Marine litter is a significant and growing pollutant in the oceans. In recent years, number of studies initiatives trying to assess tackle global threat marine has grown exponentially. Most these studies, when considering macro-litter, focus on floating or stranded litter, whereas there less information available about seabed. The aim this paper give an overview current state-of-the-art methods address issue seafloor macro-litter pollution. includes following topics: monitoring seafloor;...
The long term ambition of energy security and solidarity, coupled with the environmental concerns problematic waste accumulation, is addressed via proposed waste-to-fuel technology. Plastic converted into automotive diesel fuel a two-step thermochemical process based on pyrolysis hydrotreatment. was pyrolyzed in South East Asia plant rendering oil, which mostly consisted middle-distillate (naphtha diesel) hydrocarbons. fraction (170–370 °C) fractionated, its further upgrade assessed...
A detailed molecular fingerprint of raw pyrolysis oil from plastic wastes is a new research area. The present study focuses for the first time on chemical recycling marine litter; we aim to chemically characterize obtained and its distillates (virgin naphtha gasoil) via GC-MS FT-IR. For all samples, more than 30% detected compounds were identified. 2,4-dimethyl-1-heptene, marker PP pyrolysis, most represented peak in signature litter it differentiates commercial gasoil. presence naphthalenes...
Plastics floating in ocean gyres are a popular topic within pollution discussion; however, no simple solution exists to deal with marine litter. Overcoming limitations collection, and perhaps even more the environmentally, technically economically acceptable use of collected material, is paramount importance. This paper presents initial results from converting plastic litter processed as-is, without pretreatment, sorting into gas oil (MGO) compliant ISO8217 DMA standard via pyrolysis...
Emission standards in European Union, designed to reduce the environmental impact of power generation, present a significant challenge for fast-response distributed generation systems based on internal combustion engines. Regulated emissions, such as NOx and particulate matter major concern due their adverse number health effects. Simultaneously, Union strives towards sustainable management plastic waste seeks ways its upcycling production new fuels chemicals. As an answer presented...
Waste plastics/pyrolysis oil (WPO) obtained from a batch rotary kiln pyrolysis reactor was collected and stored for 60 months in dark at 10 °C, periodically thoroughly characterized changes physical chemical properties finally tested as the drop-in fuel power generating units. Changes during storage were manifested through chain length increase C5-C33 to C5-C43 distillation curve shift 150 °C. The attributed repolymerization reactions consequently lowered alkene alkane ratio, occurring slow...
Abstract This conference contribution will present a novel technology for renewable ash-free fuel production from low-value ash-containing feedstocks such as sludge digestate, wood bark or rice husks that cannot be utilized directly heating fuel, because of the high (low melting point) ash content. Biomass Ash Removal (BiAR) process introduces low-temperature solvolysis in cheap solvents to transform organic matter into liquid state, allowing its separation solid by simple filtration...
Abstract Gasification seems to be a promising technology for small scale power generation, but while coal gasification has long history and many facilities operate the process successfully, biomass hasn't same success. Biomass gasifiers are usually based on “down draft” or “up configuration not able guarantee good quality syngas. Besides, they require very dry selected feedstock, gas' cleaning is difficult complex. Fluidized‐bed also feedstock's preparation in terms of size moisture quite...
