ELLIPSE

Efficient and novel waste streams co-processing to obtain bio-based solutions for packaging and agricultural sectors

Description

ELLIPSE project will address the valorisation of two heterogeneous waste streams generated in significant amounts in Europe, slaughterhouse waste (bellygrass) and paper and pulp sludge, to produce cost-efficient PHAs for agricultural and packaging sectors, by the co-processing with other organic waste streams such as glycerol from the biodiesel industry and sludge from the dairy industry. The integration of these waste streams as biorefinery feedstocks will allow reducing the volumes of waste destined to landfill or anaerobic digestion, opening new avenues for platform chemicals and bioplastics production while creating additional revenue for the related industries generating the waste, with added advantages of water recycling, decreased soil degradation, ground water pollution and methane emissions.

Objectives

  • To apply effective pre-treatments for heterogeneous paper and slaugherhouse waste and improve the yield of VFA production in acidogenic fermentation.
  • To obtain PHBV copolymers through efficient and sustainable processes and different PHBV grades according to the requirements of the final applications in the personal care and agricultural sectors. 
  • To obtain PHBV-based compounds and wet compounds and demosntrate their performance through the production of prototypes for personal care and agricultural applications.
  • To validate enzymatic and chemical recycling to recover monomers that will be reincoroporated into the production process.
  • To recover nutrients (nitrogen and phosphorous) to be used as bio-based fertilizers. 

Actions

  • Optimisation of the acidogenic fermentation to produce VFAs.
  • Test of innovative membrane reactor technology (AnMBR).
  • Nutrient recovery from hybrid system microalgae cultivation.
  • Impact environmental assessment.

Expected Results

  • Optimised VFA production and recovery from heterogeneous organic waste. 
  • Nutrient and biofertiliser recovery technology (hybrid microalgae cultivation process).

R&D Line

  • Design and development of biological processes of organic waste treatment: anaerobic co-digestion with/without pre-treatment, microalgae, dark fermentation and bio-electrochemistry processes.

BATERURGIA

BATERURGIA

BATERURGIA “research into advanced recycling technologies for obtaining strategic metals from EV batteries”, aims to respond to the challenges posed by the recycling of LIBs and provide knowledge to solve the problems arising from the recovery and selective separation of critical metals to facilitate their use in the manufacture of new batteries or to replace conventional raw materials and introduce them into other production sectors as alternative raw materials.

WoodLi

WoodLi

WoodLi project focuses on the development of bioadhesives for use in the manufacture of wood-based panels used, among others, in the construction sector. The bioadhesive of the WoodLi project will differ from commercial adhesives in that it will be of renewable origin and will not present toxicity problems

FRONTSH1P

FRONTSH1P

Frontsh1p will contribute to further the green transition in the Polish region of Lódzkie. A region that on the one hand, traditionally heavily relies on coal extraction, and on the other hand, has pioneered circular (bio)economy since the early 2000s. The region has always been in the forefront of innovation and has become one of the leading regions in the field of circular economy.

BioSFerA

BioSFerA

BioSFerA aims to develop a cost-effective interdisciplinary technology to produce sustainable aviation and maritime fuels. The overall process, combining thermochemical, biological and thermocatalytic parts is based on the gasification of biomass and other biogenic waste and the 2-stage fermentation of the produced syngas.
