• Stimulating cheap renewable energy is not the same as creating

a cost effective energy system.

• Energy hubs can enhance the volume of renewable energy

effectively

• but they can also help balance the system

• at low cost

High density livestock + limited availability of

land → manure problem, need for cost

effective solution

Legislation that enforces manure processing

Companies want to improve their footprint

(CO2, water) and enhance their corporate

brand image

→ Solve actual problem

→ Improve business case

→ Extend circular economy

(Inter)national demand for nutrients,

(sustainably produced) fertilizers

National demand for green gas

(Inter)national demand for investments in

sustainable projects

Poor business cases for traditional manure

treatment / digestion

Financial incentives (e.g. SDE+ subsidy) that

encourage energy recovery from waste

◼ Uncertainty: minerals value

◼ Uncertainty: legal framework

◼ Uncertainty: scale-up

01 oktober 2019

Lessons learned

◼ A window of opportunity doesn’t guarantee success

◼ Large scale allows industrial approach and solutions

◼ Assumptions need to be constantly challenged and checked

◼ Ideally all players in the value chain need to be involved

◼ Strategic partnerships = partner(s) with a strategic interest (constraints)

◼ Value from manure from a circular perspective (not: biogas production)

◼ Technology issues can be solved

HVC recycling strategy

Source separation in less

populated areas

36

Dutch goals:

• 2020: 75% separation and 100 kg/inhabitant

• 2025: 30 kg/inhabitant

Mechanical sorting in

densely populated areas

Source separation vs mechanical sorting

SSOW

• + Less contamination, therefor possible to

recycle as compost in agriculture;

• - Big seasonal pattern in garden fraction and

less gas in garden fraction.

37

SSOW* (GFT) vs OFMSW (ONF)

*Source Separated Organic Waste

OFMSW

• - More contamination (like batteries) therefor not

possible to use compost in agriculture;

• + Smaller seasonal pattern and more gas.

Average from 9 chemical analyses 2018

Current conversion route

With a large portion wet, low calorific material at once the

material doesn’t combust anymore, results in lower

throughput.

Similar to source seperated material, so why not also do

anaerobic digestion?

Discussion

Is it possible to get the organic fraction clean enough to be recycled

as compost in agriculture?

If not, is combustion as biomass better than combusting in a waste

to energy facility?

Landfill gas

• Large quantities of waste generate vast quantities of methane

• 12% of anthropogenicmethane emissions are fromlandfills

• Different regulations specifythat LFG should be collectedand treated

• Landfill owners are looking at robust and cost efficient gas treatment solutions

• 60% in a cogeneration unit of 10MW

• 40% biogas upgrade-to-grid with a membrane technology

In 2015 the existing technology based on granular iron oxide adsorbent was replaced with a THIOPAQ® that came in operation in 2016. After getting familiar with the process, the client managed to keep the process up and running and take advantage of its performance.

• 5.500 tons of waste collected at the Municipal Sanitary Landfill West of Caucaia (ASMOC)

• August 2017 up to 150,000 m3 of biomethane per day (6250 Nm³/h) are processed.

• Second largest in Brazil, adapting to the National Policy on Solid Waste, approved in 2010.

• The Ceará Gas Company is responsible for the distribution of the biogas, which already has Cerbras as its first customer.

• Low cost per kg S removed

• Easy operation and high availability.

• Proven constant high H2S removal efficiency: 97-99%

• Can work with different biogas upgrade methods:• membrane units • high pressure absorption

• Minimum generated waste. Sulfur recovery ~95%

• bioSulfur can be further used as agricultural fertilizer.
