Recovering Biowaste

Does your company produce biowaste?

Would you like to recover energy from this

waste rather than dispose of it expensively?

We will assess your waste’s potential

energy, develop custom concepts based on

that and use processes of thermal energy

conversion to supply you with heat,cooling

and power for your needs.

Biowaste’s specific properties frequently

preclude its use in conventional conversion

processes. It elemental composition of chlo-

rine, sulfur and alkali constituents present

major challenges and are responsible for

premature ash fusion, corrosion and high

concentrations of pollutant gases.

This is where we come in: On the basis of

feasibility studies, we will develop custom-

ized value chains for distributed utilization

Conversion Concepts to Recover Your

Waste

– Material and energy footprints

– Process engineering and design of com-

bustors including flue gas purification

and heat extraction

Infrastructure for Excellent Research

Fluidized Bed Combustion

– Laboratory and pilot units with thermal

outputs of 15 kW to 150 kW for station-

ary and bubbling fluidized beds

Fuel and Ash Analysis

– Laboratory facilities of our own and

collaboration with fuel laboratories and

academic institutions

– Ash tests of pure and blended fuels,

ash fusion point analyses using heating

microscopes

– Chemical waste analysis to identify

elemental constituents that form ash

– Fuel conditioning, e.g. drying, blending,

milling, pelletizing and additizing

Our References

Model Projects

– “Straw Combustion”: Development of a

distributed combustor with cogeneration

for the fuel straw

– “MDE4”: Utilization of municipally

produced biomass for distributed heat

supply

– “EnerSpreu”: Recovery of energy from

agricultural waste from combine har-

vesting

Sectors

– Agriculture, livestock farming and

forestry

– Municipal facilities

– Waste disposal

– Energy supply, especially biogas plants

From the Idea to the Concept

Custom Fuel Analyses

– Study and assessment of potential

– Fuel analysis compliant with current

standards, including ultimate, proximate

and heating value analysis, thermogra-

vimetry, determination of autoignition

temperature, particle size distribution,

transport and storage properties and ash

sintering analyses

Concepts for Low-emission Combustion

To meet the requirements of pollution con-

trol laws and make the potential energy of

your waste fully recoverable, we provide:

– Combustion tests of biowastes and

blends, among other things, with

varying moisture, to simulate different

climatic harvesting conditions

– Staged-air combustion

– Flue gas recirculation

– Waste additization to bind chlorine and

sulfur compounds in ash

– Control of ash fusion by employing fuel

additives or additized bed mate rials

– Determination of need for secondary

pollutant gas reduction

– Assessment of material recovery paths,

e.g. use as fertilizer

Some of the Biomass Studied

– Straw, wheat chaff and husks, barley,

rape, soy and rice

– Feed waste

– Broken grain

– Landscaping material, green waste, root

wood

– Digestate from biogas plants

– Biowaste from the pharmaceutical

industry, e.g. chestnut, ginkgo and

hawthorn
