“…But they engage in other materials than paper waste, primarily in briquettes made from wood waste (Basore 1929;Sheridan, Berte 1959;Brožek et al 2012;Brožek 2013b), from energy plants (Plíštil et al 2004(Plíštil et al , 2005Kakitis et al 2010), or from alternative fuels (Kolářová 2011). Their authors concentrate primarily on energy properties, but not on mechanical properties.…”

Brožek M. (2015): Evaluation of selected properties of briquettes from recovered paper and board. Res. Agr. Eng., 61: 66-71.Worldwide increasing energy demand is today permanently covered by a majority of non-renewable energy sources, namely by coal, crude oil and natural gas. This causes the rapid decline of their reserves and the time gets near when they will be run out. Therefore in the last years the exploitation of renewable energy sources has been permanently preferred. One of alternative fuel forms is fuel on the basis of paper waste. In this paper the results of tests are published, which were carried out using six sorts of recovered paper and board (group and grade 1.05, 1.06, 2.02, 2.05, 2.07 and 2.08 according to CSN EN 643:2002), pressed into the form of briquettes. During the tests following briquettes parameters were watched: moisture content, ash amount, gross calorific value, length and diameter, weight, density, rupture force and mechanical durability. It was proved that briquettes made from recovered paper and board compared with briquettes from wood waste are of high density, high mechanical durability and for their rupture, relatively high force is necessary. But at the same time they have high ash amount and low gross calorific value.

“…As can be seen from the data obtained, the increase in moisture content decreased the strength parameter values of the briquettes and thus the resistance against external forces that may act on the briquette. In a study on briquettes obtained from wheat straw, hemp stalk, and cane waste, the specific compression force value was determined as 38–55 N mm −1 44 . Kabas reported that the specific compression force value of briquettes was 35–40 N mm −1 in a study on the production of briquettes from greenhouse wastes 19 .…”

In 2020, world fresh grape production increased to 78.03 million metric tons from 77.00 million metric tons in 2019. Approximately 80% of the grapes produced in the world are consumed as wine and fruit juice. In such a large industry, a huge amount of waste is generated after processing. This waste is generally used as fertilizer and burned inefficiently. In this study, the quality and strength parameters of the briquettes obtained were determined in order to investigate the possibility of using grape wastes as fuel briquettes by compressing them under constant pressure (120 MPa) at three different moisture content levels (6.8%, 9.4%, 12.1%) instead of using them as fertilizer or burning them inefficiently. As a result of the study, it was determined that the compression force, compression stress, specific compression force, and quality parameters such as density, water resistance, tumbler, and shatter index of the briquettes obtained from the briquettes with 6.8% raw material moisture content were in accordance with the international standard, ISO 17225‐3.

In order to evaluate the liming and nitrogen efficiency of cocksfoot (Dactylisglomerata L.) productivity, a field experiment was performed in Western Lithuania’s naturally acidic Retisol area (55°43′ N, 21°27′ E). Based on seven years of research data, dry mass (DM) yield (including first and second cuttings) reliably varied depending on the growing year, from 4.57 to 7.34 t ha−1. The most significant and positive impact on DM yield was obtained by the application of higher liming (6.0 t ha−1 CaCO3) and nitrogen (120 kg ha−1) rates. Liming utilization efficiency (LUE) was affected by the year of growth (although not always significantly), with a 6.0 t ha−1 CaCO3 liming rate and nitrogen fertilization. Nitrogen utilization efficiency (NUE) varied depending on the growing year and N fertilization rate. One of the most effective solutions for improving cocksfoot biomass is to prepare pressed granulated biofuel, which is potentially a good quality raw material for the direct combustion process. The execution and evaluation of technological parameters and properties of produced pellets revealed that cocksfoot pellet humidity reached 10.0% ± 0.6%, whereas pellet density was sufficiently high, and reached 983.8 ± 22.9 kgm−3 DM. The lower calorific value of cocksfoot pellets reached 17.7 MJkg−1. Ash content after pellet burning was relatively high, reaching 7.0–7.6%. Pellet ash melting temperatures were sufficiently high, with ash softening temperature (ST) reaching 1065 °C. Determined emissions of harmful gases from the burning of cocksfoot pellets (CO2, CO, SO2, NOx and unburnt hydrocarbons CxHy) did not exceed the permissible limits.
