1. Treatment of Organic Waste
The course will look at the treatment of organic waste.
In particular, it will discuss:
- Characteristics of a typical Organic Fraction from Municipal Solid Waste (OFMSW)
- Composting
- Anaerobic Digestion (AD)
- Combination of AD and composting
Lecture time: 2 hours
Type of course: Theoretical
2. Management of agricultural waste and crop residues
Introduction:
According to the OECD, agricultural waste is waste from various agricultural operations: ,aterials such as manure and various other wastes from farms, crop wastes and fertilisers that run off the fields and pesticides that enter water, air and soil make up the most significant part. Agricultural waste products may contain material that can be used by humans, but whose economic value is usually less than the cost of collection, transport and processing for beneficial use.
This module will explore:
Agricultural Waste Management
Generation of Agricultural Waste
Utilisation of Agricultural Waste
Creating a Waste Management System (WMS)
Agricultural Waste Management System (AWMS)
Crop Residues Management
Environmental Impacts from Inefficient Use of Crop Residues
Management of Crop Residues for Improving Input Use Efficiencies
Lecture time: 6 hours
Type of course: Theoretical
3. Mechanical-Biological-Treatment (MBT)
The course will discuss Mechanical-Biological -Treatment (MBT).
In particular, it will analyse:
- RDF (Refuse Derived Fuel) classification.
- Characteristics of typical MBT waste input
- Respirometric index
- Mechanical-biological treatment at process level
- MBT plant
- A case study
- A process variant: biodrying
Lecture time: 4 hours
Type of course: Theoretical
4. Waste-to-energy (WtE)
The course will explore the fact that waste management is a global problem, which is essential for the sustainable development of human society and can be realised with different approaches in different regions. By exploring the waste management of certain countries, we will assess the reasons for introducing certain technologies, their added value as well as the legislative framework and possible risks and recommendations to consider.
The course will cover the following topics
- Waste management: a global challenge
- Waste collection: Example Germany
- Waste treatment technologies
- Legislative framework
- Challenges in international waste management
Lecture time: 4 hours
Type of course: Theoretical
5. Basics Packaging waste (plastics, glass, paper, metal)
This module focuses on Packaging Waste.
In particular, these are the topics covered:
- Introduction to Packaging Materials
- Types of Packaging Materials
- Packaging Waste
Lecture time: 5 hours
Type of course: Theoretical
6. Waste Electrical and Electronic Equipment (WEEE)
This course will discuss:
- What is WEEE
- WEEE management
- Recycling
- Urban extraction
- Mechanical treatment
Lecture time: 2 hours
Type of course: Theoretical
7. Tools for a Circular Economy - Introduction to LCA and MFA tools
The increase in the use of WEEE (Waste Electrical and Electronic Equipment) highlights on the one hand the necessity and importance of recycling these materials, but on the other hand the complexity that this recycling entails.
In order to recycle these materials in the best possible way, there are two tools that will be introduced and explained in the course:
- life cycle assessment (LCA)
- combined material flow analysis (MFA)
Lecture time: 8 hours
Type of course: Theoretical
8. Practical exercise - WEEE dismantling
This module contains practical exercises on the dismantling of WEEE by universities in Vietnam, Cambodia and Thailand.
Type of course: Practical
9. Practical exercise - Plastic waste upcycling
Introduction
This module contains practical exercises on plastic waste upcycling from universities in Vietnam, Cambodia and Thailand.
Lecture time: 7 hours
Type of course: Practical
