Summary
Sustainable waste utilization is achieved by using only process-generated energy for greenhouse residue conversion. High methane yields and heat recuperation enable efficient, eco-friendly biomass processing without external catalysts.
Area of Science:
- Sustainable energy
- Waste valorization
- Biomass conversion
Background:
- Developing sustainable techniques for waste utilization is crucial.
- Greenhouse residues represent a significant waste stream with potential for valorization.
Purpose of the Study:
- To investigate the complex utilization of greenhouse residues on a commercial scale.
- To assess the feasibility of running the technology solely on process-generated energy.
Main Methods:
- Implementing multilevel heat recuperation for energy efficiency.
- Optimizing conditions for high methane yields from biomass.
- Analyzing labile carbon, nitrogen availability, and inhibitor formation.
Main Results:
- The technology operated using only 8% of the process's generated energy.
- Achieved high methane yields exceeding 340 m³ per ton of volatile solids.
- Identified the critical role of labile carbon availability in phytomass utilization, challenging traditional carbon-to-nitrogen ratio beliefs.
Conclusions:
- Complex utilization of greenhouse residues is feasible on a commercial scale.
- The process is energy-efficient, relying solely on self-generated energy.
- Labile carbon availability is a key factor in efficient biomass conversion, more so than C:N ratios.

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...
