PhD Position 4: Doctoral Researcher – Organic Geochemistry (Biochar-Now Project)

Reference Number: 11327

Department: Organic and Earth Surface Geochemistry

Research Project: Biochar-Now

Location: Potsdam, Germany

Application Deadline: 26 July 2026


Contribute to Climate Change Solutions Through Biochar Research

Climate change is one of the greatest scientific and societal challenges of our time. While reducing greenhouse gas emissions remains essential, scientists increasingly recognize that removing carbon dioxide (CO₂) already present in the atmosphere will also play a crucial role in achieving global climate targets.

To support this goal, the Helmholtz Centre for Geosciences (GFZ) is offering a fully funded PhD position within the Biochar-Now project. This research initiative explores how biochar produced from municipal waste materials can contribute to long-term carbon storage while minimizing environmental risks.

Funded by the Federal Ministry of Research, Technology and Space, this project combines organic geochemistry, environmental science, analytical chemistry, and sustainability research. It offers doctoral researchers the opportunity to develop practical solutions for carbon dioxide removal (CDR) and sustainable waste management.


Research Project Overview

Biochar is a carbon-rich material produced by heating biomass in the absence of oxygen through a process known as pyrolysis. Because biochar remains stable in soils for long periods, it can store carbon that would otherwise return to the atmosphere as carbon dioxide.

The Biochar-Now project investigates whether different municipal waste streams can be safely converted into biochar suitable for long-term carbon sequestration.

Potential feedstocks include:

  • Sewage sludge
  • Waste wood
  • Particle board residues
  • Compost screening residues
  • Other organic-rich municipal waste materials

Beyond biochar production, the project also evaluates possible environmental risks, including the release of organic pollutants and heavy metals into surrounding ecosystems.


Research Objectives

The successful doctoral researcher will contribute to several important scientific goals, including:

  • Developing improved methods for producing biochar from waste materials.
  • Assessing the chemical quality of biochar products.
  • Investigating the long-term environmental behavior of biochar.
  • Measuring the release of contaminants under realistic environmental conditions.
  • Supporting climate change mitigation through evidence-based carbon removal research.

The project’s findings will help determine whether waste-derived biochar can become a safe and effective tool for carbon dioxide removal while protecting soil and water quality.


Your Responsibilities

As part of the Biochar-Now research team, you will participate in laboratory research focused on biochar production and environmental assessment.

Your main responsibilities include:

Develop Biochar Production Processes

Investigate efficient methods for converting different organic waste streams into high-quality biochar using controlled pyrolysis techniques.

The research will compare multiple waste sources to determine which materials provide the greatest environmental and climate benefits.


Analyze Organic Pollutants and Heavy Metals

Use advanced laboratory techniques to examine the chemical composition of produced biochar.

Special attention will be given to:

  • Organic contaminants
  • Heavy metal concentrations
  • Chemical stability
  • Carbon quality
  • Environmental safety

These analyses are essential for evaluating whether biochar products meet environmental standards for agricultural use.


Perform Leaching Experiments

Conduct laboratory leaching tests that simulate natural environmental conditions.

These experiments help researchers understand how pollutants may be released over time when biochar is applied to soils.

The results will provide valuable information for environmental risk assessment and future policy recommendations.


Essential Qualifications

Applicants should possess:

  • A Master’s degree (or equivalent) in Organic Chemistry, Geochemistry, Geology, Environmental Science, or a closely related discipline.
  • Experience analyzing organic compounds.
  • Good written and spoken English.
  • Strong teamwork and communication skills.
  • An interest in interdisciplinary environmental research.

Candidates with laboratory research experience will be particularly well suited to this position.


Preferred Qualifications

While not mandatory, the following experience will strengthen an application:

  • Biochar production techniques.
  • Pyrolysis research.
  • Leaching experiments.
  • Environmental sampling.
  • Fieldwork experience.
  • A Category B driving licence.

Applicants with previous research related to soil science, environmental chemistry, or waste management are encouraged to apply.
