the hybrid electric car came in the late 1990s. To respond to the public and political desire to reduce fuel consumption (CO2 emissions) and pollutant emissions from combustion engine cars, the Japanese car manufacturer Toyota Motor Corporation decided in 1997 to launch a gasoline-electric hybrid car on the market. 

It became the Toyota Prius, the world’s first mass-produced hybrid car. Initially only available in Japan, the Prius became available in the U.S. and Europe in an improved version in 2001. Initially sales were slow, but from 2003 when the second generation Prius appeared (type XW20 see photo), the model became more popular in both the US and Europe.

Shortly after, other manufacturers had also introduced a hybrid car to the market, including the Honda Insight. HEV’s get a clear position in the market and until now there are more and more manufacturers that provide their models with hybrid propulsion. The development of the all-electric car and the plug-in hybrid car, a HEV in which the battery can be charged with a plug, has also taken place.

An important negative factor of the HEV is the relatively high purchase price that is caused by the high production and development costs. The government’s incentives are therefore a major support for the sales of HEVs. When purchasing a hybrid car, one receives a purchase premium or the car is (partially) exempt from purchase or use tax, as in the US, Canada, Japan and a number of countries in Europe, including the Netherlands.

Since 2008, due to economic decline, unstable oil prices and the environmental issue of global climate change, there has been a great need for new innovative developments in the Western world.

In general, it is considered that the greenhouse gas CO2, caused by human activities such as the combustion of coal and gas in power stations and the use of petrol and diesel for cars, plays an important role in global climate change. In addition, people are also aware that the availability of fossil fuels on our planet (such as oil, gas and coal) is not infinite.

It is difficult to predict future developments to attract the economy and solve the climate problem. How long will the conventional car with petrol and diesel engine continue to exist? To what extent will the hybrid car and the electric car replace the conventional car? Will there be a whole new development? Today’s society cannot be compared to that of the early 1900s, when the Lohner-Porsche Mixte Hybrid was driving around. In the coming decades it will be determined which direction will be taken for the automobile but also for mobility in general. However, history has taught us that major changes are possible, as is the step from the horse-drawn carriage to the automobile of today.

Land transport is as old as history. First, pack animals were used, then the invention of the wheel, which made it possible to use carts, both for transporting goods and passengers. The luxury version of the cart became the carriage. This was gradually improved over the years, first with suspension systems and later with the addition of brakes.

The discovery of steam power at the beginning of the 17th century led to the invention of several machines, including ventilation pumps used in English mines. Many inventors tried to use that steam power to propel themselves.

The first to do so, as far as we know, was Père Verbiest, a Belgian Jesuit who lived as a missionary in China at the end of the 17th century. He built a scale model of a steam-powered cart. The Emperor found this extremely amusing, but the project was never carried out.
