“…Waste recycling means repeated use of the resources that have already been used (De Beir et al 2010). Primarily, the effort is aimed at the maximum possible saving of raw material resources, fuels and energy, reduction of waste volume and sustainable economics (Cimpan et al 2016). Secondly, material recycling contributes to environment conservation, but also to prevent pollution (Jagannadha Rao 2015).…”

The objective of the present paper is to confirm or reject the possible use of recycled asphalt to reinforce forest haul roads regarding the technical requirements set by the standards and directives relevant to the construction of forest road surfaces. The hypothesis is based on the presumption that recycled materials, if correctly used, can reach the same construction properties as standard materials, hence their application does not have a negative effect on reinforcement quality. On a selected stretch of forest road, three test sections were constructed with the use of recycled asphalt, however, each of them with a different technological solution. The first section was reinforced with unbound mixture – Type1 without added water, the second section was constructed using a version of vibrated macadam technology, and recycled asphalt was applied to the third section by the method of basic compacting. In each of the sections, tacheometric cross profile measurement was carried out at monthly intervals to monitor the changes in the cross profile shape, and the number of passages of fully loaded logging trucks was registered; static load tests were performed at pre-defined time intervals to determine the deformation moduli such as deformation characteristics of the road surface structural layers. In all three reinforcement versions, the values of deformation moduli observed during the static load tests were between 68–90 % of the values set by relevant standards for these technologies using natural aggregates. However, the tacheometric measurements did not reveal statistically significant changes in the shape of the reinforcement cross-section. Based on the obtained results, applying recycled asphalt to reinforce forest roads seems to be a suitable alternative to natural quarry aggregate used in unbound structural layers. Recycled material needs to meet the regulatory limits for foreign elements and pass ecotoxicity tests, which is evidenced by a certificate on material compliance issued by the test laboratory.

“…However, the increasing material complexity and fast growing urbanization have increased the challenges in collection [13]. The importance of separation cannot be underestimated, as for example recent studies have shown that the share of sorting costs is 30-50% of the total system cost of packaging waste management [14].…”

This study reviews various mechanical sorting options in the field of solid waste. The interest towards the reuse of waste materials is growing due to the tightened regulation and increasing demand for recycling. The effective reutilization of waste material will be needed sorting technologies, which can be based on the different properties, such as density, electric conductivity, and other surface properties. Several technologies based on sorting were presented decades ago, but in the field of waste, several studies have been published recently that demonstrate to theme being is an essential issue currently. The review summarizes the potential mechanical sorting technologies for solid waste, which were discussed in accessible literature during the last decades. The different methods are included, based on the material properties such as, size, gravity, magnetism, surface tension, electric conductivity, or combinations thereof. The emphasis of technologies are targeted at the methods that are suitable for solid waste material, which can be reused as a raw material in the manufacturing of the products, such as composite production. This kind of operating model promote resource efficient production and contributing circular economy. It is concluded that the efficient sorting results of solid waste materials can be achieved by a combination of several technologies, but a lot of studies will be still needed in the future.

“…We modelled two contrasting cases: (1) a simple MRF, reflecting small scale, low technology plants (mainly manual sorting) which are common in Brazil, and (2) an advanced MRF, reflecting more the state-of-the-art in Europe and the US, characterized by larger scale and mechanical sorting complemented with manual sorting. Consumption of electricity (15 and 20 kWh.t -1 , respectively), diesel (0.7 L.t -1 ) and steel wire for bales (0.85 kg.t -1 ) was estimated considering previous work by Cimpan et al (2016. Sorting efficiencies in the two plants are presented in the Table 1-5, the first number represents the MRF low tech: low technology, low to medium capacity, manual picking plant and the second number, represented in red colour, the MRF high tech: high technology, medium to large capacity, mechanical sorting and manual picking plant.…”
