ANAEROBIC DIGESTION : BRIEF OVERVIEW

52

LIPOR BIO-WASTE

STRATEGY

Anaerobic digestion versus composting AD of source separated wastes offers sustainable alternatives to landfilling, incineration and even to composting, ultimately providing renewable energy and fertilisers. The choice between various treatment options for organic waste and the comparative merits of composting versus anaerobic digestion, depends on the one hand on the nature (suitability) of the waste material and the feasibility of the technology, and on the other hand on the local conditions and needs as well as on the policy, objectives and targets of the local community.

AD is a standard technology for the treatment of organic waste in Europe.

Chemical and biological impurities must also be strictly monitored and limited to allow safe and beneficial utilisation of digestate as plant fertilizer.

Chemical pollutants, contaminants, toxins, pathogens or other physical impurities which cannot be decomposed into harmless compounds by the AD process must not be present in AD feedstock materials.

Anaerobic digestion

Brief overview

COSTS ANALYSIS

55

Source separation and separated waste collection are historically perceived as elements that increases the costs of waste treatment. But, this is only true if source separation is seen separate from the overall management of municipal waste. Source separation adds costs to the waste collection process, but reduces the amount of residual waste and the costs of its management, and should therefore be integrated and optimized, together with the measures for waste minimization and recycling, within the overall system of municipal waste management.

FINAL REMARKS & TAKE HOME MESSAGES

59

FINAL REMARKS

Prevention must be always the first step and the first goal.

On-site and decentralised treatments for Bio-waste must be improved.

Achieved an efficient separate collection of bio-waste:

capture rate (kg/inhabitant)

quality (minimum presence of impurities)

Developing the adequate logistics for collection:

collection system (DtD, Road containers,…)

collection schedule/calendar

resources and equipment (containers, vehicles, compostable bags,…)

Design the proper treatment system(s):

local circumstances and characteristics

technology

operational and maintenance requirements

outputs and quality standards

Develop products &

markets

Improve quality

Increase capture

rate

More & adequate collection schemes Integration with other sectors Share best practices

Exploit synergies R&D BAT Incentives, GPP

Separation collection Quality specifications Awareness & training

skills knowledge competencies commitment confidence

FINAL

REMARKS

TAKE HOME MESSAGES

• AWARENESS AND COMUNICATION STRATEGIES ARE

NEVER ENOUGH

• THINK FOR THE PRESENT BUT SPECIALLY FOR THE

FUTURE

• INVOLVEMENT OF SEVERAL STAKEHOLDERS;

• OPEN TO COMMUNITY = ENGAGED COMMUNITY;

• SHARE KNOWLEDGE & BEST PRACTICES
