Improving lignocellulosic biomass pretreatment to increase biogas yields (LIGNOBIOGAS)

Contract 16BM/2019

Contracting authority: Executive Unit for Financing Higher Education, Research, Development and Innovation (UEFISCDI), Romania

Program: European and international cooperation Subprogram 3.1. Bilateral/multilateral

Description

The use of lignocellulosic biomass as a source of renewable energy is a field very timely. Romania has a considerable lignocellulosic biomass which can be used for energy production. The aim of this bilateral project is to develop, develop and apply new technologies for the recovery of lignocellulosic biomass by producing a renewable fuel (biogas). The Romanian partner has extensive experience in the development of methods and technologies for converting biomass and waste biomass into biofuels (biodiesel, bioethanol and biogas), and the French partner has a rich experience in producing biogas from organic biomass and lignocellulosic waste, determination of processing and pre-processing technological parameters. The project proposes: ♦determination the chemical composition of different types of lignocellulosic biomass (wood waste, the vineyard waste, sorghum, Mischantus, energetic crops), ♦pre-processing of lignocellulosic biomass before anaerobic fermentation (pretreatment), ♦anaerobic fermentation of untreated and pretreated lignocellulosic biomass for biogas production, ♦biogas composition analysis depending on the feedstock. By complementarity of the two research teams will develop modern technologies for the treatment of lignocellulosic biomass and converting them into biofuels (biogas).

A complex integrated system for technology optimization and superior valorization of the winemaking and viticulture by-products (VINIVITIS)

Summary

The project responds to the demands of SC JIDVEI SRL and SC COTNARI SA which identify more problems that they face: biomass by-product resulted in the viticulture activity and the applied technologies (phytosanitary treatment, herbicide and biomass collection) in order to obtain material costs saving, the soil protection and the final product, the grapes, to be less aggressed and, to ensure a high quality of the harvested biomass. SC TEHNOFAVORIT SA Bontida, SC RIELA ROMANIA SRL Bontida and SC PHENALEX SRL Oradea aim to diversify their portfolio by improving/upgrading the existing products or introducing new ones. After analyzing those demands, solutions that are the objectives of the 5 projects of the VINIVITIS complex project were identified: Biomass valorization: ►Energy recovery: bioethanol and/or fuel for the cogeneration–P1 ►Valorization in the cosmetics industry: extracts and 2 products realization: a mouthwash and a tooth paste based on them–P5 Technologies optimization: ►Application modernization to phytosanitary treatment by improving a phytosanitary treatment machinery from TEHNOFAVORIT portfolio -P2 ►New herbicide technology and an ecological thermal weed-killing machine-P3 ►A modern logistics system for biomass collection: it covers the biomass by-product collection chain having in view the energy recovery: harvest + transport + storage + drying + processing, precursory stages of the energy recovery – P4. A National Strategy for superior valorization of the Romanian viticulture potential is proposed. All 5 projects and the resulting products, which will be socio-economic assessed, respect the real possibilities existing at the economic operators. Other VINIVITIS estimated results: 9 new jobs in research activity; 10 patent applications submitted to OSIM; 6 new products and 1 significant improved product; 7 new/significant improved technologies; 10 new methods/significant improved; 22 articles send for publication; 28 communications at scientific events

Recovery of Precious Metals from Spent Catalysts by Supercritical CO2 Extraction Assisted by Polymers (SUPERMET)

Cod proiect

COFUND-ERANET-ERAMIN-SUPERMET
Contract nr: 48 / 2018

Title

Recovery of Precious Metals from Spent Catalysts by Supercritical CO2 Extraction Assisted by Polymers

Acronym

SUPERMET

Domain

4 – Eco-nano-technologies and advanced materials

Abstract

SUPERMET project proposes to explore an eco-friendly disruptive technology for the recycling of precious metals, especially palladium (Pd) and platinum (Pt), from spent catalysts, e.g. from petrochemistry catalysts, by extraction in supercritical CO2 (scCO2) thanks to complexing polymers bringing the insoluble precious metals into the scCO2 medium. Precious metals are used extensively in applications for catalysis not only in the petrochemistry, but also in the field of automotive (three way catalyst) and in the synthesis of fine chemicals. The scarcity of these metals poses a risk for the European countries which do not have this primary resource.

The pyrometallurgical and hydrometallurgical state of the art techniques developed for the recovery of these metals are energy-intensive, destructive, and generate large volumes of toxic effluents. With our proposed innovative recycling process, the catalytic support and the precious metal remain intact and can be reused as well as the used CO2 and polymer, so that there are no toxic effluents. Due to adjustable solvent properties of scCO2, the dissolved polymer-metal complex can be removed from the CO2 simply by depressurization. So, this new process is eco-efficient and solves a core problem of the state of the art processes.

The SUPERMET project, coordinated by the Charles Gerhardt Institute of Montpellier (ICGM, France), brings together partners from Germany, Romania and France: the Fraunhofer Institute for Chemical Technology (Fraunhofer ICT, Germany), Heraeus Deutschland GmbH & Co KG (Heraeus, Germany), the National Institute for Research and Development in Optoelectronics (INOE, ICIA Cluj-Napoca subsidiary, Romania) and the Supercritical Fluids Innovation Association (IFS, France).

Abstract

The MINTECO project aims to develop an integrated innovative, efficient and ecological technology for the recovery of base (Cu, Pb, Zn) and precious (Au, Ag) metals from Cu and Pb bearing mining waste (CLBM). The project will allow the establishing of a global management methodology to treat historical mining sites and to reduce disposed volumes of metal-bearing waste. The MINTECO project will be tested on a selected case study  on CLMB (3 mining sites identified in Romania, Poland and Turkey) by using pre-concentration methods (mineral processing) to separate non-useful compounds contained in the coarse fractions followed by leaching of concentrated fractions to dissolve all targeted metals and their recovery by innovative techniques (using dedicated synthesized organic molecules, thiosulfates and ionic liquids).  The main steps (pre-concentration/ leaching/ high grade metal recovery) will be studied in detail by research institutes to optimize first relevant process sequences. Then, a global coherent flowsheet will be proposed and the developed technologies will be subsequently validated by the industrial partners (SMEs) in the project at TR>4. Also, a final economic and environmental assessment will be performed. The consortium gathers 8 partners from 4 countries (France, Romania, Poland and Turkey) and is composed of 3 research institutes,1 university, 1 public institution and 3 SMEs with complementary expertise.

Project objective

The global objective of the MINTECO project is the development of an integrated innovative, efficient and ecological technology for the recovery of base and precious metals from copper and lead bearing mining wastes. The project will allow the establishing of a management strategy to treat and reduce disposed volumes of high metal content waste and plans to contribute to the reduction of Europe’s dependence on raw material imports. Also, the project targets the reduction of polluted emissions to air, soil, and water.
