Za doseganje cilja evropske energetsko-podnebne politike, da do leta 2050 dosežemo podnebno nevtralnost s prehodom na obnovljive vire energije, je potrebno aktivirati različne razpoložljive ...obnovljive vire, vključno z biološkimi ostanki oz. odpadki. Eden od takih bioloških odpadkov, ki nastaja v velikih količinah in se večinoma nepredelan odlaga v okolje, so ostanki mlete kave. Ker ostanke mlete kave sestavljajo celuloza, hemiceluloza, lignin in proteini, predstavljajo velik potencial tudi kot biogorivo, ki lahko delno nadomesti lesno biomaso pri proizvodnji peletov. V raziskavi smo v laboratorijskih pogojih izdelali pelete iz ostankov mlete kave, ki smo jim dodali različne deleže (0 %, 25 %, 50 %, 75 %) žagovine. Izdelanim peletom smo določili lastnosti in jih glede na izmerjene vrednosti razvrstili v kakovostne razrede po standardu SIST EN ISO 17225-6:2021. Ugotovili smo, da imajo peleti z večjim deležem ostankov mlete kave višjo kurilno vrednost, večjo vsebnost pepela ter nižjo mehansko obstojnost. Peleti, izdelani iz ostankov mlete kave in dodatkom žagovine (50 % ali več), izkazujejo obetavne lastnosti kot vhodna surovina za proizvodnjo peletov.
The proper classification of sharp and infectious waste in situ by the healthcare workers is an important measure of prevention of sharps and other exposure incidents in non-healthcare workers, who ...handle such waste. The aim was to examine the practice of classifying sharp and infectious waste in family and dental practices.
An analysis of 50 bags of infectious and 50 bags of municipal waste from five family and five dental practices for five days in October 2016 at the Health centre Osijek.
Healthcare workers in 70% of the practices deposited sharps in infectious waste. In 56% of infectious waste bags, sharp object were found. More risky bags of infectious waste were produced by family practices (64%), but with no significant differences in relation to dental practices (48%), (P=0.143). Disposing of infectious into municipal waste was the case in 90% of the practitioners, where in 60% of municipal waste bags, infectious waste was disposed. Dental practices produced more risky bags of municipal waste (76%) in relation to family practices (44%), but with no significant difference (P=0.714).
The results of this research point to importance of performing audits of proper disposal of sharps and infectious waste to reduce the risks of injury to non-healthcare workers who come into contact with the said waste. Given results could be used for framing written protocols of proper disposal of sharps and infectious waste that should be visibly available in family and dental practices and for education of healthcare workers.
This volume (‘Former waste disposal sites in dolines and gravel pits’) presents former waste disposal sites in depressions (dolines and gravel pits) using relief analysis of the former and current ...landscape and based on comparing them with one another. A comprehensive methodological approach has been created called the three-dimensional (3D) model, which is used to detect and record unknown, hidden former waste disposal sites in depressions above sensitive aquifers. The research deals with the problem of former waste disposal sites from the viewpoint of discovering them, creating a registry, and studying noticeable surface effects on the landscape (relief, soil, and vegetation).
Sheep's wool and leather shavings tanned without chromium (III) salts would be suitable for fertilization in organic farming, where is the lack of easily accessible fertilizer nitrogen. This ...hypothesis was tested in a two-year field experiment growing asparagus at Rogelj organic farm in Kranj (Slovenia). The block designed experiment with three replicates comprised fertilization treatments with sheep's wool (W), leather shavings (L), cattle manure (FYM) and unfertilized (Ø). Doses of fertilizers were relevant to 0 (Ø), 140 (W1, L1), 280 (W2, L2, FYM) and 560 kg (W3, L3) N/ha. Fertilizers were dosed the first year before the start of the vegetation. Within the next year we followed their subsequent effect. The highest soil mineral N was found in the W2, which produced also the highest asparagus yield (nonsignificant) in the first year. On contrary, NO
-N content in the asparagus crop was small what reflects the good synchrony of N mineralization and consumption of N at W2. Treatments W and L released significantly more N in the next year than the same dose of nitrogen from FYM. The experiment showed that mainly sheep wool represents a quality alternative organic fertilizer.
Ovčja volna in ostružki usnja strojenega brez kromovih (III) soli bi bili lahko primerni za gnojenje v ekološkem kmetijstvu, kjer primanjkuje gnojil z lahko dostopnim dušikom. To hipotezo smo preverjali v dvoletnem poljskem poskusu z vzgojo špargljev na ekološki kmetiji Rogelj v Kranju. V bločnem poskusu smo v treh ponovitvah obravnavali gnojenje z ovčjo volno (W), ostružki usnja (L), govejim hlevskim gnojem (FYM) ter negnojeno (Ø). Odmerki gnojil so ustrezali 0 (Ø), 140 (W1, L1), 280 (W2, L2, FYM) in 560 kg (W3, L3) N/ha. Gnojila smo odmerili prvo leto pred začetkom vegetacije, v naslednjem letu pa spremljali njihov naknadni učinek. V tleh je bilo največ mineralnega dušika pri W2, tudi pridelek je bil največji, vsebnost NO
-N v pridelku špargljev pa je bila majhna, kar kaže na dobro sinhronost mineralizacije in porabe N. Obravnavanji W in L sta imeli tudi v naslednjem letu značilno večje sproščanje N kot enak odmerek dušika iz FYM. Poskus je pokazal, da predvsem ovčja volna predstavlja kakovostno alternativno organsko gnojilo.
