Biomass is a renewable and carbon-neutral resource with good features for producing biofuels, biochemicals, biomaterials. Among the different technologies developed to date convert biomass into such commodities, hydrothermal conversion (HC) very appealing sustainable option, affording marketable gaseous (primarily containing H2, CO, CH4, CO2), liquid (biofuels, aqueous phase carbohydrates, inorganics), solid products (energy-dense biofuels (up 30 MJ/kg) excellent functionality strength). Given these prospects, this publication first-time puts together essential information on HC of lignocellulosic algal biomasses covering all steps involved. Particularly, work reports comments most important properties (e.g., physiochemical fuel properties) from holistic practical perspective. It also gathers vital addressing selecting using downstream/upgrading processes reaction (HHV up 46 MJ/kg), biochemicals (yield >90 %), biomaterials (great surface area 3600 m2/g). As result vision, not only summarizes but analyzes discusses present future applications, establishing an invaluable link between product market needs push transition laboratory industry. Such pioneering approach paves way development, commercialization industrialization develop zero-waste biorefinery processes.

The manufacturing and consumption of plastic products have steadily increased over the past decades due to rising global demand, resulting not only in depletion petroleum resources but also environmental pollution non-biodegradable nature conventional plastics. Moreover, despite being introduced into market as an alternative petroleum-based plastics, biobased plastics are mainly manufactured from agricultural crop-based sources, which has negative impacts on environment livelihoods people. Marine-derived bioplastics becoming a promising cost-effective solution demand for products. physicochemical, biological, degradation properties marine-derived made them substances many applications. However, more research is required their large-scale implementation. Therefore, this review summarizes raw materials such algae, animals, microorganisms, well extraction processes properties. These insights could thus accelerate production novel prevailing by taking advantage marine biomass.

The increasing demand for sustainable alternatives to conventional plastics has propelled the interest in bioplastics. While numerous studies have showcased their environmental advantages, particularly reducing global warming potential and fossil fuel usage, comprehensive reviews on holistic impacts of bioplastics throughout life cycle are scarce. This paper aims fill this gap by critically evaluating sustainability bioplastics, from production disposal. We find that impact is influenced feedstock choices, processing methods, disposal practices. Although intensive agriculture can cause acidification eutrophication as well incomplete biodegradation may lead formation bio-micro/nano-plastics, generally present a lower burden than traditional plastics, evidenced reduced carbon footprint enhanced biodegradability, which contributes decreased plastic waste. Importantly, positively affect soil dynamics, underscoring role promoting agricultural management advocate future Life Cycle Assessment develop inventory database enabling more thorough evaluation impacts. research provides critical insights policymakers viability

Abstract Global solid waste generation is expected to double by 2050 from the present annual level of 2.01 metric ton. Traditional biowaste treatment methods, such as landfilling and incineration, cannot meet need deal with gigantic amounts reduce environmental harm. This review critically evaluates existing sustainable management strategies highlighting their role in transitioning a “reuse recovery” paradigm. Sustainable refers conserving resources protecting human health, society, environment. In this context, examines current advancements potential trends using widely available novel applications produce key biofuels (such biogas biodiesel) corrosion inhibitors, asbestos‐free brake pads, nutrient‐rich functional foods, bio‐cement, bio‐based fertilizer, biodegradable plastic. Among these, biowaste‐to‐energy conversion (e.g., production) plastic synthesis emerge particularly impactful due scalability address both reduction resource recovery goals. The strategic utilization into products holds significant promise mitigating sustainability problems, offering renewable alternatives that are free harmful additives.
