A Span­ish joint ven­ture has devel­oped a new sus­tain­able pack­ag­ing mate­r­ial made from olive waste. Called Oli­past, this biodegrad­able and com­postable plas­tic com­pound can be used to make prod­ucts such as trays, plates and caps for con­tain­ers designed for the pack­ag­ing of olive oil.

The two-year Go-Oliva project was launched in Novem­ber 2019 with the aim of cre­at­ing an eco-friendly and com­postable mate­r­ial to be used for oil pack­ag­ing. The project is a joint ven­ture of Span­ish plas­tics tech­nol­ogy com­pany Aim­plas Tech­no­log­i­cal Insti­tute of Plas­tics and the olive oil coop­er­a­tive Oli­var­era de los Pedroches (OLIPE).

Spain is the lead­ing olive oil pro­ducer and pro­duces a sig­nif­i­cant amount of olive-pit debris — a waste prod­uct of the olive press­ing process. The pro­jec­t’s researchers inves­ti­gated how to recy­cle the waste and trans­form it into a sus­tain­able new mate­r­ial.

“The aim of this project is to cre­ate a new high added-value appli­ca­tion from olive-pit waste by means of the devel­op­ment of new mate­ri­als to pro­duce sus­tain­able pack­ag­ing for olive-oil related prod­ucts,” Belén Redondo, a researcher at AIMPLAS, told Olive Oil Times.

“This waste was treated by ener­getic val­oriza­tion, or incin­er­a­tion, until now. On the one hand, raw mate­ri­als are biodegrad­able poly­meric matri­ces for the new com­pound,” Redondo said. ​“On the other hand, the olive pit has to be treated to be incor­po­rated in poly­meric matri­ces. The olive pit is ground to obtain a micro­met­ric par­ti­cle size.”

As a plas­tic com­pound mate­r­ial, Oli­plast can be processed by the same extru­sion and injec­tion mold­ing meth­ods for the pro­duc­tion of plas­tics, and trans­formed into sus­tain­able pack­ag­ing for olive oil-related prod­ucts. These include caps that can be used for pack­ag­ing con­tain­ers meant for olive oil-based cos­met­ics or small dishes that can be placed under a bot­tle of olive oil to avoid spillage.

The next stage of the GO-OLIVA project, which runs through the end of 2021, is to con­duct a behav­ioral study.

“The new mate­r­ial and the final prod­ucts will be char­ac­ter­ized to ana­lyze if they ful­fill all the require­ments needed for the final appli­ca­tions,” said Redondo.

This will be fol­lowed by an envi­ron­men­tal study to exam­ine the new material’s com­posta­bil­ity.

“Oli­plast could be avail­able within one year from the end of the project,” she added.

The GO-OLIVA project is co-funded by the Span­ish gov­ern­ment and the Euro­pean Agri­cul­tural Fund for Rural Devel­op­ment (EAFRD) under the Euro­pean Inno­va­tion Part­ner­ship (EIP-AGRI).

Pre­vi­ous research stud­ies have exam­ined how left­over waste from olive oil pro­duc­tion, and in par­tic­u­lar ground olive pits, could be recy­cled and trans­formed into clay bricks and cement paste to be used as build­ing mate­ri­als, for the mak­ing of dec­o­ra­tive fur­ni­ture, and even for the pro­duc­tion of noise bar­ri­ers.

A Turk­ish com­pany also pro­duces plas­tic micro-beads from olive pits for the cos­met­ics indus­try.
