“…Renewable energy creates possibilities to be implemented in several sectors: manufacturing, cement, consumer goods production processes, transport, food, or agriculture [1]. Climate neutrality can be promoted via shorter-term EU 2030 goals such as reducing greenhouse gases (GHG) by 40%, increasing the share of the renewable energy sources to 32%, and increasing energy efficiency by 32.5% [2,3].…”

The European Union created a European Green Deal Program (EGDP). This program aims at a sustainable economy through the transformation of the challenges related to climate and the environment. The main goal of EGDP is climate neutrality by 2050. The increase of alternative biomass residues utilization from various food processing industries and cooperation in the energy and waste management sector is required to meet these expectations. Nut shells are one of the lesser-known, yet promising, materials that can be used as an alternative fuel or a pre-treated product to further applications. However, from a thermal conversion point of view, it is important to know the energy properties and kinetic parameters of the considered biowaste. In this study, the energy and kinetic parameters of walnut, hazelnut, peanut, and pistachio shells were investigated. The results showed that raw nut shells are characterized by useful properties such as higher heating value (HHV) at 17.8–19.7 MJ∙kg−1 and moisture content of 4.32–9.56%. After the thermal treatment of nut shells (torrefaction, pyrolysis), the HHV significantly increased up to ca. 30 MJ∙kg−1. The thermogravimetric analysis (TGA) applying three different heating rates (β; 5, 10, and 20 °C∙min−1) was performed. The kinetic parameters were determined using the isothermal model-fitting method developed by Coats–Redfern. The activation energy (Ea) estimated for β = 5 °C∙min−1, was, e.g., 60.3 kJ∙mol−1∙K−1 for walnut, 59.3 kJ∙mol−1∙K−1 for hazelnut, 53.4 kJ∙mol−1∙K−1 for peanut, and 103.8 kJ∙mol−1∙K−1 for pistachio, respectively. Moreover, the increase in the Ea of nut shells was observed with increasing the β. In addition, significant differences in the kinetic parameters of the biomass residues from the same waste group were observed. Thus, characterization of specific nut shell residues is recommended for improved modeling of thermal processes and designing of bioreactors for thermal waste treatment.

“…A number of researchers have criticised this approach 14 and have also identified the problems at the grassroots level that legislators should face in making green public procurement mandatory 15 . A growing number of analyses are emerging that help to understand the path to CPP 16 . Alhola et al 17 identified a number of sectors where CPP can be successful, such as construction, waste and wastewater management, transportation, food, and catering, furniture and textiles.…”

The aim of this paper is to link the concept of green public procurement (GPP) to the nowadays popular circular economy (CE) concept by exploring the possibilities of circular public procurement. The legal framework will be specified at all stages of the suggested procurement cycle (preparation, tendering, execution, monitoring) and the connected instruments that support GPP will be summarized. In the research, ecolabelling and life-cycle costing will be highlighted as tools leading to Circular Public Procurement (CPP), drawing attention to the importance of ensuring competition and cooperation with market actors using these tools.

“…The public procurement expenditure of the EU states exceeds 19% of their GDP, which amounts to about 2.3 trillion Euro annually [55]. In view of its tremendous economic proportions, public procurement is widely recognized as a potentially important tool for implementing the EU Circular Economy Action Plan.…”

Stewardship and administrative capacity in green public procurement in the Czech Republic: evidence from a large-N survey

et al. 2021

View full text Add to dashboard Cite

Background The uptake of green public procurement in the Czech Republic is known to lag behind the European standards. We trace this condition back to the adverse effects of a specific type of decision-making trade-off faced by the Czech public procurement officials, namely the trade-off between stewardship and administrative compliance. The trade-off means that public procurers are aware of administrative risks and complications attendant on the conscientious non-perfunctory implementation of green public procurement. Results The overall result is that public procurers ultimately come to prioritize the contract criterion of the lowest price over ecological criteria. The existence of this trade-off has been generally confirmed by the results of a unique large-N survey of more than 1100 respondents from a group of local public officials and mayors in the Czech Republic. Conclusion We have found that the decision-making of Czech public procurers is affected by the trade-off between stewardship and administrative compliance, which turn out to be mutually conflicting goals. On the one hand, many public procurers do possess a stewardship motivation that shapes their positive attitude to GPP. On the other hand, they are painfully aware of, and seek to forestall, administrative risks and complications attendant on the conscientious, i.e., non-perfunctory, implementation of GPP.
