This review aims to evaluate the production and processing chain of camu-camu (Myrciaria dubia), giving suggestions to maximize the valorization of raw materials, demonstrating new product possibilities from processing to distribution and highlighting the suggested contributions. It is clear that despite the camu-camu pulp has important properties, a large part of its raw material, considered waste (around 50%) and formed by important bioactive compounds, can give rise to new products, such as bioactive extracts to be used by pharmaceutical, chemical and food industries, ingredients for bakery products, dairy and several others sectors, which constitutes opportunities, in addition to contributing to the reduction of agro-industrial waste and the preservation of the environment.

Lignin is a natural phenolic polymer characterized with renewable, sustainable and biocompatible, but yet remain underutilized. In the post-pandemic era, people are conventionally reusing mask but without any disinfections to prevent infection of virus in public places, which could lead to accumulation of bacteria and secondary infections. The development of antibacterial mask from lignin would simultaneously address the hygiene issues of used mask due to microbe accumulation and provide novel approach for lignin valorization.

Contamination of chars with dioxin-like polychlorinated biphenyls (dl-PCB) significantly limits their use and hinders their deployment in the circular bioeconomy, specifically in applications that may lead to dietary exposure. Here, for the first time, we review the levels of contamination of chars produced from pyrolysis and hydrothermal carbonisation (HTC) with dl-PCB congeners. We conduct a detailed and critical examination of the role played by the processing parameters, such as temperature and residence time, and the reaction mechanisms, to detoxify the biomass under an oxygen-free atmosphere during its valorisation.

Background: Purple passion fruit (Passiflora edulis f. edulis) is a highly appreciated fruit typically consumed in fresh or processed into various food products. The peel and seeds, which are by-products of fruit processing, are rich in nutrients and bioactive compounds with potential to be valorised into food applications.

Coffee husks have been valorised by isolating humic materials before (HLS-Raw) or after (HS-Comp) composting them. Such substrates were reacted with chitosan at different ratios to synthesize novel nanoparticles (NP) with radical scavenging properties. Size and antioxidant activity of nanomaterials increased at higher HS/chitosan ratio, while zeta potential decreased.

Lignin, an energy-rich and adaptable polymer comprising phenylpropanoid monomers utilized by plants for structural reinforcement, water conveyance, and defense mechanisms, ranks as the planet's second most prevalent biopolymer, after cellulose. Despite its prevalence, lignin is frequently underused in the process of converting biomass into fuels and chemicals. Instead, it is commonly incinerated for industrial heat due to its intricate composition and resistance to decomposition, presenting obstacles for targeted valorization.
