Identifikace potenciálních příležitostí v cirkulární ekonomice ve vybraném odvětví národního hospodářství

Jonáš, Ondřej January 2019 (has links)
The aim of this work is to describe the principles of circular economy and bioeconomics and find opportunities for its use in the condition of Czech forestry. To achieve this goal, the method of mapping material flows in forestry in historical, current, and predicting future values was chosen, and key actors in the industry were selected. In-depth interviews were conducted with them and a professional workshop was organized. Based on the discussion, barriers were defined according to the PESTLE method and the list of possible mitigation measures was created, including the selection of the most promising possibilities of using wood biomass locally and with the highest added value.

Bioekonomika: teorinis ir taikomasis požiūriai / Bioeconomy: A Theoretical And Applied Approach

Kniūkšta, Bernardas 14 January 2009 (has links)
Tyrimo objektas – bioekonomikos teorinis turinys ir taikomosios sritys. Darbo tikslas – atskleisti bioekonomikos teorinį turinį ir nustatyti jos apimamas ekonominės veiklos sritis, išryškinant jos sąsajas su darniu vystymusi. Uždaviniai: 1) atskleisti bioekonomikos koncepcijas ir traktuotes; 2) išanalizuoti bioekonomikos vaidmenį ekonomikoje, teikiamą naudą ir keliamą riziką; 3) atskleisti bioekonomikos indėlį į darnų vystymąsi; 4) nustatyti bioekonomikos vystymosi prielaidas. Tyrimo metodai - analizuojant bioekonomikos teorinius aspektus - jos traktuotę bei sankirtą su kitais mokslais - naudoti apibendrinimo ir apibendrinamosios abstrakcijos metodai; analizuojant bioekonomikos vaidmenį pasaulio ekonomikoje, jos teikiamą naudą ir iššaukiamą riziką taikytas loginės analizės metodas; bioekonomikos indėlis į darnų vystymąsi nagrinėtas izoliuojančiosios abstrakcijos metodu; analizuojant tarptautinių institucijų ir Lietuvos požiūrį į bioekonomiką naudoti akademinės, teisinės ir mokslo populiarinimo literatūros bendramoksliniai tyrimo metodai – loginė analizė ir sintezė bei dokumentų analizės metodai. Literatūros ir informacijos šaltinai – Lietuvos ir užsienio mokslininkų darbai, konferencijų medžiaga, tarptautinių institucijų dokumentai, teisės aktai. / Research object – theoretical content and applied fields in bioeconomy. Research aim – to reveal content of bioeconomics, to identify range of economic activities involved in bioeconomy and highlight its connections with sustainable development. Objectives: 1) to reveal approaches and conceptions of bioeconomy; 2) to analyse the role of bioeconomy in the world economy including its advantage and disadvantage; 3) to define contribution of bioeconomy to sustainable development; 4) to define premises of bioeconomy development.

Bioplasty a jejich role na trhu / Bioplastics and their use on market

DĚDEK, Zdeněk January 2014 (has links)
Since the industrial revolution the rise of the global economy depends on using more amounts of fossil fuels. Currently oil is the leading feedstock for the production of various kinds of plastic products, from packaging materials to machine parts. However, even this advanced technology, such as plastic, awarded several Nobel prizes, has its drawbacks. The big disadvantage is their very slow degradation (tens to thousands of years), thereby the accumulation of waste is increasing. Another disadvantage is its production from non-renewable materials (oil). Therefore, the developed economies, including the European Union (EU), are trying to find new alternatives to conventional plastics using biotechnology manufacturers to called bioplastics, which are made from renewable materials. This thesis deals with the use of bioplastics in the market. Using the questionnaires is creating survey of market among producers of bioplastics and consumers, combined with a personal interview with the promoters of bioplastics. Results processed by this methodology showed that the biggest factor, which influence the promotion of bioplastics, is too high price. This is the main reason why the public is so little informed about them. If the price of production decreases, promotion and use of bioplastics will be probably to increase.

Šalies įsitraukimo į biodegalų gamybą vertinimas / Assessment of country’s engagement in biofuel production

Kniūkšta, Bernardas 23 January 2014 (has links)
Tyrimo tikslas – nustatyti įsitraukimo į biodegalų gamybą veiksnius ir įvertinti šalies įsitraukimą į biodegalų gamybą integralumo nacionalinėje ekonomikoje požiūriu. Darbo praktinė vertė. Biodegalų gamyba yra viena iš šiuolaikinės bioekonomikos sričių, kuria susidomi vis daugiau pasaulio šalių. Pastarasis dešimtmetis gali būti apibūdinamas kaip intensyvios biodegalų gamybos plėtros laikotarpis. Šalys, įsitraukdamos į biodegalų gamybą, siekia prisidėti prie darnios energetikos vystymosi. Darbe analizuojama, kaip šalies įsitraukimo į biodegalų gamybą veiksniai varijuoja priklausomai nuo šalies turtingumo naftos ištekliais. Nustatyta, kokie yra dominuojantys įsitraukimo į biodegalų gamybą veiksniai specifinėse šalių grupėse ir kokiu integralumu nacionalinėje ekonomikoje biodegalų gamyba pasižymi šiose šalyse. Tyrimas patvirtina, kad net ir paskatintas politinių iniciatyvų, biodegalų pramonės steigimasis šalyje paprastai grindžiamas išskirtinai didesniu apsirūpinimu biodegalų gamybos ištekliais arba didesne iškastinių energetinių išteklių stoka. Gautos tyrimo išvados gali pasitarnauti formuojant valstybės energetinės politikos gaires alternatyvios energetikos plėtotei. Mokslinio darbo naujumas. Šalies įsitraukimo į biodegalų gamybą vertinimo rezultatai papildo ekonomikos mokslo žinias apie egzistuojančius ryšius tarp ekonominių veiklų plėtojimo ir joms reikalingų gamybos išteklių šalyje gausos. Šių ryšių egzistavimas darbe atskleidžiamas analizuojant bioetanolio gamybą. Tyrimas...

Practical value of the research. The production of biofuels is one of the most modern areas of the bioeconomy, which involves more and more countries around the world. The last decade can be described as an intense period of the development of biofuel production. Engaging in the production of biofuels countries seek to contribute to the sustainable energy development. In this research the analysis of factors of country’s engagement in biofuel production, depending on the oil richness of the country, is performed. It was analysed which factors determine the engagement in biofuel production in different groups of countries and which parameters of biofuel production integration in national economy are satisfied in these counties. The study confirms that biofuel industry establishment in the country, even promoted by political initiatives, is usually based on purely larger self-sufficiency in production resources or higher scarcity of fossil energy resource. The resulting findings can serve in shaping the state's energy policy guidelines for the development of alternative energy sources. Originality of the research work. The obtained results supplement the scientific knowledge in economics about the existence of the relationships between development economic activities and the abundance of necessary production...
