Investigation of flows of waste in Šiauliai region

Atliekų tvarkymas viena iš opiausių problemų Lietuvoje. Komunalinių atliekų kaupimas sąvartynuose kol kas yra pagrindinis atliekų tvarkymo būdas, daug mažiau dėmesio skiriama atliekų rūšiavimui ir skirstymui, dar nėra priimta įrenginėti atliekų surinkimo ir skirstymo punktus, aikšteles. Biologiškai skaidžioms atliekoms priskiriamos maisto atliekos, susidarančios tiek buityje, tiek viešojo maitinimo įstaigose, maisto pramonės atitinkamos atliekos, šalutiniai gyvūniniai produktai iš mėsos ir žuvies perdirbimo pramonių, odų pramonės atitinkamos atliekos, žaliųjų zonų priežiūros ir medienos apdorojimo pramonės atliekos ir kt. Biologiškai skaidžių atliekų tvarkymas įvairiuose Lietuvos regionuose kelia pagrįstą susirūpinimą, kadangi iki šiol neišspręsti didelės dalies tokių atliekų perdirbimo klausimai. Siekiant įvertinti realią situaciją Šiaulių regione ištirti biologiškai skaidžių atliekų, susidarančių šiame regione, srautai, aptarti jų tvarkymo būdai.Waste management is one of the most pressing problems in Lithuania. Collection of municipal waste in landfills is by far the dominant mode, much less attention is paid to the waste sorting and distribution, yet there are no install for the collection and distribution points for the community. Biologically dissolvable waste includes food waste from household or catering, relevant waste from the food industry, by-products of from the meat and fish processing enterprises, waste from the leather industry, maintenance of green areas, wood processing industry etc. Management of the biologically dissolvable waste in various regions of Lithuania raises reasonable trouble as problems of processing of the large part of such waste are not solved. In order to estimate a situation in Šiauliai region flows of the biologically dissolvable waste produced in this region were investigated and questions of their management were discussed. Proposals of possible methods for the management of biologically dissolvable waste in Šiauliai region were presented.Žemės ūkio akademijaVytauto Didžiojo universiteta

Model of investment evaluation of public building based on multiple criteria decision synthesis methods

The theme and subject of this study is very topical for today's Lithuanian tourism market because of the fast development of hotel construction industry, also because of increasing negative tourism market forecast of experts, who are saying what hotel market overstocked in Vilnius. Subject and methods of study: Particular hotel building project in Vilnius city was selected as the research subject and it is taken under consideration in economical aspects. Decision support system applying multiple criteria synthesis methods in construction were applied for results evaluation [...]

Effects on how corn distiller grains with solubles (DDGS) as a replacement for soybean meal (SBM) in a Boer goat diet can improve profitably for producers by saving $0.17 per lbs. of feed

Forty-eight Boer goats were fed a DDGS diet, to which replaced the common SBM diet through 4 separate treatments (Exp. 1 to 4). The experiment is based on evaluating the efficacy of corn dried distiller grains with solubles (DDGS) as a replacement for soybean meal (SBM) in a Boer goat diet to determine growth performance, diet digestibility, carcass traits, and how these outcomes influence profitability for feed producers. Goats were fed a pelleted concentrated diet at Kansas State University’s Sheep and Goat Unit. These feeds either contained no DDGS in replace of SBM (Exp. 1), 33% DDGS in replace of SBM (Exp. 2), 66% DDGS in replace of SBM (Exp. 3), 100% DDGS in replace of SBM (Exp. 4). The study had 16 pens total dedicated to each treatment, with 4 pens containing 3 goats in each. These goats were fed twice a day along with weighing weekly from 0 d to 47 d; 0 d being the start of the experiment. On d 47, the lowest and highest weighed goats were taken out of each corresponding pen for carcass evaluations (hot carcass weight, carcass yield, loin eye area, loin eye depth, back fat, and body wall thickness). After Boer goats were slaughtered, the GLIMMIX procedure of SAS determined the data regarding growth performance (body weight, average daily gain, average daily feed intake, and gain to fed ratio). Overall, carcass traits, growth performance, and feed efficiency had results of acute change in numbers, indicating DDGS lacked the opportunity to cause unnecessary weight gain or loss in goats. From a marketing standpoint, when balancing Exp. 4’s diet compared to Exp. 1; there is a $56.23/ton saving in formulating the feed; converting to$0.17/lbs. basis. Overall, Exp. 4 with only DDGS affected the absence of goat’s comprehensive hot carcass weight and average daily gain in a sustainable and more profitable way. In conclusion, 100% DDGS in Exp. 4 showed no significant negative differences in the goats compared to the usual soybean meal diet in Exp. 1
