About this book
Globally we are being confronted by the depletion of many natural resources as a result of unsustainable use and increasing global population. Although the debate on the bioeconomy has gained momentum in recent decades, the interest in certifications and standards for biobased products is still weak. This book aims to fill this gap by promoting a holistic approach, which covers environmental, social and economic sustainability aspects and pushes forward the development of a circular, biobased economy.
This book promotes the development of sustainability schemes (including standards, labels and certifications) for the assessment of biobased products, which are fundamental to the establishment of a cutting-edge sustainable bioeconomy. Chemical-related, globally relevant case studies are used throughout the book. The content covers a range of issues from upstream and downstream environmental, techno-economic and social assessment, to crosscutting issues such as indirect land use change (iLUC) and end-of-life options. The chapters included in this book will provide a comprehensive review of recent works on life cycle assessment (LCA), life cycle costing (LCC) and social life cycle assessment (s-LCA) methodologies.
An important resource for researchers, industrial professionals and policy makers involved in the bioeconomy.

Bio-Based Products in the Automotive Industry: The Need for Ecolabels, Standards, and Regulations
Simone Wurster, Luana Ladu
At the Hanover Fair in April 2018, the Bioconcept-Car was presented as a model for the future of sustainable mobility. Likewise, a car made of cellulose nanofiber was presented at the Tokyo Motor Show in 2019. Various additional automotive applications for bio-based materials have been developed, some of which are already in use in cars. However, supportive measures for stimulating their market acceptance are needed. Based on a mix of research methods, this article describes how ecolabels, sustainability standards, and regulations might support the market uptake of bio-based car components. In addition, comparison with three other types of bio-based products are provided. The article ends with suggestions for future market development activities.

This article focuses on the end-of-life management of bio-based products by recycling, which reduces landfilling. Bio-plastics are very important materials, due to their widespread use in various fields. The advantage of these products is that they primarily use renewable materials. At its end-of-life, a bio-based product is disposed of and becomes post-consumer waste. Correctly designing waste management systems for bio-based products is important for both the environment and utilization of these wastes as resources in a circular economy. Bioplastics are suitable for reuse, mechanical recycling, organic recycling, and energy recovery. The volume of bio-based waste produced today can be recycled alongside conventional wastes. Furthermore, using biodegradable and compostable bio-based products strengthens industrial composting (organic recycling) as a waste management option. If bio-based products can no longer be reused or recycled, it is possible to use them to produce bio-energy. For future effective management of bio-based waste, it should be determined how these products are currently being managed. Methods for valorizing bio-based products should be developed. Technologies could be introduced in conjunction with existing composting and anaerobic digestion infrastructure as parts of biorefineries. One option worth considering would be separating bio-based products from plastic waste, to maintain the effectiveness of chemical recycling of plastic waste. Composting bio-based products with biowaste is another option for organic recycling. For this option to be viable, the conditions which allow safe compost to be produced need to be determined and compost should lose its waste status in order to promote bio-based organic recycling.

Hybridised sustainability metrics for use in life cycle assessment of bio-based products: resource efficiency and circularity
The development, implementation and social acceptance of resource efficient, circular, bio-based economies require critical understanding of the whole supply chain from feedstock to end-use. Trust, transparency and traceability will be paramount. Though life cycle assessment (LCA) is a universally chosen approach to fulfil this purpose, the nature of data required and the depth of analysis lead to complex interpretations of the findings. Herein, a new set of hybridised, first-line sustainability indicators, drawn from the principles of green chemistry and resource (material and energy) circularity, are reported. These flexible, potentially stand-alone metrics are demonstrated via application to an exemplary comparative LCA, incorporating the hybridised indicators including hazardous chemical use, waste generated, resource circularity and energy efficiency, from the “gate-to-gate” stages for the bio-based case studies and their petro-derived commercial counterparts. These metrics were observed to quantify critical new information relevant to our transition to a circular economy, bridging significant gaps in contemporary environmental impact assessment methodologies. Appropriate additional evaluations that examine the performance of metrics, when the embedded resource efficiency and circularity strategies are omitted, have also been undertaken and reported. The data drawn from employing these methods are crucial to inform and encourage operational optimisation, transparency in sustainability reporting and practices to a significant number of value-chain actors including manufacturers, policy makers and consumers.

Pine (Pinus oocarpa) wood has great economic importance in Brazil. Pine stands represent the second largest reforested area in the country due to their industrial interest. Combining the relevance of industrial pine stands in the country and corresponding environmental concerns, this current study aims to identify and quantify the environmental impacts derived from industrial pine roundwood production in Brazil. The environmental study was developed considering the Life Cycle Assessment (LCA) methodology according to ISO14040 framework. The study convers the life cycle of pine roundwood production from cradle-to-forest gate perspective and considers the current practices in the country. The production system was divided in five main stages: Soil preparation, seedlings plantation, forest management, forest harvesting and infrastructure establishment. The environmental profile was estimated considering characterization factors from the ReCiPe method, in terms of twelve impact categories. According to the results, forest harvesting stage was identified as the environmental hotspot being the main responsible of contributions to nine impact categories under assessment with contributing ratios ranging from 21% (e.g., freshwater eutrophication) to 76% (e.g., photochemical oxidants formation). The high amount of fossil fuel required by heavy machinery used in the activities involved in this stage is behind this result. Soil preparation stage reported also an outstanding contribution in categories such as freshwater eutrophication (37%) and toxicity related categories (≈35%). The rationale behind these contributions is associated with the use of chemical fertilizers, mostly superphosphate. The identification of the environmental hotspots in forest biomass production can assist the Brazilian forest practitioners to improve the environmental profile by means of the optimization of forest practices.
