ADDITION OF BOILER CHARCOAL WASTE TO COMPOST FOR USE AS SUBSTRATE FOR VEGETABLE SEEDLINGS REA
Lorin,Higor E. F.; Costa,Mônica S. S. de M.; Chiarelotto,Maico; Santos,Francielly T. dos; Costa,Luiz A. de M..
ABSTRACT The recovery of waste from the broiler production chain (BPC) is consistent with the principles of a circular economy. Besides turning waste into organic compost, its use as substrate for the production of vegetable seedlings further increases its economic value. However, it is necessary to adapt its characteristics to enable its use as substrate. To this end, the addition of boiler remnant charcoal wastes (BCW), another type of waste generated in the BPC, to the organic compost resulting from the composting of BPC waste with different bulking agents (BAs) was studied. The addition of BCW to agro-industrial compost reduced the electrical conductivity (EC) of substrates. Multiple linear regression showed that, of the 13 variables (physical,...

Managing the analytical challenges related to micro- and nanoplastics in the environment and food: filling the knowledge gaps ArchiMer
Alexy, Pavol; Anklam, Elke; Emans, Ton; Furfari, Antonino; Galgani, Francois; Hanke, Georg; Koelmans, Albert; Pant, Rana; Saveyn, Hans; Sokull Kluettgen, Birgit.
This paper identifies knowledge gaps on the sustainability and impacts of plastics and presents some recommendations from an expert group that met at a special seminar organised by the European Commission at the end of 2018. The benefits of plastics in society are unquestionable, but there is an urgent need to better manage their value chain. The recently adopted European Strategy for Plastics stressed the need to tackle the challenges related to plastics with a focus on plastic litter including microplastics. Microplastics have been detected mainly in the marine environment, but also in freshwater, soil and air. Based on today’s knowledge they may also be present in food products. Although nanoplastics have not yet been detected, it can be assumed that...
