Solution Overview

Problem

Current technologies for converting vegetable substances and biologic wastes into biomass for energy production are inefficient, leading to poor valorization of renewable energy sources and high environmental impact, particularly due to low efficiency in biogas combustion and energy production from wet fractions of organic waste.

Innovation Solution

A treating apparatus and method that includes a pre-treatment unit for mechanical pressing and grinding, followed by a treatment unit with motion means and hot air insufflation to exsiccate vegetable substances, potentially enhanced with microwave treatment, to convert these substances into high-efficiency biomass for electric and thermal energy production, utilizing the Organic Rankine Cycle (ORC) and ensuring a null CO2 balance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If biogas combustion is used to produce energy from wet fractions of organic waste, then renewable energy production is achieved, but the efficiency is low and environmental impact is high

Engineering Contradiction:
Improveenergy efficiencyVSAvoidenvironmental impact
Core Design Contradiction:
Loss of energyVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by implementing a pre-treatment unit that mechanically presses and grinds vegetable substances before the main treatment process. This preliminary mechanical processing removes excess water and prepares the material for more efficient subsequent thermal treatment, thereby improving overall energy efficiency and reducing harmful emissions from incomplete combustion

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the physical and chemical parameters of the vegetable substances through a multi-stage process: mechanical pressing changes moisture content, thermal treatment changes temperature and chemical composition, and microwave treatment changes internal energy distribution. These parameter transformations convert low-quality wet waste into high-quality dried biomass with improved combustion characteristics and reduced environmental impact

Inventive Principle:
Principle #35Parameter changes

2Productivity

If vegetable substances are converted into biomass for energy production, then renewable energy sources are valorized, but the current conversion efficiency is poor

Engineering Contradiction:
Improvebiomass production efficiencyVSAvoidenergy conversion efficiency
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent merges multiple treatment methods into a single integrated system: mechanical pressing, thermal treatment with hot air insufflation, and microwave treatment. This combination of different treatment approaches working in sequence achieves superior biomass conversion efficiency that none of the individual methods could achieve alone, maximizing energy valorization while minimizing losses

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces conventional purely mechanical or purely thermal treatment systems with a hybrid system that incorporates microwave treatment. The microwave energy field substitutes for and enhances traditional thermal processing, providing more uniform and efficient heating that dramatically improves biomass production efficiency and energy conversion rates

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If wet fractions of organic waste are used directly for energy production, then waste management is simplified, but the energy production efficiency is low

Engineering Contradiction:
Improvewaste management simplicityVSAvoidenergy production efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent segments the waste treatment process into distinct functional units: a pre-treatment unit for mechanical pressing and grinding, a treatment unit for thermal processing with hot air insufflation, and an optional microwave treatment stage. This segmentation allows each unit to perform its specific function optimally, transforming difficult-to-manage wet waste into efficient energy-producing biomass while maintaining operational simplicity through modular design

Inventive Principle:
Principle #1Segmentation
