“…An apparent density value was obtained for briquettes produced from the coconut shell of 0.98 g.cm -3 , where these results referred to the literature data show that the briquettes produced have a relatively good density, which is important in the logistic aspect (Dziedzic et al, 2018). In general, there is a tendency to increase the apparent density with the increase of the epicarp percentage in the composition of the briquettes particles.…”

The macaúba palm (Acrocomia aculeata) is a palm-seed-oil producing tree of great economic value for its high productivity, and the broad range of possible uses for the different parts of the plant. This palm is one of the most promising species for the production of biodiesel, however, its use generates large amounts of waste. The aim of this work is to produce and evaluate the quality of briquettes made from the epicarp of the macaúba palm, in association with the waste of the Pinus sp. For the characterization of the residues, the following analyses were carried out: bulk density, immediate chemical composition, and higher calorific value. Different treatments were adopted in the production of the briquettes, namely: T1 (100% macaúba palm), T2 (75% macaúba palm + 25% pine), T3 (50% macaúba palm + 50% pine), T4 (25% macaúba palm + 75% pine) and T5 (100% pine). The briquettes were produced at a pressure of 1000 PSI, and at a temperature of 120-130 ºC, press and cooling times of 5 minutes, and an average humidity of 9.88% for the macaúba palm and 8.00% for the Pinus. In order to qualify the briquettes’ dimensions, the following were evaluated: apparent density, rupture load, lower calorific value, useful calorific value and energy density. In general, mixing at least 50% macaúba epicarp is recommended to produce briquettes, as this material provides increased strength and energy density to the product.

“…Then the second member in (14) can be ignored and finally get the formula for the relative speed of the seedling. (15) We use (15) in order to obtain an equation that groups together the dynamic coefficient of vibro-viscosity and physics and mechanics characteristics of the cuttings. Then we apply the equivalence principle of pulse resistance forces to cutting movement in different mediums [10].…”

When we design the automated systems of unloading materials from the tankers, especially when we construct the automated tool for planting an energy willow, there is a need to create the movement model and to study its characteristics. The combination of cuttings, unloaded from the tanker, can be represented as the flow of a two-phase pseudo liquid. Then the process of unloading itself can be modelled on the basis of methods of hydrodynamic multiphase systems. The main characteristics that affect the process of unloading are highlighted in the deduced equation. The effective coefficient of vibro-viscosity and the calculation algorithm for the dynamic coefficient of vibro-viscosity in terms of cuttings oscillatory motion influenced by gravity field and harmonic vibrations is given in the study.

“…Improving efficiency is key to both creating competitive prices and making better use of suitable land. Improvement may include identification of fast-growing plants, successful reproduction and use of crop combinations, new knowledge of plant cultivation and biotechnology, which may increase plant productivity by 5-10 times compared to their natural capabilities [7][8][9][10].…”

At the beginning of the third Millennium, humanity is forced to face a new surge of tensions and contradictions between different countries and peoples, between different parties and faiths, as well as the growth of environmental, economic and social problems both in different regions of the world and on a global scale. These phenomena are the result of the exhaustion of socio-economic forms of development of society within the existing natural resource and environmental conditions. An increasing number of people and states are experiencing an acute shortage not only in quality food, but also in quality water, clean air, energy, land, biological and other resources. After all, according to some scientists over the past hundred years, the consumption of natural resources by mankind has increased almost 100 times. For the first time in the history of mankind, resource and environmental crises have reached the biosphere borders and there is a danger to the existence of civilization. Humanity faces a global challenge, the correct solution of which will result on the lives of our descendants in the future. The common task for all is to preserve the biosphere as the habitat of mankind. Further increase of material and energy flows becomes impossible, as well as further satisfaction of the needs of new billions of people who will be added to the total population. Humanity is on the threshold of a new socio-economic formation, as neither a centrally managed economy nor a market economy has been able to solve the global environmental problems of our planet.
