Customizable and Waste-Free Pharmaceuticals: PLA-Carbon Pills from Biomass Pyrolysis via FDM 3D Printing

(Corresponding) Koumpakis D., Vlachokostas C., Savva C., Michailidou A., Barmpalexis P., Achillas C.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

The pharmaceutical industry is called to adopt more sustainable manufacturing methods to meet current market needs since traditional drug production creates substantial waste while using much energy and failing to meet individualized treatment requirements. This study investigates circular and...Read more

Bio-oil production from biomass pyrolysis via a hybrid mathematical and machine learning approach

Xu F., Lyons Ceron A., Neshumajev D., (Corresponding) Konist A.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

A hybrid mathematical and machine learning (HMML) approach is applied for maximizing bio-oil yield during the continuous biomass pyrolysis, using local common reed as feedstock. The HMML approach, which combines Response Surface Methodology (RSM) and Machine Learning algorithms (Gaussian Process (...Read more

Designing for Disassembly and Reuse: A Modular Repair Model Proposed in the Manual of Good Practices for the Production and Recycling of Waste from Electrical and Electronic Equipment

(Corresponding) Machado C., Batista S., Gomes A., Fonseca P.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

This paper proposes a modular design approach based on Design for Circular Disassembly (DfCD) to reduce waste and repair costs in Electrical and Electronic Equipment (EEE). Drawing from practical examples and aligned with European circular economic directives, the study demonstrates how product...Read more

Impact of Carbon-Based Materials on the Anaerobic Digestion of Citrus Processing By-product

Pedullà A., (Corresponding) Calabrò P.

Topic:

2. CIRCULAR ECONOMY AND BIOECONOMY

Orange peel waste holds promise for biomethane production via anaerobic digestion, though challenges such as the presence of d-Limonene, an inhibitory compound, and seasonal availability persist. In this study, ensiled OPW was used in Biochemical Methane Potential (BMP) tests to evaluate its...Read more
