Reducing GHG emissions using wind-assisted ship’s propulsion

    Industry 4.0, Vol. 9 (2024), Issue 1, pg(s) 17-20

    International trade is still heavily reliant on oceangoing vessels and the noxious bunker fuel that feeds most ships’ massive diesel engines. Although shipping contributes relatively small shares of GHG emissions per unit of transport work, without further action, emissions from the sector would continue to increase. Therefore the maritime community and ship-owning companies are attempting to achieve “green shipping”. The revolutionary technology to use the wind for assisting the ship’ propulsion is one of best steps for decarbonisation of shipping. This innovative technology could bring considerable reducing fuel consumption and cost savings, improving the ships efficiency as well. There are different ways to utilize the wind power, as several kinds of rotors, sails, kites, etc, some of them already installed on commercial ships, some are still dreams. The aim of this paper is to present the basic essence of wind-assisted propulsion and the environmental impact of its use.

    Industry 4.0, Vol. 6 (2021), Issue 5, pg(s) 197-200

    Protecting the environment is vital to keeping life on the planet as we know it. Climate change is a global challenge with a clear complex nature in various aspects – environmental, social, technological, economic and political. At the international and national level, climate change policy is implemented mainly in two directions: 1. climate change mitigation through measures and activities to reduce greenhouse gases and 2. adaptation to the inevitable climate change by assessing risks and mitigation activities of their imp act. Implementing these policies requires investment in new technologies and the integration of climate challenges into green sectoral policies at national and local levels.The purpose of this report is to study the state of environmental indicators for Bulgaria and their development dynamics over the last decade. The results reveal the sectors with the strongest influence on the ecological condition of the country an d the directions for its improvement.

    Innovations, Vol. 9 (2021), Issue 4, pg(s) 134-136

    The subject of the article is organizational conditions of creating and developing energy clusters in Poland. The aim of energy clusters is the development of distributed energy. They are used to improve local energy security in a way that ensures economic efficiency, as well as in an environmentally friendly way by providing optimal organizational, legal and financial conditions. Energy clu sters also allow the use of local resources and domestic energy potential. The effectiveness of energy clusters depends on the rational and effective use of potential, i.e. locally available energy resources, renewable energy sources, innovation, entrepreneurship in the area of man ufacturing, industry, distribution, as well as management of energy consumption. The aim of the article is to analyze the formal conditions of clusters, in particular the essence of their existence, the tasks that the cluster performs and the role of key cluster participants. As a result of this paper the autor shows the the process of creation and functioning of a energy cluster.


    Effective determination of clomazone and oxyfluorfen in aqueous samples by differential pulse stripping voltammetry

    Innovations, Vol. 9 (2021), Issue 2, pg(s) 63-65

    Two novel types of electrochemical sensors were obtained by chemical deposition of Pt and MoO2 nanoparticles onto multi walled carbon nano tubes (MWCNT) and used for determination of frequently used pesticides clomazone and oxyfluorfen in aqueous media via differential pulse stripping voltammetry (DPSV). Clomazone was determined in 0.1 M phosphate buffer solution at pH 7.0 in the concentration range 0.61-20.56 ng cm-3, with LOQ = 0.61 and LOD = 0.38 ng cm-3. Oxyfluorfen was determined with good reproducibility (RSD <2.4%) in the concentration range 2.5-34.5 ng cm-3, with r = 0.99 and a LOQ of 1.5 ng cm-3. Results were in the same range measured by HPLC/DAD, which was used as comparative method. Structural characterization of the dopped MWCNT performed by Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron (HR-TEM), and X-ray crystallography revealed a preserved MWCNT structure decorated with well dispersed species of the platinum and MoO2 nanoparticles

  • Criteria for wind energy projects’ location assesment

    Science. Business. Society., Vol. 4 (2019), Issue 3, pg(s) 82-85

    Insuring a sustainable development of wind energy production and consumption is challenging and highly important for /achieving of EU 20/20/20 goals for Bulgaria. Wind energy has been seen as a clean and environmentally friendly in comparison with conventional energy sources, but there are still some conflicts between wind energy project development and environmental protection goals that should be enlighten and solved. One possible way is to enhance the process of wind energy projects’ location identification. The current research is focused on identification and classification of criterion that could be used in this process. The legal requirements regarding wind energy projects’ location are analyzed and presented. Additional requirements regarding environmental protection and biodiversity conservation are identified and defined as criterion. A set of measurable indicators related to each criteria is established and proposed in this paper.

  • Transport and environment: Need for sustainable solutions

    Trans Motauto World, Vol. 4 (2019), Issue 1, pg(s) 24-27

    Transport has irrepressible contribution for the effective development of economy and society. But, these contributions are exceeded by harmful environmental consequences that transport growth causes especially in urban areas. Air pollution, acid rain, noise, climate change are just few of the problems which every urban area is dealing with. Hence, it is very important to provide development of the transport that at the same time could increase its sustainability and minimize environmental degradation. Numerous sustainable transport solutions are available with a potential to decrease these negative influences and promote mobility with higher sustainability. This paper presents a review of sustainable solutions, successfully applied in practice, as guidance for those urban areas that are dealing with the environmental problems from transport, but still are a step behind in undertaking activities.

  • Best practices in CBRN waste management in military operations

    Security & Future, Vol. 2 (2018), Issue 3, pg(s) 130-133

    Dangerous wastes are solid, liquid or gaseous materials that may be lethal or dangerous to humans and the environment. Such wastes can be toxic chemicals and flammable or radioactive substances, including industrial waste from chemical plants or nuclear reactors, agricultural waste, pesticides, fertilizers, medical waste or hazardous household waste such as toxic dyes or solvents. CBRN waste should be safely recycled without harm to the environment. Toxic chemicals, radioactive substances or biological materials should be concentrated for final disposal.

    The parallel functioning of strategies for innovative and sustainable development leads to the emergence of a formal methodological paradox in the form of increasing negative technological impact on the environment due to the prevalence of economic criteria for assessing the efficiency of production over social criteria. This paradox determines the permanent growth of products that can be combined with the concept of waste. To eliminate the methodological paradox, it is necessary to implement the ecological imperative by greening the legal framework that regulates all stages of the life cycle of innovative products.

    The expansion of our needs in the space and many changes around us requires a change in attitude towards the environment. Research suggests that by 2030 in the world there will be 8.5 billion people. Planet is warming up and there is an increasing frequency of natural disasters: heat waves, floods, hurricanes. The public is aware that air pollution kills 3,3 million people per year. It is necessary to react quickly. In Paris at the end of 2015 the 21-st Conference of the UN on climate changes (COP 21) was held.

    Serbian association of importers reported that in recent years in our country about 20.000 new cars and about 100.000 used cars was imported. In Serbia there is no laboratory that could to accurately test the amount of exhaust gas according to European standards in effect. In our country still is in force the Regulation on technical inspection from 1984, so the allowed values of exhaust gases are completely downgraded. Today, in our capital city Belgrade we have been working on the improvement the identity of capital, as well as mobility and ecology. In 1892. in Belgrade the first Belgrade’s tram – by a horse-drawn started, but during 2016, passengers will be transported by 5 electric buses of the Chinese company “Hager” with 10 years guarantee.

    Hoping to realize the idea of manufacturers from all around the world, especially that pollution is reduced, and the environment in which we live protected, this work originates.
