Regenerative Energie
During the chain from an agricultural bioresource to a food product, by-products and residues are generated. The majority of the residues are handled within urban waste and waste water management structures; the contained valuables regarding the energetic content and nutrients such as N and P are actually inefficiently or not utilized. The mass flows from primary agricultural bioresources to food consumption and the whereabouts of the residues will be analyzed. Similarly the green waste sector is studied on the example of lawn cuttings.
The chain analysis is done for a common scenario with source-separated biowaste collection by bins and waste water disposal into the sewage system. It will be compared with innovative scenarios. In all scenarios substantial and energetic products are generated, but with strongly varying efficiency. The scenarios are based on data of Hamburg’s district of Wandsbek. One of the scenarios is actually under implementation. Visionary a region can be considered as a 'civilization biorefinery†if the majority of bioresources are utilized most efficiently for generation of substantial and energetic products. Wandsbek city quarter 'Jenfelder Au†demonstrates the combination of waste water, waste and energy management including advanced utilization of some secondary and tertiary bioresource fractions. The return of valuables into agriculture (nutrients, organics) is also aspired. In such systems energetic and substantial utilization are not on completion, but have synergetic effects.

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
