Context and challenges

On the scale of urban areas or areas characterised by large urbanised zones, scrap or waste biomass not only have an impact but also represent a resource that can be recycled throught processing within the bioeconomy. In cases where biomass management is already in place, the most widespread approach tends to be large-scale collection for centralised processing in large-scale units that are usually located far from the area where the waste biomass is produced.

However, interest is growing in other possible solutions including local small-scale management and recovery. In addition to waste biomass in these areas, different kinds of biomass may also be available, produced by agriculture on the outskirts or even within urbanised areas (urban agriculture or the Creole garden model). Some of these biomasses are potantial resources for small-scale intra- or peri-urban biorefineries aimed at producing high added-value products, but whose development models remain to be consolidated

Goals

In the above context, investigating the benefits of the joint development of diversified, local bio-economic activities in urban areas, would help answer the following question: can co-activity (i.e. one or more types of bio-refinery jointly offering services and products) within a single structure or several development structures increase the value of biomass and make micro-structures more sustainable, particularly when combined with intra- or peri-urban agricultural activities?

To answer this question, B-PAUPS first aims to define original service bioeconomy and product bioeconomy concepts and to clarify the notion of proximity and micro-structure. It will then explore the ways in which solutions linked to the two types of bioeconomy can be combined, by looking at the constraints or opportunities from the point of view of the technologies ('necessary but sufficient' or low-tech technologies; tools for biomass capture logistics) and the economic and governance models that need to be associated with them to ensure sustainability..

B-PAUPS will be a new form of collaboration between Guadeloupean and French research units on bioeconomy issues, and will be able to feed into the "ambition Guadeloupe" plan led by INRAE.
