S pomočjo projekta LIFE BioTHOP do bioplastičnih izdelkov iz hmeljevine

Hmeljevina, stranski produkt pridelave hmelja, predstavlja veliko okoljsko težavo tako v Sloveniji kot tudi v Evropi. Pri pridelavi hmelja se v Sloveniji še vedno množično uporablja sintetična polipropilenska vrvica, ki služi kot opora za hmelj v času rasti, po obiranju storžkov hmelja pa ta ostane prepletena s stebli. Ker je v praksi ločljivost organske biomase in sintetične plastične vrvice nemogoča, je hmeljevina trenutno prepoznana kot odpadna surovina, namesto da bi bila izkoriščena kot dragocen vir naravnih hranil v obliki komposta.

 

Preobrazba hmeljarstva v krožno gospodarsko panogo

Na problematiko neizkoriščenega potenciala odpadne, vendar dragocene biomase poljedelskih kultur, kakršna je hmeljevina, Slovenija odgovarja z mednarodnim projektnim partnerstvom +LIFE BioTHOP+ (www.life-biothop.eu), katerega aktivnosti so se začele julija 2019. Vodilni partner projekta je Inštitut za hmeljarstvo in pivovarstvo Slovenije, ki bo med projektom ‘BioTHOP’ ponudil sonaravno in trajnostno preobrazbo hmeljarske panoge iz linearnega modela upravljanja v sodobno krožno gospodarsko panogo. V projektni konzorcij sta poleg partnerjev iz Španije, Nemčije, Portugalske in Češke vključena še dva slovenska partnerja, Razvojna agencija Savinje in Razvojni center orodjarstva Slovenije, TECOS.

 

Prvi izdelki na policah leta 2022

S pomočjo projekta ‘BioTHOP’ bo preko komplementarnega povezovanja različnih industrijskih panog in medsebojnega sodelovanja partnerjev iz javnega in gospodarskega sektorja leta 2022 na trgovskih policah mogoče izbirati med različnimi biorazgradljivimi izdelki, kot so biorazgradljiva oporna vrvica za vzgojo hmelja, embalažni produkti in bioplastični kompozitni izdelki na osnovi odpadne hmeljevine. Ti bodo cenovno primerljivi s konkurenčnimi izdelki na osnovi sintetičnih polimerov, mehansko vzdržni ter certificirani za domače in industrijsko kompostiranje.

 

Bioplastični sadilni lončki

TECOS v tem projektu postavlja proizvodno linijo bioplastičnih sadilnih lončkov, izdelanih iz PLA granulata z dodanimi vlakni odpadne hmeljevine. Ti bodo v prvi vrsti namenjeni vzgoji sadik hmelja, seveda pa bodo po potrjenih standardih primerni tudi za sorodna področja uporabe v vrtnarskem in kmetijskem sektorju.

_hjClosedSurveyInvites Hotjar cookie. This cookie is set once a visitor interacts with a Survey invitation modal popup. It is used to ensure that the same invite does not re-appear if it has already been shown. 365 days _hjDonePolls Hotjar cookie. This cookie is set once a visitor completes a poll using the Feedback Poll widget. It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms. N/A _hjptid This cookie is set for logged in users of Hotjar, who have Admin Team Member permissions. It is used during pricing experiments to show the Admin consistent pricing across the site. Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