'Sustainable Food Waste-to-Energy Systems' assesses the utilisation of food waste in sustainable energy conversion systems. It explores all sources of waste generated in the food supply chain ...(downstream from agriculture), with coverage of industrial, commercial, institutional and residential sources. It provides a detailed analysis of the conventional pathways for food waste disposal and utilisation, including composting, incineration, landfilling and wastewater treatment.
Studies to date on illegal waste dumps in the Ljubljana Plain (Ljubljansko polje), the Iška Alluvial Fan (Iški vršaj), and areas with local water sources in the City of Ljubljana have demonstrated ...that there are great amounts of waste in areas of importance to the Slovenian capital’s water supply. In particular, illegal dumps located in areas where groundwater flows towards pumping stations and where the Sava and Iška rivers flow into the groundwater present a considerable threat to drinking water quality. In addition, shallow groundwater levels and gravel pits increase the vulnerability of the environment even more.
V Sloveniji postaja problematika komunalnih odpadkov vedno bolj aktualna, saj je ravnanje z odpadki eno najslabše rešenih nalog v okviru varstva okolja. Odlaganje na deponije je trenutno najbolj ...običajna praksa ravnanja s komunalnimi odpadki. Posledica neprimernega ravnanja z odpadki je tudi prekomerno sproščanje metana iz odlagališč, zato bo potrebno poiskati primernejše rešitve. V tej raziskavi smo ugotavljali, kakšna je potencialna produkcija metana iz organskih komunalnih odpadkov glede na njihovo različno granulacijo (delci različnih velikosti: >100 mm, 40–100 mm, 10–40 mm in <10 mm). Vzorcem smo predhodno določili delež organske snovi (OS), suho snov (SS), skupni organski ogljik (TOC), dušik po Kjeldahlu (TKN), NH4+ in C/N razmerje. Pred inkubacijo in po njej smo določili kemijsko potrebo po kisiku (KPK). Iz podatkov, pridobljenih v testu biokemijskega metanskega potenciala (BMP), smo izračunali naslednje parametre: kumulativno produkcijo metana, metanski potencial in izplen metana. Izkazalo se je, da velikost delcev pomembno vpliva na metanski potencial organskih komunalnih odpadkov in da bo le-te pred presnovo v bioplin potrebno zdrobiti.

Večstoletno rudarjenje in predelava svinca je uničilo naravno okolje v Mežiški dolini. Uničeni gozdovi so alpsko dolino spremenili v dolino smrti. O problemih življenja v onesnaženi dolini govorijo prizadeti domačini in strokovnjaki, pevec Marjan Smode pa je o dolini napisal nekaj pesmi (med njimi je v Sloveniji najbolj znana Mrtva reka - Dead River); izjave Andrej Šertel, vodja za gojenje in varstvo gozdov Lesna Slovenj Gradec, Karl Markovič, predsednik lovske družine Bistra, Pavel Srebre, Martin Srebre, Marija Šepul, ing. Peter Sovan, vodja projektne skupine za okolje Rudnik Mežica, dr. Bojan Jezernik, zdravnik ZD Ravne na Koroškem, Filip Šepul, kmet.
The consequences of hundreds of years of lead mining in the valley of the river Meža; destroyed forests and have changed the valley into a valley of death. The affected citizens and experts talk about the issues arising from living in the polluted valley. The singer Marjan Smode wrote several songs about the polluted valley (most recognizable of them entitled, Mrtva reka - Dead River). Statements by Andrej Šertel, head of the section for cultivation and protection of the forest Lesna Slovenj Gradec, continuing with Karl Markovič, head of the hunting family Bistra, and participants of the project group for the preservation of Mežiška dolina, Pavel Srebre, Martin Srebre and Marija Šepul as their project leader, the engineer Peter Sovan, a statement by the medical doctor Bojan Jezernik, ending the clip with a statement by a local farmer Filip Šepul.- Information:- Eliminating the consequences of centuries of mining, saving the natural forest and the heavily polluted environment of Mežiška dolina.- Original language summary:

Anhovo, Posočje: kraljica soških voda, vlaganje soških postrvi, nov razvoj po tehnološki sanaciji Salonita, ...izjava Emil BAŠIN, Ribiška družina Soča, Nova Gorica, Jože FUNDA, predsednik Uprave Salonita, soška postrv v vodi, saniran breg v okolici Salonita Anhovo.- Original language summary:
Anhovo: spodnji tok naše smaragdne lepotice Soče, nižje od tovarne Salonit Anhovo, je bil v enem izmed najnižjih kakovostnih razredov. Izpusti iz tovarne in odlagališča azbesta na rečnih bregovih so življenje v reki skoraj uničili. Pred desetletjem pa je Salonit začel ekološko sanacijo okolice tovarne, tudi bregov reke Soče. Sedaj se v reko ponovno vrača življenje, pa tudi soška postrv.- Anhovo: Downstream from the Salonit Anhovo factory, the quality of our beautiful emerald Soča river was classified within the poorest quality perimeters. The emissions from the factory and asbestos deposits on the river banks have almost destroyed life in the river. A decade ago, Salonit started the ecological rehabilitation of the factory environs, including the Soča riverbanks. Life, including the Soča trout, is now returning to the river.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.
