This study assessed how digestate and the liquid fraction (LF) of digestate would perform as candidate RENURE fertilisers (recovered nitrogen from manure) in nitrate vulnerable zones under the proposed criteria of the Joint Research Centre, namely, (i) a mineral nitrogen to total nitrogen ratio ≥ 90% (Nmin:TN ≥ 90%) or a total organic carbon to TN ratio ≤ 3 (TOC:TN ≤ 3); (ii) limits of ≤300 copper (Cu) mg kg−1 and ≤800 Zinc (Zn) mg kg−1. These criteria were applied to unpublished data (n = 2622) on digestate compositional properties, further amended with data from the literature (n = 180); digestate analysis from seven full-scale biogas facilities (n = 14); and biogas industry stakeholders (n = 23). The results showed that Cu and Zn mostly met the criteria, with compliance rates of 94.7% (of 1035 entries) and 95.0% (of 1038 entries), respectively. Just above 5% (of 1856 entries) met the Nmin/TN ≥ 90% criterion, while 36% (of 1583 entries) met the TOC/TN ≤ 3 criterion, while total compliance was 32% (of 1893 entries). When targeting the LF, total compliance increased noticeably, between 43 and 58% depending on DM range, indicating that LFs are better suited RENURE candidate fertilisers than unseparated digestate.

VUCA world (Volatility, Uncertainty, Complexity, Ambiguity), according to experts of JRC (European Commission's Joint Research Centre), is now a special space that corrupts the integrity of science activity, limits thinking and vision of the situation by politicians. In fact, under such conditions, the only reliable resource for scientific organizations is a commercialization, and the payback is a condition of activity. These factors already pose a threat to global security. The mission orientation proposed by European Union experts is still seen as a rather weak alternative.

Nuclear energy is today the largest single source of carbon free and base-load electricity in Europe. While highlighting its important role in the overall energy mix, it is necessary to address sustainability, safety, and security concerns, in particular nuclear safety and nuclear waste management issues, which influence the public acceptance of nuclear energy. The present paper describes the Joint Research Centre activities in support to the EU nuclear safety policy. It describes the Joint Research Centre role in the EU institutional context, identifies the various customers to which the Joint Research Centre delivers its services, and provides some results of the Joint Research Centre scientific work inherent to nuclear safety.

Abstract The European Commission's Directorate General Joint Research Centre has organized several proficiency tests on the determination of acrylamide (AA) in food. This paper presents the results and outcome of a proficiency test that focused on the determination of AA in crispbread samples. One of the goals was the identification of the influence of different parameters such as analyte extraction or instrument calibration on the analytical results. A set of samples, containing 3 different crispbread samples as well as extracts of one crispbread sample and AA standard solutions, was shipped to each participant. A total of 42 European laboratories reported analytical results that were evaluated by applying internationally accepted protocols and procedures. The study found that, for each sample, the results of 4–8 laboratories were outside the range formed by the target value plus or minus the 2-fold of the target standard deviation; thus, they did not perform satisfactorily. In transferring this knowledge to the data of monitoring databases of AA in food, care must be taken that data are quality controlled, as it is likely that some of them may be biased.

Reported Data

A natural nickel sample was used at the GELINA (Geel Electron LINear Accelerator) neutron source of the European Commission, Joint Research Centre, Geel to measure the neutron inelastic cross sections. The GAINS (Gamma Array for Inelastic Neutron Scattering) spectrometer was employed to detect the emitted γ rays while a 235U fission chamber monitored the neutron flux. We report the preliminary production cross sections corresponding to the first transitions in 58,60Ni in comparison with previously reported data and with TALYS 1.9 calculations performed using the default input parameters.

Professor Ernest Hondros CMG FRS DSc Dr d'U FIM CEng was a renowned British metallurgist and materials scientist, an innovator, leader, inspirational encourager, raconteur and friend to many. At the National Physical Laboratory in south west London, Hondros pioneered the measurement of thermodynamic properties of interfaces in crystalline materials and established the importance of interfacial microchemistry in the mechanical strength of engineering materials. Following a period as Head of the Materials Applications Division at the National Physical Laboratory, Dr Hondros was appointed Director of the Petten Laboratory in the Netherlands, an establishment of the European Commission's Joint Research Centre, and later was appointed Director of the Commission's Institute for Advanced Materials.
