Bio-based adhesives from spent coffee grounds: A sustainable pathway using medium chain length polyhydroxyalkanoates.

This study explores the synthesis of medium chain length polyhydroxyalkanoates (mcl-PHA) from Spent Coffee Grounds (SCGs) oil, and its application as a bio-based Pressure Sensitive Adhesive (PSA) for food packaging materials. The mcl-PHA was produced through the bioreactor fermentation of Pseudomonas resinovorans, yielding 40 % (g/g) under single pulse modality. The polymer showed heterogenous monomer composition from C6 to C18, endowed with 20 % unsaturation.

Sustainable Microwave-Assisted Extraction of Hemp Seed Oil as Functional Additive into Polybutylene Succinate (PBS) Films for Food Packaging.

In this study, microwave-assisted extraction (MAE) was performed to recover antioxidant hemp seed oil (HSO) with the purpose of developing polybutylene succinate (PBS)/HSO-based films for active packaging to improve food shelf-life. It was found that MAE achieved comparable yields, structural characteristics, and antioxidant activity to Soxhlet extraction, but in significantly less time (2.5 min vs.

Citrus Wastes as Source of Pectin and Bioactive Compounds Extracted via One-Pot Microwave Process: An In Situ Path to Modulated Property Control.

In this paper, citrus pomace was used as a source of pectin and polyphenols extracted in one pot solution by microwave-assisted extraction (MAE) and conventional extraction (CE) methods. MAE parameters were optimized to maximize yield and adjust in situ final physicochemical properties of extracted pectins, such as the methylation degree (DM), significantly influencing pectin functionality and application. Citric acid (CA) and acetic acid (Hac) were employed as solvents to mitigate pectin degradation.

Exploring Antimicrobial Compounds from Agri-Food Wastes for Sustainable Applications.

Transforming agri-food wastes into valuable products is crucial due to their significant environmental impact, when discarded, including energy consumption, water use, and carbon emissions. This review aims to explore the current research on the recovery of bioactive molecules with antimicrobial properties from agri-food waste and by-products, and discusses future opportunities for promoting a circular economy in its production and processing. Mainly, antibacterial molecules extracted from agri-food wastes are phenolic compounds, essential oils, and saponins.

The fate of post-use biodegradable PBAT-based mulch films buried in agricultural soil.

The fate of black biodegradable mulch film (MF) based on starch and poly(butylene-adipate-co-terephthalate) (PBAT) in agricultural soil is investigated herein. Pristine (BIO-0) and UV-aged film samples (BIO-A192) were buried for 16 months at an experimental field in southern Italy. Visual, physical, chemical, morphological, and mechanical analyses were carried out before and after samples burial.

Upgrading cardoon biomass into Polyhydroxybutyrate based blends: A holistic approach for the synthesis of biopolymers and additives.

Cardoon, Cynara cardunculus L. represents a biorefinery crop with a great potential in the bioplastic field. This work investigates the valorization of different cardoon components into high added value products, finally recombined into novel upgraded bioplastics.

Effect of supervised exercise training on musculoskeletal symptoms and function in patients with type 2 diabetes: the Italian Diabetes Exercise Study (IDES).

Musculoskeletal disorders are common in subjects with type 2 diabetes mellitus (T2DM) and may represent a barrier to physical activity (PA). In the Italian Diabetes and Exercise Study, we assessed whether a strategy aimed at minimizing the risk of injury and worsening of musculoskeletal symptoms favors participation in exercise training and results in improvements in joint-specific functional scores, along with amelioration of metabolic profile. Sedentary patients with T2DM (n = 606) from 22 outpatient diabetes clinics were randomized to twice-a-week supervised aerobic and resistance training plus exercise counseling (EXE) versus counseling alone (CON) for 12 months.
